Utility-Scale Storage Critical to Achieving Massachusetts Carbon Goals: UMass Study

The Commonwealth of Massachusetts is likely to fall short of its greenhouse gas emission goals if it cannot implement utility-scale storage, according to a new study. More than 70% of the state’s two pumped-hydro storage facilities — with a collective capacity of around 1,800 MW  is currently unutilized due to the lack of market incentives, according to researchers. The lack of utility-scale storage could mean that the state’s grid remains “dirty” even with a high penetration of renewables. 

Is Energy Storage Finally Ready To Tackle the Wind Sector’s Biggest Challenge?

Now that wind energy has gone mainstream, the big challenge is how to squeeze the most kilowatts out of a wind turbine. The task is more complicated than simply increasing the size and efficiency of the turbine. People—and businesses—need electricity when they need it, but the wind blows when it will. The result can be an undersupply of wind energy during peak demand periods and an oversupply at other times, especially at night. However, more economical energy storage technology is coming online, and it’s having a powerful impact on both the wind and solar energy markets.

NIPSCO to Replace Coal with 2.3 GW of Solar, Storage in Latest RFP

The Northern Indiana Public Service Company (NIPSCO) announced on Oct. 1 a request for proposals for 300 MW of wind, 2,300 MW of solar and solar-plus-storage projects, as well as an undefined amount for other capacity resources.
NIPSCO seeks to retire the bulk of its coal generation capacity by 2023, and its October 2018 Integrated Resource Plan identified cheaper alternatives in renewables paired with storage.

Battery System to Provide Frequency Regulation for PJM

A 72 MW/72 MWH battery system owned by a global independent power producer is expected to soon start providing grid services in PJM territory, signaling the storage industry’s increasing maturation and ability to compete with traditional resources. Industry supporters have argued that getting more storage online to support renewables integration and provide other grid benefits would require compensation schemes that allow storage to compete.

Enabling Versatility: Allowing Hybrid Resources to Deliver Their Full Value to Customers

Hybrid resources are growing dramatically. Energy storage-paired generators offer enhanced capabilities and can respond to economic signals differently than traditional generator resources. Yet, many grid planning rules overstate the cost of interconnecting hybrid resources, and operating rules unduly limit the flexibility and other services that these resources can provide. Industry practices, market rules, and regulations need to be updated to remove barriers to entry and allow these resources to offer their full value to the power system, which will enhance market competition and ensure just and reasonable rates.

Power Plants with Energy Storage Can Boost Electric Market Competition and Lower Costs

As electricity markets innovate with new technologies to increase system reliability and efficiency, a new industry white paper released today shows how energy storage projects integrated with power plants, such as wind and solar power, are crucial to providing greater value to the electric grid, facilitating greater market competition and lowering electricity costs for consumers. The white paper, entitled Enabling Versatility: Allowing Hybrid Resources to Deliver Their Full Value to Customers, is the product of a collaboration between Grid Strategies and the U.S. Energy Storage Association.

APS Issues RFPs for Solar and Wind Energy Resources

Arizona Public Service Co. (APS) issued two separate Requests for Proposals (RFPs) for solar and wind resources. These RFPs will help expand the company’s renewable energy portfolio to approximately 2,500 megawatts by 2021 – enough to power more than half a million Arizona homes. Projects must employ commercially proven technology and must be designed with the flexibility to add energy storage as a future option.

UA Initiates 100% Clean Energy Project with TEP

By partnering with Tucson Electric Power for the purchase of solar and wind power, the University of Arizona will offset all of its scope two greenhouse gas emissions with green energy by December 2020. Under the agreement, TEP will dedicate portions of two new renewable energy projects to serving the energy needs of the University of Arizona, including a wind farm in New Mexico and a solar-plus-storage system southeast of Tucson.
