Magnum fields offers on 160-MW of compressed air storage capacity in Utah

Magnum Compressed Air Energy Storage (MCAES) on Nov. 4 announces a 40-day, non-binding request for information (RFI) regarding its compressed air storage facility located near Delta, Utah.

Compressed air energy storage (CAES) is a bulk energy storage technology designed to enable excess energy from renewable wind and power sources to be stored in commercial-scale solution mined caverns and dispatched back to the grid when it is needed. In that way, it operates something like pumped storage hydro and battery storage. The non-binding RFI begins at 8 a.m. (Mountain Standard Time) on Nov. 7, and concludes at 5 p.m. (Mountain Standard Time) on Dec. 16.

The first MCAES project consists of 160 MW of compression to store air in an underground cavern, with a 160-MW turbine generator.  The current design will use up to 160 MW of renewable electricity to compress air and store it in a deep underground salt cavern. The energy will be returned to the grid, through a 160-MW natural gas-fueled generator, which, when augmented by compressed air, will have a heat rate of about 4227 MMBtu/MWh. The volume of the salt cavern at approximately 4 million barrels will allow the generator to operate for 48 hours before cavern recharging is required. This results in approximately 7,680 megawatt-hours (MWh) of storage from one cavern charge. Also, because the two major industrial components of CAES technology can run independently, the project can provide up to 317 MW of ancillary services to the grid. The equipment would be from Dresser-Rand.

MCAES said its compressed air energy storage project will support the Western U.S. region’s aspirations and goals to deploy ever-higher percentages of cost effective renewable energy. The project is designed to allow renewable projects to cost effectively meet, and even exceed, these sustainable energy ambitions.

“Because of our project’s location and operational capabilities, several renewable project developers have approached us to discuss a collaborative approach in providing an enhanced renewable energy offering to Western utilities,” said Richard Walje, CEO of Magnum CAES. “Instead of waiting for the industry to evolve, Magnum is taking the bold initiative to collaborate with one or more renewable energy developers to support the development of utility scale renewable energy integrated with storage.

An RFI overview and other information can be found on the MCAES website at http://westernenergyhub.com/caes.php.  A completed MCAES Request for Information Form should be emailed to Richard Walje at rwalje@westernenergyhub.com by 5 p.m., Mountain Standard Time, on Dec. 16. For further information call Walje at (801) 993-7001.

Magnum Compressed Air Energy Storage is wholly owned by Magnum Development LLC, a Haddington Ventures LLC portfolio company. Haddington principals have been involved in energy storage businesses since the early 1990s.
