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.
As US states work to address and enable the swift growth of distributed energy resources (DERs), including solar and energy storage, the issues surrounding their interconnection to the electric grid require close attention, Sara Baldwin, VP for regulatory affairs at the Interstate Renewable Energy Council (IREC), explains.
Approval given to a 500MW (AC) solar farm project, co-located with 250MW / 1,000MWh of battery energy storage from renewables developer EPS Energy.
The capabilities of virtual power plants (VPPs) to provide capacity as well as frequency regulation services to the grid in Australia will be demonstrated through a new integration trial.
Expert briefing held six weeks before the Brexit deadline explores strategies for UK energy players to counter price volatility under a no-deal scenario
Uncertainty persists around the impact bankruptcy proceedings brought about at investor-owned utility Pacific Gas & Electric (PG&E) could have on renewables contracts and energy storage projects as it faces “extensive litigation” and “significant liabilities” for California wildfires.
The potential for a 400MW/2,500MWh pumped hydro energy storage site is being investigated in Dubai.
Finland-based power firm Wärtsilä, which is active in the renewable energy and energy storage markets, plans to enter the Indian energy storage market, citing “looming” grid management challenges in the country.
Over €12 million (US$13.18 million) in funding will be provided to two European projects to examine and exploit synergies between the stationary energy storage and transport sectors, through the EU’s Connecting Europe Facility (CEF) funding instrument.
Energy storage and interconnection are complementary technologies, as a means of adding flexibility and keeping costs down in electricity grids, an expert from Fraunhofer ISE has said.
Holland’s national grid operator has said that batteries will be an “excellent alternative” to conventional power plants in providing balancing services, especially as a complement to increased solar and wind deployment.
