Goldman Sachs Renewable Power has acquired a 100MW solar PV plant with a 50MW battery storage facility currently under development in San Bernadino, California.

A newly released standard creates nationally applicable guidance for DER manufacturers on how grid support functions in their products will be tested. Brian Lydic, chief regulatory engineer at the Interstate Renewable Energy Council (IREC), talks about what this means for enabling the grid modernisation that will be needed to support high levels of renewable energy and energy storage.

The US Federal Energy Regulatory Commission (FERC) hosted a technical conference on hybrid resources – pairing storage with generation – examining in order to overcome barriers that exist to the otherwise fastest-growing phenomenon of the grid.

A new project is underway in the US to tear down a significant barrier for “realising the full benefits” of energy storage: the complexity and lack of clarity over interconnection rules across the country.

With a quarter of all solar project proposals in the US including batteries, transmission grid operators across the country are taking a variety of steps to evaluate the role that can be played in wholesale electricity markets by hybrid power plants – defined as generation coupled with energy storage.

Realising the theoretical promise of solar-wind-storage hybrids is far from straightforward, with individual projects likely to vary considerably. Ben Willis examines some of the technical complexities of combining different technologies into a single, profitable entity.

As more US states take steps to ensure energy storage can be integrated on the grid and contribute to the achievement of aggressive clean energy goals, the implementation details are critical, says Sara Baldwin of the Interstate Renewable Energy Council (IREC)

As we move into a new decade, the question is whether the burgeoning US energy storage industry will be able to maintain its current path of rapid growth. All signs suggest that it will, argues Ricardo F. Rodriguez of Navigant Research.

Developer NRStor and technology provider Hydrostor have completed work on a multi-megawatt, commercial, advanced compressed air energy storage (A-CAES) system in Canada.

Even the US states leading in energy storage market development still have work to do when it comes to adopting the best and lowest-cost grid interconnection procedures, an expert in regulatory affairs at the Interstate Renewable Energy Council (IREC), has said.
