In the spirit of harnessing clean energy and enhancing grid reliability, Californian utility San Diego Gas & Electric (SDG&E) has signed contracts for 83.5MW of energy storage.

Projects that demonstrate how energy storage can benefit a wide range of stakeholders and the electric grid can compete for US$15.5 million of funding from the New York State Energy Research and Development Authority (NYSERDA).

Clearly, renewable energy is now a viable alternative to traditional generation from a cost perspective. However solar and wind’s penetration of the grid is constrained by ageing infrastructure, high grid connection costs and their intermittent, weather-dependent nature. Scott McGregor looks at how long-duration energy storage on an industrial scale can help.

Energy storage companies “have suffered significant and detrimental harm” from changes to rules governing the frequency regulation market in US regional transmission organisation (RTO) PJM Interconnection’s service area, the Energy Storage Association has said.

One of Australia’s energy market regulators has put out a lengthy document detailing the potential impact of introducing five minute settlement into the electricity spot market, which would likely favour flexible resources such as energy storage.

Maryland will become the first state in the US to offer tax credits for customer-sited energy storage, as and when state Governor Larry Hogan approves Senate Bill 758 (SB 758).

California’s Self-Generation Incentive Program (SGIP), the scheme to incentivise the use of distributed energy, opens for applications at the beginning of next month, weighted to favour energy storage.

A new report from the US National Renewable Energy Laboratory (NREL) aims to track cost trends in residential PV-plus-storage, help stakeholders to identify potential cost-reduction opportunities and illuminate barriers that exist to the technology’s widespread deployment.

Solar Media’s Energy Storage Summit took place at the end of February and was attended by around 350 delegates and stakeholders, looking at energy storage markets in the UK and beyond. Collected here are seven interviews with leading figures at the event spanning utility-scale, commercial and residential energy storage.

Arguing that energy storage is “critical to ensuring a resilient, reliable, cost-effective and sustainable grid”, the Energy Storage Association joined with 52 other organisations to plead the place of storage in the Trump administration’s infrastructure priorities.
