> (Bloomberg) --
> Southern California Edison is embracing energy-storage technology over the natural gas-fired peaker plants that utilities have traditionally relied upon to meet sudden shortfalls in electricity.
> “If the requirement is just, ‘Hey we’re just short energy or capacity,’ then yes, energy storage is going to be the solution before probably a peaker,” Colin Cushnie, vice president of energy procurement and management, said in an interview at the utility’s office in Rosemead, California. “We don’t want to put peakers on the grid if cleaner-cost options are available.”
> The shift to
> storage is a sign that the systems are becoming more affordable. Battery facilities are also smaller, more flexible and easier to expand than peaking power plants. Gas-fired peakers also sometimes face significant community and regulatory resistance in California.
> Peak Demand
> Peakers discharge power when needed during peak-demand periods. Batteries can do that and more, Cushnie said.
> “Batteries can also meet peak demands with lower emissions than natural gas-fired peakers by charging during low-demand periods when excess wind and solar energy is being generated, and discharging during peak demand periods, which displaces the need to burn incremental natural gas in a peaker,” he said.
> Southern California Edison has contracts for more than 275 megawatts of storage capacity from suppliers that include AES Corp. and Advanced Microgrid Solutions LLC. It plans to solicit as much as 120 megawatts of additional capacity in 2016.
> Regulators have asked California’s three biggest utilities to line up 1.3 gigawatts <http://energy.gov/sites/prod/files/2014/06/f17/EACJune2014-3Charles.pdf> of storage capacity by 2020, and set a target of 580 megawatts for Southern California Edison. That may come from batteries or other technologies.
> While Southern California Edison recognized the merits of batteries, the Edison International unit was initially skeptical that storage could be cost effective when California announced the storage mandate in 2013.
> Southern California Edison solicited its first storage deals later that year, seeking about 50 megawatts of capacity. When the bids turned out to be more affordable than expected, the company signed procurement contracts for more than 260 megawatts.
> ‘Competitive’ Prices
> “We knew it was technically feasible,” Cushnie said. “When prices came in, we saw it was competitive.” He declined to provide terms of the contracts.
> Southern California Edison fielded more than 1,000 storage bids with a wide range of prices and functions for the first procurement. The cheapest proposals indicate that developers expect costs to fall by the time the projects are expected to go into service. Some emerging storage technologies include standard lithium-ion batteries, liquid metal <> and ice <>.
> “People just brought everything and dumped it on the table,” Cushnie said of the initial procurement. “There were a lot of fliers thrown at us.”
> The range of prices and types of technologies bid has since begun to narrow, a trend Cushnie said he noticed in the company’s second procurement <http://tinyurl.com/hlb7445> for storage, when it selected 16.3 megawatts of capacity in September.
> “There was more of a standardization among the technologies that was submitted,” he said. “People were figuring out, ‘This is what they’re looking for, this is what they’re buying.’”
