Appalachian Power Touts "Largest of its Kind" Pumped Energy Storage (Ind. Report)
Appalachian Power ,LS Power Development
Date: 2021-02-10
In the Old Dominion State, Duke Energy reports it will acquire 400 MW of energy storage from Roanoke-based Appalachian Power's Bath County Pumped Energy Storage Station in the Allegheny Mountains north of Roanoke.

New York-headquartered LS Power Development holds a 24 pct interest in the Bath County Pumped Storage Station which is touted as the "largest of its kind in the world" capable of producing sufficient power for as many as 750,000 homes, according to Dominion Energy.

The Virginia Clean Economy Act, a landmark law passed last year by the General Assembly, requires Appalachian and Dominion to invest in energy storage as well solar and wind in order to meet the state's 100 pct renewable power portfolio by mid-century.

German Utility Plans 4 GW of Renewables Capacity by 2025 (Int'l.)
Uniper
Date: 2020-12-14
Frankfurt, Germany-based utility UNIPER is reporting plans to develop 4 GW of solar and wind power projects beyond 2025, including its business in Russia where the company presently operates fossil-fuel based power stations.

Across Germany, UNIPER owns and operates power plants totaling 10.5 GW. Most of UNIPER's thermal plants use hard coal or natural gas as fuel. UNIPER also owns more than 100 hydroelectric power and pumped energy storage plants in Germany. (Source: UNIPER, Dec., 2020) Contact: UNIPER, www.uniper.energy

Absaroka Montana Pumped Hydro Project Secures Funding (Funding)
Absaroka Energy
Date: 2019-07-17
Bozeman, Montana-based Absaroka Energy reports it has secured financing for a planned 400 MW pumped hydro project near Martinsdale, Montana, through an equity investment from Denmark's Copenhagen Infrastructure Partners (CIP).

The $1 billion closed loop Gordon Butte Pumped Storage Hydro project, which previously secured construction and operation permits from FERC, is designed to help integrate more renewable energy onto the Pacific Northwest electrical grid and could start work in 2020. GE Renewable Energy will supply the pump and turbine equipment for the project.

Snowy Hydro Expanding Pumped Hydro Energy Storage Capacity (Int'l)
Snowy Hydro
Date: 2018-12-14
In the Land Down UNder, Cooma, NSW-based Snowy Hydro Limited reports its board has approved a final investment decision to proceed with the proposed Snowy 2.0 pumped-storage hydro expansion, subject to shareholder approval.

Snowy 2.0, a pumped-storage hydro expansion of the existing Snowy Scheme, will provide as much as 2,000 MW of on-demand electric power generation and 350,000 MWh of large-scale energy storage at an expected cost of $4.5 billion.

Snowy Hydro owns and operates about 5,500 MW of generation capacity, including the Snowy Mountains scheme in Australia. (Source: Snowy Hydro Ltd., Hydro World, 12 Dec., 2018) Contact: Snowy Hydro, + 61 2 6453 2888, info@snowyhydro.com.au, www.snowyhydro.com.au

DOE Selects Pumped Storage Projects for Study (Ind. Report)
US DOE, Energy STorage
Date: 2018-12-05
In Washington, U.S. Department of Energy (DOE) has announced selections for its Notice of Opportunity for Technical Assistance (NOTA) to perform techno-economic studies to evaluate the long-term value of two selected pumped-storage hydropower (PSH) projects. While PSH projects were initially built to balance the electricity system between period of high demand during the day and low demand at night, increases in variable renewable generation have changed how plants are operated and the value they provide to the grid. For example, instead of generating during the day and pumping at night, many plants now change operational modes multiple times per day and are relied on to provide quick ramping or frequency response.

Determining the value of PSH under these changing grid conditions is a significant challenge that requires new modeling tools and analysis. These studies will provide PSH developers with improved capabilities to estimate the value of a proposed PSH project and compare financial revenue streams under current market structures relative to the economic value of PSH projects to the grid.

The techno-economic studies for the two selected projects will be carried out by a Technical Assistance team comprising subject matter experts from the following DOE national laboratories: Argonne National Laboratory, Idaho National Laboratory, National Renewable Energy Laboratory, Oak Ridge National Laboratory, and Pacific Northwest National Laboratory.

The studies will support a larger multi-year research strategy to define the capabilities and estimate the value that hydropower and PSH resources contribute to electric grid resilience and reliability and how those contributions could be optimized for a rapidly evolving grid.

The Technical Assistance team has developed draft guidance -- a step-by-step methodology that can be used by PSH developers, plant owners and operators, and other stakeholders to assess the economic value of existing or planned PSH projects. The methodology will be applied at the two sites below to evaluate and demonstrate the potential economic and financial value of the proposed projects. Through these studies, the team will test and refine the valuation guidance, after which the guidance and valuation tools will be made publicly available for use by the hydropower industry.

GridAmerica Holdings' proposed Goldendale project would be located on the border of Oregon and Washington at the northern terminus of the Pacific AC and DC intertie transmission lines. This project, if constructed, could facilitate the storage and export of the growing amount of wind energy available in the Northwest to nearby states.

Absaroka Energy's proposed Banner Mountain project in central Wyoming along the proposed route of the Energy Gateway West 500-kilovolt (kV) transmission line, which would enable it to serve additional areas in the western and southwestern U.S.. Banner Mountain would be a closed-loop facility that would include three ternary units -- a PSH technology that enables rapid switching between generating and pumping modes -- for a total capacity of 400 MW.
