Steve Holliday, Chief Executive, said: 
 
 
"We have made good operational and financial progress against our priorities for 
this year and have delivered a very strong financial performance in the first 
half. Our pre-tax profits were up 16%, supported by lower financing costs, 
delivering higher operating cash flows. We have now filed or implemented new 
rate plans for over 60% of our US rate base and are on track to deliver this 
year's investment programme of GBP3.4bn, financed through internal cash flows 
and borrowings. 
 
 
As we look to the future our focused strategy is being confirmed by the changing 
energy landscape, which creates a number of organic growth opportunities for 
National Grid. With the right regulatory frameworks this will create significant 
value for our shareholders." 
  CHIEF EXECUTIVE'S REVIEW 
 
 
National Grid has made a very good start to what is expected to be a strong 
financial year. This is despite the prevailing economic conditions, which have 
marginally affected our distribution businesses particularly in the US. We have 
made good progress on our stated priorities for 2009/10:- delivering our 
disciplined investment programme, progressing with our US regulatory filings and 
driving efficiency through the phased introduction of our operating model. 
Looking forward, the energy landscape is changing, creating a number of organic 
growth opportunities for National Grid. 
 
 
Priorities for 2009/10 
 
 
Our investment pipeline remains strong.  In the UK electricity and gas markets, 
investment is being driven by changes in sources of gas supply and electricity 
generation (c.40%), and the need for asset replacement (c.60%).  In the US 
electricity and gas markets, investment is being driven by customer additions 
(c.20%), the need for asset replacement (c.50%), system reinforcement (c.20%) 
and the emerging need for renewable generation (c.10%). 
 
 
To date this year we have invested GBP1.5bn and are on target to invest around 
GBP3.4bn for the full year, growing our asset base. This is supported by current 
rate plans and long term contracts and is being financed from internal cash flow 
and borrowings. 
 
 
Our financial position remains robust. Net operating cash flows are GBP747m 
higher than the previous period reflecting a favourable working capital 
movement. We have completed our funding requirement of GBP2.5bn for 2009/10 and 
have already pre-funded GBP1.3bn of our funding requirement for 2010/11. This 
year National Grid has issued long term bonds totalling over $2bn, from its 
Upstate New York regulated entity, Niagara Mohawk, and Massachusetts Electric at 
competitive rates. This is part of our programme to reallocate debt to our US 
operating companies. 
 
 
Our net finance costs for this period have decreased by GBP20m to GBP504m. This 
reflects our variable rate debt benefiting from lower interest rates, along with 
UK deflation positively affecting our index linked debt. We have taken full 
advantage of these lower rates, fixing the majority of our variable rate debt 
portfolio for both the current year and 2010/11. 
 
 
We are committed to financing our business in a manner consistent with 
maintaining an efficient balance sheet and optimising our cost of capital. We 
expect all credit metrics to improve this year, primarily due to the reduction 
in our interest charge. Moody's Investor Services, Fitch Ratings and Standard & 
Poor's have all reaffirmed our credit ratings with stable outlook. 
 
We continue to make progress on our rate case filings in the US. This financial 
year we have made filings in Massachusetts Electric Company and Narragansett 
Electric. In addition we plan to file the Niagara Mohawk electric rate case in 
early 2010 and intend to file a rate case for our Colonial Gas business in the 
first quarter of 2010/11. At the same time we plan to make a consolidated 
filing, combining our Boston and Essex gas businesses into a single rate plan, 
greatly simplifying and improving the transparency of our Massachusetts gas 
regulatory arrangements. 
 
 
We continue to drive efficiency through the phased introduction of our operating 
model. We expect that our 2009/10 regulated controllable costs (excluding bad 
debts) as a proportion of our asset base will reduce significantly from the 8.1% 
reported for 2008/09.  We continue to drive procurement costs down through a 
combination of leveraging National Grid's scale, unit price reductions and a 
decrease in the number of suppliers. We remain on track with delivery of our 
KeySpan synergy savings, at 30 September 2009 we had achieved a run rate of 
$140m. 
 
 
 
 
 
 
 
 
 
 
 
 
Potential growth opportunities 
 
 
When we set out our strategy in November 2006, we noted the significant 
requirement for investment in our chosen markets, the UK and US, driven largely 
by the need for asset replacement, renewable energy policy and customer 
connections. Since that time, there have been clear developments in both UK and 
US energy policy and the regulatory and commercial regimes are now beginning to 
take shape.  In the main they are being driven by specific national and state 
targets for renewable energy supply and reductions in carbon emissions. 
 
 
This changing energy landscape will create a number of opportunities for 
National Grid and other energy companies. These will include the need for 
investment in renewable generation, new transmission systems to connect new 
nuclear stations and onshore and offshore wind generation, smart grids, carbon 
capture and storage projects, interconnectors and strategic gas storage. Whilst 
it is unclear today which of these projects will be appropriate for National 
Grid or their precise timing, we expect that greater clarity will emerge as UK 
and US energy policies continue to crystallise and appropriate regulatory 
frameworks are put in place.  We are clear that we will adopt a rigorous 
approach to the assessment of these opportunities as they emerge and will be 
selective about which we pursue. We will only undertake investments that produce 
an attractive and predictable return for shareholders. 
 
 
 
 
DIVIDEND 
 
 
Reflecting the positive outlook for the year, the Board has approved an 8% 
increase in the interim dividend to 13.65p per ordinary share ($1.1480 per 
American Depositary Share) in line with its long term policy.  The interim 
dividend is to be paid on 20 January 2010 to shareholders on the register as at 
4 December 2009.  A scrip dividend alternative will be offered. 
 
 
 
 
OUTLOOK 
 
 
Current performance remains in line with our expectations. 
 
 
We continue to expect a strong performance from our Transmission and Electricity 
Distribution and Generation businesses.Our Gas Distribution business will 
benefit from increases in net revenues under our UK and US rate plans, but will 
be impacted by negative timing differences, resulting in lower operating profit 
in this business. 
 
 
Net interest charges will benefit from low inflation and the majority of our 
variable rate debt having been fixed at low interest rates. Our full year 
effective tax rate is expected to be in line with last year. 
 
 
Overall we are well positioned to deliver another year of strong performance. 
  BASIS OF PRESENTATION 
 
 
Unless otherwise stated, all financial commentaries are given on a business 
performance basis at actual exchange rates. Business performance represents the 
results for continuing operations before exceptional items, mark-to-market 
remeasurements of commodity contracts and financial instruments that are held 
for economic hedging purposes but did not achieve hedge accounting, and US 
stranded cost recoveries. Commentary provided in respect of results after 
exceptional items, mark-to-market remeasurements and US stranded cost recoveries 
is described as 'statutory'. 
 
 
REVIEW OF RESULTS AND FINANCIAL POSITION 
 
 
Operating profit was GBP1,149m, up 6% on the prior period (up 2% on a constant 
currency basis4). This was primarily driven by good results in our Transmission 
and Electricity Distribution and Generation businesses partially offset by 
timing related items in our US Gas Distribution business. Operating profit 
performance in the first half of the year reflected the expected seasonality in 
our US businesses. 
 
 
Net finance costs were GBP504m, 4% lower than the prior period, reflecting lower 
interest rates and RPI deflation benefiting the accretion on index linked bonds. 
We expect this trend to continue through to the full year but lessen as RPI 
inflation returns.  Profit before tax was up 16% to GBP649m. The tax charge on 
profit was GBP93m, GBP32m lower than the prior period, with the first half tax 
charge under IAS34 reflecting discrete items of GBP67m and the geographical and 
seasonal split of our earnings. For the full year we expect our effective tax 
rate to be in line with last year.Earnings were up GBP123m on the prior period 
at GBP554m. Earnings per share increased 31% from 17.2p in the first half last 
year to 22.5p. 
 
 
Exceptional items and remeasurements for continuing operations 
increased statutory earnings by GBP142m after tax. After these items and 
minority interests, statutory earnings for continuing operations attributable to 
shareholders were GBP696m - statutory basic earnings per share from continuing 
operations were 28.3p compared with 16.2p for the prior period. 
 
 
Operating cash flows from continuing operations, before exceptional items, 
remeasurements, stranded cost recoveries and taxation, were GBP1,607m, GBP747m 
higher than the prior period. 
 
 
Organic investment in our continuing businesses was GBP1.5bn, in line with our 
plans for the year. 
 
 
Our net debt fell to GBP21.98bn at 30 September 2009 compared with GBP22.67bn at 
31 March 2009, reflecting the impact of the weakening of the US dollar - pound 
exchange rate on our dollar denominated debt.

months of the financial year is provided in Note 13 on page 25.

Transmission operating profit was up 8% at GBP637m. Our allowed UK transmission 
regulated revenue increased by 6.7% for electricity and 3.8% for gas at 1 April 
2009 in line with our RPI + X price control allowances. This resulted in 
operating profit from our UK regulated revenue being GBP60m higher than the 
prior period. This was partially offset by operating profit lower in the US by 
GBP15m largely due to timing differences. Operating profit from our French 
Interconnector, which had a particularly strong performance last year, was lower 
by GBP22m. Other items increased operating profit by GBP3m. The period on period 
movement in exchange rates had a GBP20m positive benefit on Transmission 
operating profit. 
 
 
Capital investment in Transmission was GBP660m. Large schemes in the UK include 
load related investment in the Thames estuary and transmission investment in 
renewable generation (which earns an enhanced return). Investment in our US 
transmission networks includes reliability spend in New York and investment on 
the New England East-West Solution (NEEWS) project, where we earn an enhanced 
Federal Energy Regulatory Commission (FERC) return on equity of 12.89%.

Gas Distribution operating profit decreased by GBP21m during the period to 
GBP253m. In the UK, net regulated revenues were up GBP23m, reflecting increases 
under the price control allowance. In addition the re-phasing of UK billing 
between the first and second half of the year increased operating profit by 
GBP104m. In the US, where the vast majority of annual revenue is collected in 
the second half of the year, net revenues were up GBP16m on the prior period. 
This good performance comes on the back of last year's significant over 
recovery, which together with negative timing impacts in this half year, has led 
to a GBP142m period on period decrease in operating profit. Most of this year's 
under recovery is expected to reverse in the second half. In addition, as 
anticipated, the US recession is reducing our customers' ability to pay their 
bills with operating profit down by GBP16m as a result of an increase in bad 
debts. Other items reduced UK and US net operating profit by GBP8m. The period 
on period movement in exchange rates had a GBP2m positive benefit on operating 
profit. 
 
 
During the period, together with our Gas Distribution alliance partnerships in 
the UK, we have replaced around 1,026km of gas mains, resulting in total 
replacement expenditure (repex) of GBP233m. In our US operations customer 
connections have slowed as a result of the US recession. This period we have 
added around 19,000 new customers. Overall, our investment in network 
infrastructure projects in the UK and US resulted in total capital expenditure 
(including repex) of GBP541m this period, 20% up on the prior period. 
We continue to make good regulatory progress in the US. On 14 May 2009 our 
Niagara Mohawk gas rate case, recommended by the New York Public Service 
Commission (NYPSC) staff, was approved in full with a base allowed return of 
10.2% and provided for a $39m increase in revenues. The revenue increase came 
into effect on 20 May.  On 29 May 2009 the New Hampshire gas rate case (covering 
around 1% of our US rate base) was approved. We were disappointed with the 
allowed return on equity of 9.54%, which is out of line with other regulatory 
decisions and we subsequently asked the New Hampshire Public Utilities 
Commission to reconsider the decision.  Last week, the Commission denied our 
motion for reconsideration and we are now considering our next steps. 
Next year we plan to make a rate case filing for Colonial Gas and a consolidated 
filing, combining our Boston and Essex businesses into a single rate plan. Our 
continued programme of refiling rate cases will benefit both customers and 
shareholders by supporting much needed investment and recovery of costs.

* Excludes revenue from stranded cost recoveries. 
 
 
 
 
During the period, operating profit from Electricity Distribution and Generation 
increased by 31% to GBP169m. This period saw an increase in our net revenues of 
GBP29m, primarily reflecting the increase in generation contract revenues. 
Timing related items, mainly relating to an under recovery of income, 
temporarily reduced operating profit by GBP64m. Other items, including a 
reduction in service penalty costs and the absence of non-cash one off items 
incurred last year, increased operating profit by GBP44m. 2008 saw us delivering 
a significant improvement in our upstate New York system reliability 
performance, consistently beating our historic average and avoiding service 
penalties. The period on period movement in exchange rates benefited operating 
profit by GBP31m. 
 
 
We have made solid regulatory progress during the period. As planned in 
Massachusetts and Rhode Island we filed electric rate cases on 15 May 2009 and 1 
June 2009 respectively. These filings will benefit both customers and 
shareholders by supporting much needed investment and recovery of costs. We 
expect a conclusion to be reached around the end of the year in Massachusetts 
and early next year in Rhode Island.

* Excludes investment in joint ventures. 
 
 
Operating profit from our non-regulated and other activities increased by 6% to 
GBP90m. This was primarily driven by an increase in profit in our Metering and 
Grain LNG businesses, partially offset by a reduction in operating profit in our 
Property business. As reported in February, given current market conditions we 
have taken action to defer property sales in order to preserve value. This has 
reduced operating profit by GBP14m compared to the previous period. 
 
 
Metering operating profit was up GBP10m at GBP86m, mainly driven by increased 
revenue, and lower costs and depreciation charges. During the period, capital 
investment in this business was GBP64m, with around 360,000 new meters 
installed.  On 29 April 2009 the Competition Appeal Tribunal in part overturned 
Ofgem's decision to fine us for a breach of the UK Competition Act 1998 and 
reduced the fine to GBP30m but also upheld the original decision in part.  The 
Court of Appeal has granted us leave to appeal the Tribunal's decision both on 
points of law and as to the amount of the penalty. 
 
 
Our Grain LNG business delivered an operating profit of GBP20m, five times that 
of the previous period, as a result of Phase II becoming operational in December 
2008.  During the period capital investment in this business decreased by 51% to 
GBP60m, mainly reflecting the completion of the Phase II capacity extension in 
October 2008. Phase III is currently under construction and is planned to 
complete in late 2010.  This will add a further LNG tank and a second unloading 
jetty, increasing the total annual capacity of the terminal to around 15 million 
tonnes, representing around 20% of total UK gas demand. These investments are 
underpinned by long-term, take-or-pay contracts, which deliver an index-linked 
revenue stream for 20 years.

CAUTIONARY STATEMENT 
 
 
This announcement contains certain statements that are neither reported 
financial results nor other historical information. These statements are 
forward-looking statements within the meaning of Section 27A of the Securities 
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, 
as amended. These statements include information with respect to National Grid's 
financial condition, results of operations and businesses, strategy, plans and 
objectives. Words such as "anticipates", "expects", "intends", "plans", 
"believes", "seeks", "estimates", "may", "will", "continue", "project" and 
similar expressions, as well as statements in the future tense, identify 
forward-looking statements. These forward-looking statements are not guarantees 
of National Grid's future performance and are subject to assumptions, risks and 
uncertainties that could cause actual future results to differ materially from 
those expressed in or implied by such forward-looking statements. Many of these 
assumptions, risks and uncertainties relate to factors that are beyond National 
Grid's ability to control or estimate precisely, such as delays in obtaining, or 
adverse conditions contained in, regulatory approvals and contractual consents, 
unseasonable weather affecting the demand for electricity and gas, competition 
and industry restructuring, changes in economic conditions, currency 
fluctuations, changes in interest and tax rates, changes in energy market 
prices, changes in historical weather patterns, changes in laws, regulations or 
regulatory policies, developments in legal or public policy doctrines, the 
impact of changes to accounting standards,  technological developments and the 
ability to access capital markets and other sources of credit in a timely manner 
on acceptable terms, especially considering the recent deterioration of market 
conditions in the global economy and financial markets.  Other factors that 
could cause actual results to differ materially from those described in this 
announcement include the ability to integrate the businesses relating to 
announced or recently completed acquisitions with National Grid's existing 
business to realise the expected synergies from such integration, the 
availability of new acquisition opportunities and the timing and success of 
future acquisition opportunities, the timing and success or other impact of the 
sales of National Grid's non-core businesses, the failure for any reason to 
achieve reductions in costs or to achieve operational efficiencies, the failure 
to retain key management, the behaviour of UK electricity market participants on 
system balancing, the timing of amendments in prices to shippers in the UK gas 
market, the performance of National Grid's pension schemes and the regulatory 
treatment of pension costs, and any adverse consequences arising from outages on 
or otherwise affecting energy networks, including gas pipelines owned or 
operated by National Grid. For a more detailed description of some of these 
assumptions, risks and uncertainties, together with any other risk factors, 
please see National Grid's filings with and submissions to the US Securities and 
Exchange Commission (the "SEC") (and in particular the "Risk Factors" and 
"Operating and Financial Review" sections in its most recent Annual Report on 
Form 20-F). Except as may be required by law or regulation, National Grid 
undertakes no obligation to update any of its forward-looking statements. The 
effects of these factors are difficult to predict. New factors emerge from time 
to time and National Grid cannot assess the potential impact of any such factor 
on its activities or the extent to which any factor, or combination of factors, 
may cause results to differ materially from those contained in any 
forward-looking statement.  The contents of any website referenced herein do not 
form part of this document.

  NOTES TO THE 2009/10 HALF YEAR FINANCIAL INFORMATION 
 
 
1. Basis of preparation and new accounting standards, interpretations and 
amendments 
 
 
The half year financial information covers the six month period ended 30 
September 2009 and has been prepared under International Financial Reporting 
Standards (IFRS) as issued by the International Accounting Standards Board 
(IASB), and IFRS as adopted by the European Union, in accordance with 
International Accounting Standard 34 'Interim Financial Reporting' and the 
Disclosure and Transparency Rules of the Financial Services Authority. The half 
year financial information is unaudited but has been reviewed by the auditors 
and their report is attached to this document. 
 
 
The following standards, interpretations and amendments, issued by the IASB and 
by the International Financial Reporting Interpretations Committee (IFRIC), are 
effective for the year ending 31 March 2010. None of these had a material impact 
on consolidated results or assets and liabilities. 
 
 
  *  IFRS 8 on operating segments 
 
  *  IAS 23 revised on borrowing costs 
  *  IFRIC 13 on customer loyalty programmes 
  *  IAS 1 revised on the presentation of financial statements 
  *  Amendment to IFRS 2 on share-based payments 
  *  Amendments to IAS 32 and IAS 1 on puttable financial instruments and obligations 
  arising on liquidation 
  *  Amendments to IFRS 1 and IAS 27 on recognition of investments on first-time 
  adoption of IFRS and dividends out of pre-acquisition profits 
  *  Improvements to IFRS 2008 
  *  IFRIC 15 on agreements for the construction of real estate 
  *  IFRIC 16 on hedges of a net investment in a foreign operation 
  *  Amendment to IAS 39 on the effective date for reclassification of financial 
  assets 
 
 
 
The following interpretation and amendments, issued by the IFRIC and the IASB, 
are effective for the year ending 31 March 2010, but have not yet been endorsed 
by the European Union: 
 
 
  *  IFRIC 18 on transfers of assets from customers 
 
  *  Amendment to IFRS 7 on improving disclosures about financial instruments 
  *  Amendments to IFRIC 9 and IAS 39 on embedded derivatives 
 
 
 
The amendment to IFRS 7 and amendments to IFRIC 9 and IAS 39 have no impact on 
the consolidated results or assets and liabilities of the Company. The impact of 
IFRIC 18 is to increase profit for the six months ended 30 September 2009 and 
reduce liabilities as at 30 September 2009; however, the adoption of this 
interpretation did not have a material impact on our consolidated results or 
assets and liabilities and therefore the half year financial information 
complies with both IFRS as issued by the IASB and IFRS as adopted by the 
European Union. 
 
 
The half year financial information does not constitute statutory accounts as 
defined in Section 434 of the Companies Act 2006. It should be read in 
conjunction with the statutory accounts for the year ended 31 March 2009, which 
were prepared in accordance with IFRS as adopted by the European Union and the 
IASB and have been filed with the Registrar of Companies. The auditors' report 
on these statutory accounts was unqualified and did not contain a statement 
under Section 237(2) or (3) of the Companies Act 1985. 
 
 
The half year financial information has been prepared in accordance with the 
accounting policies expected to be applicable for the year ending 31 March 2010 
and consistent with those applied in the preparation of our accounts for the 
year ended 31 March 2009, except for the impact of new standards, 
interpretations and amendments noted above. 
 
 
Date of approval 
This announcement was approved by the Board of Directors on 18 November 2009. 
  2. Segmental analysis 
 
 
The segmental analysis is based on the information the Board of Directors uses 
internally for the purposes of evaluating the performance of operating segments 
and determining resource allocation between operating segments. The Company 
assesses the performance of its operations principally on the basis of operating 
profit before exceptional items, remeasurements and stranded cost recoveries. 
The following table describes the main activities for each operating segment: 
 
 
+------------------------------+------------------------------------------------------+ 
| Transmission UK              | High-voltage electricity transmission networks, the  | 
|                              | gas transmission network in the UK, UK liquefied     | 
|                              | natural gas (LNG) storage activities and the French  | 
|                              | electricity interconnector.                          | 
+------------------------------+------------------------------------------------------+ 
| Transmission US              | High-voltage electricity transmission networks in    | 
|                              | New York and New England.                            | 
+------------------------------+------------------------------------------------------+ 
| Gas Distribution UK          | Four of the eight regional networks of Great         | 
|                              | Britain's gas distribution system.                   | 
+------------------------------+------------------------------------------------------+ 
| Gas Distribution US          | Gas distribution in New York and New England.        | 
+------------------------------+------------------------------------------------------+ 
| Electricity Distribution and | Electricity distribution in New York and New England | 
| Generation US                | and electricity generation in New York.              | 
+------------------------------+------------------------------------------------------+ 
 
 
Other activities primarily relate to non-regulated businesses and other 
commercial operations not included within the above segments, including: 
UK-based gas metering activities; UK property management; a UK LNG import 
terminal; other LNG operations; US unregulated transmission pipelines; US gas 
fields; and corporate activities, including business development. 
 
 
Sales between operating segments are priced having regard to the regulatory and 
legal requirements to which the businesses are subject. 
 
 
The Gas Distribution US segment experiences significant seasonal fluctuations 
owing to weather conditions and peak delivery volumes occurring in the second 
half of the fiscal year. In the UK the pricing methodology for gas distribution 
has a higher capacity delivery component and a lower volume component and so is

A reconciliation of the operating segments' measure of profit to total profit 
before taxation is provided on the face of the income statement. Further details 
of the reconciling items are provided in note 3.

* Includes amounts in respect of the amortisation of acquisition-related 
intangibles (see note 3)  3. Exceptional items, remeasurements and stranded cost 
recoveries 
Exceptional items, remeasurements and stranded cost recoveries are items of 
income and expenditure that, in the judgement of management, should be disclosed 
separately on the basis that they are material, either by their nature or their 
size, to an understanding of our financial performance and significantly distort 
the comparability of financial performance between periods. Items of income or 
expense that are considered by management for designation as exceptional items 
include such items as significant restructurings, write-downs or impairments of 
non-current assets, material changes in environmental or decommissioning 
provisions, integration of acquired businesses, amortisation of 
acquisition-related intangibles and gains or losses on disposals of businesses 
or investments. 
 
 
Remeasurements comprise gains or losses recorded in the income statement arising 
from changes in the fair value of commodity contracts and of derivative 
financial instruments to the extent that hedge accounting is not achieved or is 
not effective. 
 
 
Stranded cost recoveries represent the recovery of historical costs in the US 
related to generation assets that are no longer owned. Such costs can be 
recovered from customers as permitted by regulatory agreements.

  3. Exceptional items, remeasurements and stranded cost recoveries (continued) 
 
 
  *  For the six months ended 30 September 2009 restructuring costs include charges 
  related to the integration of KeySpan of GBP22m (six months ended 30 September 
  2008: GBP19m; year ended 31 March 2009: GBP53m) and transformation related 
  initiatives of GBP26m (six months ended 30 September 2008: GBP5m; year ended 31 
  March 2009: GBP68m). Charges in the comparative periods also included planned 
  cost reduction programmes in our UK businesses of GBP15m for the six months 
  ended 30 September 2008 (year ended 31 March 2009: GBP21m). For the year ended 
  31 March 2009 there was an additional charge for the restructuring of our 
  liquefied natural gas (LNG) storage facilities of GBP50m. On 8 October 2009 we 
  announced plans to outsource elements of our UK shared services organisation and 
  we expect to record the majority of associated costs during the second half of 
  the financial year. 
  *  For the six months ended 30 September 2009 there was an environmental charge of 
  GBP7m (six months ended 30 September 2008: GBP9m) relating to US sites. For the 
  year ended 31 March 2009, the UK charge was GBP37m and the US charge GBP41m. 
  Within this, GBP42m was due to significant movements in discount rates arising 
  from reductions in market risk free rates due to economic conditions together 
  with GBP25m arising from changes in landfill tax legislation in the UK. Costs 
  incurred with respect to US environmental provisions are substantially 
  recoverable from customers. 
  *  For the six months ended 30 September 2009 other costs relate to amortisation 
  charges on acquisition-related intangibles of GBP3m (six months ended 30 
  September 2008: GBP3m; year ended 31 March 2009: GBP5m). 
  *  Remeasurements - commodity contracts represent mark-to-market movements on 
  certain physical and financial commodity contract obligations in the US. These 
  contracts primarily relate to the forward purchase of energy for supply to 
  customers, or to the economic hedging thereof, that are required to be measured 
  at fair value and that do not qualify for hedge accounting. Under the existing 
  rate plans in the US, commodity costs are recoverable from customers although 
  the timing of recovery may differ from the pattern of costs incurred. These 
  movements are comprised of those impacting operating profit which are based on 
  the change in the commodity contract liability and those impacting finance costs 
  as a result of the time value of money. 
  *  Stranded cost recoveries include the recovery of some of our historical 
  investments in generating plants that were divested as part of the restructuring 
  and wholesale power deregulation process in New England and New York during the 
  1990s. Stranded cost recoveries on a pre-tax basis consist of revenue of GBP228m 
  (six months ended 30 September 2008: GBP157m; year ended 31 March 2009: GBP435m) 
  and operating costs of GBP28m (six months ended 30 September 2008: GBP3m; year 
  ended 31 March 2009: GBP9m). 
  *  Remeasurements - net gains/(losses) on derivative financial instruments comprise 
  gains/(losses) arising on derivative financial instruments reported in the 
  income statement. These exclude gains and losses for which hedge accounting has 
  been effective, which have been recognised directly in equity or which are 
  offset by adjustments to the carrying value of debt. The tax charge on 
  remeasurements includes a GBP45m adjustment in respect of prior years (year end 
  31 March 2009: GBP1m). 
  *  The exceptional tax charge of GBP40m in the six months ended 30 September 2008 
  (year ended 31 March 2009: GBP49m) arose from a change in the UK industrial 
  building allowance regime arising in the 2008 Finance Act. This resulted in an 
  increase in deferred tax liabilities.

i) The difference between actual and expected investment return on pension 
assets is reported as an actuarial gain or loss within the statement of 
comprehensive income. 
 
 
 
 
  5. Taxation 
 
 
The tax charge for the period, excluding tax on exceptional items, 
remeasurements and stranded cost recoveries is GBP93m (six months ended 30 
September 2008: GBP125m; year ended 31 March 2009: GBP517m). The effective tax 
rate of 14.3% (six months ended 30 September 2008: 22.4%) for the period is 
based on the best estimate of the weighted average annual income tax rate by 
jurisdiction expected for the full year. The current period rate reflects the 
seasonality of earnings following the KeySpan acquisition as well as other 
discrete items. For the full year we expect the group effective tax rate to be 
approximately 29%. The actual effective tax rate for the year ended 31 March 
2009 was 29.2%.

Comparatives have been restated to present items on a basis consistent with the 
current period classification. 
 
 
i)    Commodity contracts that do not meet the normal purchase, sale or usage 
criteria and hence are accounted for as derivative contracts are recorded at 
fair value and incorporated in other non-current assets, trade and other 
receivables, trade and other payables and other non-current liabilities. At 
30 September 2009 these amounted to GBP196m (30 September 2008: GBP64m; 31 March 
2009: GBP310m). 
 
 
ii)    Details of the guarantees entered into by the Company or its subsidiary 
undertakings at 30 September 2009 are shown below: 
 
 
  *  a guarantee in respect of Ravenswood Unit 40 financing amounting to 
  approximately GBP375m. This expires in 2040; 
  *  a letter of support of obligations under a shareholders' agreement relating to 
  the interconnector project between Britain and the Netherlands amounting to 
  approximately GBP261m. This expires in 2010; 
  *  guarantees of certain obligations in respect of the UK Grain LNG Import Terminal 
  amounting to approximately GBP188m. These run for varying lengths of time, 
  expiring between now and 2028; 
  *  a guarantee amounting to approximately GBP120m of half of the obligations of the 
  interconnector project between Britain and the Netherlands. This expires in 
  2010; 
  *  guarantees of the liabilities of a metering subsidiary under meter operating 
  contracts amounting to GBP53m. These are ongoing; 
  *  an uncapped guarantee, for which the maximum liability is estimated at GBP40m, 
  to The Crown Estates in support of the transfer of the interconnector between 
  France and England to National Grid Interconnectors Limited as part of the 
  Licence to Assign Lease. This is ongoing; 
  *  letters of credit in support of gas balancing obligations amounting to GBP26m, 
  lasting for less than one year; 
  *  guarantees of GBP14m relating to certain property obligations. The bulk of these 
  expire by December 2025; 
  *  collateral of GBP15m to secure syndicate insurance obligations which are 
  evergreen; 
  *  guarantees in respect of a former associate amounting to GBP14m, the bulk of 
  which relates to its obligations to supply telecommunications services. These 
  are open-ended; and 
  *  other guarantees amounting to GBP90m arising in the normal course of business 
  and entered into on normal commercial terms. These guarantees run for varying 
  lengths of time. 
 
 
 
iii)    Includes commitments largely relating to gas purchasing and property 
remediation of GBP640m (30 September 2008: GBP195m; 31 March 2009: GBP615m). 
 
 
In last year's Annual Report and Accounts we reported a decision by the Gas and 
Electricity Markets Authority (GEMA) (the "Decision") to levy on us a fine of 
GBP41.6 million for a breach of the UK Competition Act 1998 in respect of term 
contracts with gas suppliers entered into by our UK metering services business 
in 2004.  We also noted that we had appealed the Decision to the Competition 
Appeal Tribunal (the "Tribunal"). On 29 April 2009, the Tribunal overturned the 
Decision in part and reduced the fine to GBP30 million but upheld the original 
Decision in part.  The Court of Appeal has granted us leave to appeal the 
Tribunal's decision both on points of law and as to the amount of the penalty. 
 
 
As at the date of this announcement, we remain of the view that an outflow of 
economic benefits is not probable, and as a result, no provision has been made 
in these accounts either for the reduced fine of GBP30 million, or for any other 
possible financial impact of the ruling. 
 
 
In October 2008, we informed Ofgem that our mains replacement activity carried 
out within the UK's West Midlands Alliance partnership may have been 
misreported. National Grid and Ofgem jointly appointed Ernst & Young to carry 
out a full investigation to determine the extent of the issue. At present it is 
too early to determine the likely outcome of the investigation and any potential 
consequences. 
 
 
In May 2007, KeySpan received a civil investigative demand from the Antitrust 
Division of the United States Department of Justice (DoJ), requesting the 
production of documents and information relating to its investigation of 
competitive issues in the New York City electricity capacity market prior to the 
Company's acquisition of KeySpan. The civil investigative demand is a request 
for information in the course of an investigation and does not constitute the 
commencement of legal proceedings, and no specific allegations have been made 
against KeySpan. In April 2008, KeySpan received a second civil investigative 
demand in connection with this matter. KeySpan believes that its activity in the 
capacity market has been consistent with all applicable laws and regulations and 
it continues to cooperate fully with the investigation.  Since July 2009, 
KeySpan and the DoJ have entered discussions that could potentially lead to a 
settlement of this matter.

Independent review report to National Grid plc 
 
 
Introduction 
We have been engaged by the Company to review the condensed set of financial 
statements in the half-yearly financial report for the six months ended 30 
September 2009, which comprises the consolidated income statement, statement of 
comprehensive income, balance sheet, statement of changes in equity, cash flow 
statement and related notes. We have read the other information contained in the 
half-yearly financial report and considered whether it contains any apparent 
misstatements or material inconsistencies with the information in the condensed 
set of financial statements. 
 
 
Directors' responsibilities 
The half-yearly financial report is the responsibility of, and has been approved 
by, the directors. The directors are responsible for preparing the half-yearly 
financial report in accordance with the Disclosure and Transparency Rules of the 
United Kingdom's Financial Services Authority. 
 
 
As disclosed in note 1, the annual financial statements of the group are 
prepared in accordance with International Financial Reporting Standards (IFRSs) 
as adopted by the European Union. The condensed set of financial statements 
included in this half-yearly financial report has been prepared in accordance 
with International Accounting Standard 34, 'Interim Financial Reporting', as 
adopted by the European Union. 
 
 
Our responsibility 
Our responsibility is to express to the company a conclusion on the condensed 
set of financial statements in the half-yearly financial report based on our 
review. This report, including the conclusion, has been prepared for and only 
for the company for the purpose of the Disclosure and Transparency Rules of the 
Financial Services Authority and for no other purpose. We do not, in producing 
this report, accept or assume responsibility for any other purpose or to any 
other person to whom this report is shown or into whose hands it may come save 
where expressly agreed by our prior consent in writing. 
 
 
Scope of review 
We conducted our review in accordance with International Standard on Review 
Engagements (UK and Ireland) 2410, 'Review of Interim Financial Information 
Performed by the Independent Auditor of the Entity' issued by the Auditing 
Practices Board for use in the United Kingdom. A review of interim financial 
information consists of making enquiries, primarily of persons responsible for 
financial and accounting matters, and applying analytical and other review 
procedures. A review is substantially less in scope than an audit conducted in 
accordance with International Standards on Auditing (UK and Ireland) and 
consequently does not enable us to obtain assurance that we would become aware 
of all significant matters that might be identified in an audit. Accordingly, we 
do not express an audit opinion. 
 
 
Conclusion 
Based on our review, nothing has come to our attention that causes us to believe 
that the condensed set of financial statements in the half-yearly financial 
report for the six months ended 30 September 2009 is not prepared, in all 
material respects, in accordance with International Accounting Standard 34 as 
adopted by the European Union and the Disclosure and Transparency Rules of the 
United Kingdom's Financial Services Authority.

1 Business performance results are the primary financial performance measure 
used by National Grid, being the results for continuing operations before 
exceptional items, remeasurements and stranded cost recoveries. Remeasurements 
comprise gains or losses recorded in the income statement arising from changes 
in the fair value of commodity contracts and of derivative financial instruments 
to the extent that hedge accounting is not achieved or is not fully effective. 
Stranded cost recoveries are costs associated with historical generation 
investment and related contractual commitments that were not recovered through 
the sale of those investments - these recoveries end in 2011. Further details 
are provided in Note 3 on page 20. A reconciliation of business performance to 
statutory results is provided in the consolidated income statement on page 11. 
2 Operating cash flow from continuing operations before exceptional items, 
remeasurements, stranded cost recoveries and taxation. 
3 Adjusted to reflect scrip dividend, refer to note 6 on page 22. 
4 'Constant currency basis' refers to the reporting of the actual results 
against the prior period results which, in respect of any US$ currency 
denominated activity, have been translated using the average US$ exchange rate 
for the six months ended 30 September 2009, which was $1.55 to GBP1.00. The 
average rate for the six months ended 30 September 2008 was $1.92 to GBP1.00.
