aps customers save $6 million in first quarter of eim participation
as anticipated, regional market results in efficiencies and savings
PHOENIX – APS customers have saved $5.98 million from the company’s
participation in the Energy Imbalance Market (EIM), according to a new report
released from the California Independent System Operator. The report analyzed
cost savings from October through December 2016, APS’s first three months of
participation in the western market.
“One of the main reasons we decided to participate in the Energy
Imbalance Market was because of the potential for savings through the
innovative and flexible new tools it provides,” said Tammy
, Vice President of Resource Management for APS. “We are always
looking for ways to save our customers money and, as anticipated, the EIM is
providing us that opportunity.”
The EIM enables utilities across the western region to buy and sell
energy more efficiently. The difference between participating in the EIM over
traditional energy markets is that the EIM automatically finds the most
efficient energy resources available if APS decides to buy or sell power in five
minute increments. EIM’s real-time market capabilities help APS respond quickly
to variable renewable energy production (like solar) and better incorporate
renewable resources by automatically adjusting to intermittency.
