ENERGY STORAGE
A growing number of states across the U.S. are amping up energy storage to complement the drive towards clean energy as batteries can help integrate diverse generation technologies and stabilize the grid. State commitments to procure battery storage capacity now top 11 gigawatts, following targets established by Nevada and Virginia this year.
More U.S. states are exploring programs and policies to leverage the application of battery storage for the benefit of the power grid and to examine how the technology may provide value to consumers. Studies and investigations are intended to help craft initiatives that can tap the resource for multiple applications ranging from offsetting peak loads, supporting renewable integration and stabilizing the distribution system, to providing peaking capacity and replacing fossil generation.
Battery storage has long held the promise of eventually replacing the costliest, most-polluting fossil-fuel fired generators that are used to meet surging electricity demand on the grid. That day may now be upon us as costs of batteries plummet and as state regulators from Massachusetts to Arizona weigh new incentives for the technology.
Battery storage is no longer just paving the way for greater integration of renewables onto the grid. The technology is now ushering in larger utility-scale solar and wind projects with diverse configurations. Utility proposals to develop massive storage projects in tandem with renewables are becoming more common as intermittent wind and solar continue to produce a growing share of power generation. Aggressive state and utility decarbonization goals are also driving the need for cost-effective batteries.
Rep. Michael Doyle, a Democrat representing Pennsylvania, introduced legislation on April 4 that would expand the solar investment tax credit to include energy storage technology for utilities, businesses, and homes. The current tax code provides the credit for battery technologies paired with a solar installations. (H.R.2096) More than 100 House Democrats, led by Congresswoman Haley…...
The Maryland legislature on March 28 approved a measure that would extend the state’s community solar pilot through 2024 and remove the limit on the maximum number of subscribers in the program. The legislation would also include annually increasing capacity levels for each program category, modifying the current requirement that allows restrictions to enable regulators…...
U.S. states are plowing ahead in setting market compensation rules for battery technology, laying the foundation for future growth of the fast-maturing technology in retail and wholesale markets. While progressive states California, New York and Massachusetts are charging ahead in how to value the resource, others are still grappling with how to regulate a system that fails to fit squarely in any one box and that raises a range of jurisdictional and ownership questions.
Rocky Mountain Power, a division of PacifiCorp, proposed three innovative utility programs to explore vehicle-to-grid power flow management, study the value of behind-the-meter grid optimized solar-plus-battery installations, and improve outage response by deploying line sensor technology on distribution circuits, according to a March 8 filing with the Utah Public Service Commission. The initiatives form the…...
The Federal Energy Regulatory Commission on Feb. 25 accepted ISO New England Inc.’s market rules to enable advanced storage technologies to be dispatched and priced in the real-time energy market in a manner that more fully recognizes their ability to transition rapidly between charging and discharging. The revisions allow batteries and emerging storage technologies to…...
The California Energy Commission on Feb. 20 approved the installation of a battery storage system to the Russell City Energy Center, a 600-megawatt natural-gas fired power plant, to provide black start capability. The project consists of installing 6 to 10 megawatts of lithium-ion batteries, which would be used to start the gas turbines, in order…...
The Massachusetts Department of Public Utilities issued an order on Feb. 1 clarifying ownership of capacity and energy rights of facilities under net metering and Solar Massachusetts Renewable Target, or SMART, programs participating in the ISO New England Inc.’s forward capacity market. The order allows owners of storage-paired facilities to retain their energy or capacity…...
The Hawaiian Electric Companies submitted power purchase agreements for seven grid-scale, solar-plus-storage projects to the Hawaii Public Utilities Commission, according to a Jan. 3 press release. The projects total 262 megawatts of solar and 1,024 megawatt-hours of energy storage, with contract prices ranging from $0.08 to $0.12 per kilowatt-hour. The utilities said that the contracts…...
