EnerKnol’s Visual Primer – States Make Strides in Setting Pay Outs for Battery Storage, Opening Door to Growth

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.

PacifiCorp Proposes $22 Million Portfolio of Innovative Programs to Enhance Grid Management

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…

FERC Approves Reforms to Enhance Battery Storage Participation in New England Wholesale Power Markets

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…

California Approves Battery Installation to Provide Black Start Service at Gas-Powered Plant

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…

Massachusetts Regulator Unveils Framework for Capacity Rights in Solar Incentive Programs

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…

Liberty Utilities Wins Approval for Customer-Sited Battery Pilot in New Hampshire

The New Hampshire Public Utilities Commission on Jan. 17 authorized Liberty Utilities Co. to install up to 500 Tesla Powerwall 2 batteries behind the meter at customers’ premises under a pilot program intended to achieve customer savings through peak load reductions. Liberty said that the initiative marks the first program in the nation to combine…

Hawaiian Electric Proposes Largest Portfolio of Solar-Plus-Battery Projects at Record Low Prices

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…

Greater Regulatory Clarity Will Facilitate Fair Competition of Storage Resources in Ontario Power Market: Report

The Ontario Independent Electricity System Operator issued a report on Dec. 20 identifying obstacles and mitigating strategies to ensure that energy storage resources can be integrated into its market and can compete in the delivery of services when feasible. The report calls for clarity in the market rules, Ontario Energy Board codes, and legislation and…

State Commitments to Procure Energy Storage Exceed 5.3 Gigawatts

States have started to build the foundation for a future of battery storage to capitalize on the multiple benefits the technology provides to the grid, from helping integrate renewables to bolstering the reliability of the network. State legislatures are boosting the number and diversity of measures proposed to stoke storage markets, considering a broad array…

EnerKnol’s Visual Primer – California’s 100 Percent Zero-Carbon Goal Hinges on Energy Storage

California has enacted legislation that reinforces the state’s clean energy leadership with a goal of procuring 100 percent of the state’s electricity from renewable and zero-carbon resources by 2045. California’s move is historic in that it represents the world’s fifth-largest economy having established a renown in the international climate arena. The Golden State has accelerated the growth of its solar and wind industries but success likely depends on whether storage systems can supplant natural gas that provides about a third of the state’s electricity. Earlier this year, California became the first U.S. state to mandate solar rooftop panels on new homes. To achieve its 2030 goal of five million zero emission vehicles, California recently enacted a law to assess charging infrastructure buildout.

EnerKnol Insights – How Falling Costs and Evolving Grid are Accelerating Battery Deployment

The convergence of technologies, markets, rate design changes, and business models is unleashing new opportunities in the emerging electricity storage sector. Energy storage can provide multiple services at the same time or with the same resource, providing operational flexibility as the system becomes decentralized and decarbonized. While storage provides undeniable benefits in grid-connected solutions and flexibility, market mechanisms and rate designs will play a critical role in scaling up deployment. State policies that pair distributed generation with storage provide further avenues for growth.

EnerKnol’s Visual Primer – Battery Storage Catching up to Natural Gas as a Peaking Resource

Growing large-scale deployments of energy storage systems, driven by declining costs and evolving technology, has opened an opportunity for these systems to compete with traditional natural gas peaker plants. Standalone storage makes for a resource-agnostic solution that would enable utilities to charge up as required using the available energy mix. As improvements in technology allow battery systems to provide power for longer periods, utilities will benefit as they must manage a growing share of renewables while meeting peak demand.
