The US Energy Department’s National Renewable Energy Laboratory (NREL) has selected the RESolve energy storage system from Renewable Energy Systems (RES) for an energy storage test project.

In this connection, a 1MW/1MWh energy storage test project will be carried out at NREL’s National Wind Technology Center (NWTC).

The test project is expected to be completed in April. Following which, NREL researchers will use the 10-plus demonstrated RESolve applications to evaluate specific modes ranging from frequency regulation and renewable energy integration, to “black start” and seamless grid-to-island transition among more advanced modes.

RES chief technology officer Dr. Andy Oliver said: “RES is pleased to install its sixteenth system (our 147th megawatt) near our home in Denver.

“RES is looking forward to supporting NREL in their renewable integration efforts with our grid-ready storage product.”

The company has collaborated with LG Chem on battery supply for the energy storage system. To deliver the power conversion system (PCS) unit, it has partnered with SMA.

For the installation of the pad mount transformer, RES has worked with Siemens.

Headquartered in the UK, RES is a technology-agnostic integrator which provides engineering, procurement, and construction (EPC) and also provides long-term performance wraps.

In May last year, RES had signed a 4-year contract to deliver 20MW power to the UK National Grid in a fraction of a second after the detection of deviation in frequency. For this purpose of supporting grid balancing, RES will deliver a battery storage system which is likely to commence operations in mid 2018.

The energy storage company had previously commissioned six battery storage projects across North America.
