The US state of Tennessee is set to join the advanced energy storage age with the deployment of a 40MWh stationary grid-connected battery storage plant.

Public utility NV Energy has announced plans to build three solar parks with battery storage and a large-scale transmission line project in Nevada, as it looks to transform the state’s clean energy landscape.

Arizona utility Tucson Electric Power (TEP) has set out plans to provide 70% of its power from solar and wind by 2035, backed up with investment in new energy storage capacity.

The US national Energy Storage Association’s policy director, Jason Burwen, spoke with Andy Colthorpe about the seven early adopter states of energy storage targets and whether this is likely to be a spreading pattern across the country.

In light of Virginia’s goal to go 100% renewable and clean energy by 2050, utility Dominion Energy has issued a Request for Proposals (RFP) for 1,000MW of onshore wind and solar and up to 250MW of energy storage as well as laying out longer-term plans.

An optimal power system portfolio for the US state of California that would drive the world’s fifth largest economy towards greenhouse gas reduction goals for 2030 and then to zero carbon by 2040, includes 1GW of long duration energy storage.

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.

Despite making huge strides forward, the energy storage industry’s work in helping stakeholders across the value chain understand the technologies and the roles they can play in a renewable energy future is far from done. Andy Colthorpe speaks with Energy Storage Association chief executive, Kelly Speakes-Backman, at the forefront of the industry’s push into unchartered regulatory, policy and public affairs matters.

PacifiCorp has formalised a long-anticipated shift from coal to solar, wind and battery storage, setting ambitious targets underpinned by a belief in clean energy’s sound economics.

Utility NV Energy has awarded contracts in the US state of Nevada for over 1,000MW of renewable energy projects – including a 420MW-dc solar farm – and has also requested approval for 100MW of energy storage.
