The ISO is a nonprofit public benefit corporation that manages the bulk electric market, and the flow of electricity over the high-voltage, long-distance power lines for California and a small part of Nevada.

EIM hits record benefits, lower GHG emissions

EIMRecordHighs

The Western Energy Imbalance Market (EIM), California ISO’s real-time electricity market, reported benefits totaling more than $71 million during the second quarter of 2018, the largest single-quarter savings since the market opened in 2014.

The previous quarterly high of $42 million was set in first three months of 2018. Since launch in November 2014, total gross benefits from the energy market have totaled $401.73 million.

The EIM optimizes resources to find the lowest cost resources to serve demand across the western United States. The ISO’s sophisticated, automated software allows use of existing resources and transmission lines to create benefits. The EIM also provides more opportunity to meet demand by using excess renewable energy. Carbon emissions decreased by 306,112 metric tons – the equivalent of taking nearly 65,000 cars off the road for a year – since the market launched.

The current EIM participants include Arizona Public Service, California ISO, Idaho Power, NV Energy, PacifiCorp, Portland General Electric, Powerex, and Puget Sound Energy. Five more utilities are planning to join the real-time market in the next three years.

Consumers saved 1,000 MW during heatwave

FlexAlert

The ISO thanks Californians for answering the call to conserve electricity during two statewide Flex Alerts issued on July 24 and 25. Flex Alerts are calls to consumers to voluntarily reduce electrical use during periods when the grid is stressed.

Californians were asked to take energy saving measures, such as setting air conditioner thermostats to 78 degrees or higher, delaying use of major appliances, unplugging electric vehicles, and turning off unnecessary lights until after 9 p.m.

Conservation efforts proved more impressive than ever. According to ISO estimates, consumers reduced demand by a total of 990 megawatts, which helped grid operators stabilize the system during two days of high electrical demand.

The ISO has relied on consumer participation for nearly two decades and appreciates the California residents and businesses heeding the call to reduce electrical use.

ISO awarded at Intersolar Europe 2018

Award

In a breakthrough that could open the door to improved grid management of green energy, the ISO, First Solar and the National Renewable Energy Laboratory (NREL) received the inaugural Smarter E Award for an Outstanding Project for work on photovoltaic solar power and grid reliability.

The project tested and demonstrated the effectiveness of highly responsive and essential services for maintaining grid reliability on a 300-megawatt (MW) utility-scale photovoltaic (PV) power plant in California. It proved that renewable resources can be used for ancillary services related to grid stability. The findings can improve management of green energy, allowing grid operators to add more renewables to the system while enhancing reliability.

In the most extensive testing of its kind, the study focused on solar resources performed in three critical areas: frequency control, voltage control, and ramping capability. The North American Electric Reliability Corp. (NERC) identified these areas as essential for reliability services in expanding renewable resource integration into the power grid.

The award was presented on June 22 in Munich, Germany at the InterSolar Europe 2018 conference.
