Customers to benefit from more savings, greater
resource diversity and expanded transmission pathways
Today, Arizona Public Service (APS), Salt River Project (SRP),
Tucson Electric Power (TEP) and UniSource Energy Services announced
plans to join Southwest Power Pool’s (SPP) Markets+, a day-ahead
and real-time energy market that is anticipated to span through the
northwest, southwest and mountain west regions of the U.S. The new
market is expected to bring enhanced reliability and savings of
nearly $100 million above current market participation, passed back
across the electric companies’ customers. It will also support the
addition of more renewable resources to the energy grid, as Arizona
continues to experience residential and business growth and
record-breaking energy demand.
Along with other western utilities, Markets+ is anticipated to
help the Arizona energy providers respond efficiently to market
price changes and regional weather events driving energy usage,
while giving them access to a larger pool of diverse generation
resources. After several years of strategic planning and
development, APS, SRP, TEP and UniSource expect to participate in
the new market as early as 2027.
“Arizona is one of the fastest growing states in the country and
we are thoughtfully planning for the future and evolving our
operations to continue to provide top-tier service and reliability
to our customers at an affordable cost,” said Brian Cole, APS Vice
President of Resource Management. “Together with our neighboring
utilities, APS plans to join Markets+ to efficiently deliver energy
and bolster the resilience of our shared energy grid in Arizona and
across the region.”
“SRP’s participation in SPP Markets+ is a key component of our
plan to meet the growing energy needs of our customers reliably and
affordably and will help us achieve our 2035 Sustainability Goals,”
said Josh Robertson, SRP Director of Energy Market Strategy. “We
look forward to working with utilities in the region to bring the
cost and resilience benefits to our respective customers.”
“Tucson Electric Power and UniSource Energy Services are excited
about the value that Markets+ can provide to our customers,
including cost savings and greater access to clean energy and other
resources that support affordable, reliable service,” said Erik
Bakken, TEP Senior Vice President. “We look forward to
strengthening an already collaborative, productive relationship
with Southwest Power Pool, our reliability coordinator, in its new
role as market operator.”
What is an energy market?
An energy market is an interconnected network of electricity
providers that help meet the supply and demand of power across a
specific geography and include transmission pathways for
electricity to travel from one location to another. Through
Markets+, APS, SRP, TEP and UniSource will have greater access to
substantial cost-effective hydroelectric, wind and nuclear power to
help meet their customers’ needs. When demand is lower, the Arizona
utilities can sell energy, like excess solar power during the
winter season, to maintain a balanced electric system, while also
taking advantage of cost-savings opportunities.
How will Markets+ benefit Arizonans and the region?
Over the past several years, APS, SRP, TEP and UniSource
actively participated in workshops and planning meetings with other
western utilities to equitably develop the new market’s design.
Markets+ offers participants an independent governance structure
that ensures the market meets the needs of customers now and into
the future and provides each utility equitable representation and
voice in the process. The design is intended to offer a variety of
benefits to customers, including:
Increased Reliability
- Participation standards requiring utilities to maintain
specific generation levels to sustain a reliable pool of available
market resources.
- Improving regional energy flows to better serve customer needs
on transmission lines from the Northwest through the Mountain West
and down to the Southwest.
- Efficient market structure that allows energy providers greater
flexibility in meeting customers’ short-term and long-term energy
needs in real time and day-ahead markets. This allows utilities to
plan long-term, the next day, hourly and down to even 5-minute
intervals.
Greater Cost Savings
- Greater savings for customers from more efficient utilization
of generation resources.
More Clean Energy
- Expanded diversity of renewable and clean energy technologies –
from solar power and battery energy storage to wind and hydropower
– expected across a region from Arizona to Canada.
- Support for participating utilities’ clean energy goals by
enabling better movement of clean energy from a shared pool of
power plants and technologies.
- Leveraging Southwest Power Pool’s 20 years of experience as a
regional transmission operator, which includes a recent,
significant expansion of renewable resources.
