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.

Hawaiian Electric Seeks Bids for 900MW of ‘Dispatchable Renewables,’ Storage, and Grid Services

Hawaiian Electric has issued a long-awaited request for proposals (RFP) for about 900 megawatts of renewable energy and energy storage projects. It’s the utility’s second major round of contracts in the past year seeking to marry variable solar and wind power with the capacity and flexibility of batteries. HECO’s new RFPs are broken into a number of specific projects and specific needs across its three islands, with a mix of different technologies required. This complexity comes from the fact that these RFPs have been structured to help replace two big fossil fuel-fired power plants to close in the next five years

GlidePath Acquires 149MW Texas Wind Portfolio with Storage Additions Planned

GlidePath Power Solutions has acquired eight wind projects in North Texas with a total capacity of 149MW. The portfolio, purchased from Exelon Generation, will be optimised by GlidePath while it plans how best to add energy storage on-site at each project. The projects are all north of Amarillo and sell into the Southwest Power Pool (SPP). According to GlidePath, they will be the first battery storage projects in the SPP.

North Sea Rocks Could Act as Large-Scale Underwater Renewable Energy Stores, Study Finds

Rocks at the bottom of the North Sea may provide the perfect storage location for renewable energy, according to a new study. Excess power could be stored in the form of compressed air inside porous formations on the seabed, providing a reservoir that can provide energy on demand. This pressurized air can be released to drive a turbine, generating a large amount of electricity. This would allow green energy to be stored in summer and released in winter, when demand is highest.
