Recommendations on how batteries can modernize the US grid system have been set out in a white paper published on July 18 by Gridwise Alliance, a company representing stakeholders that design, build and operate the electric grid.
Clarification in policy, services and asset classification are needed to ensure energy storage systems are fully utilized in North America’s transition to a de-carbonized future, the white paper, titled ‘Advancing Batteries to Enhance the Electric Grid Chapter One: Front-of-Meter Applications’ found.
The paper concluded that batteries were uniquely versatile grid modernization assets, which could help advance a reliable, resilient, affordable, and sustainable electric system as increasing amounts of renewables, whether wind or solar, come on stream.
Steve Hauser, CEO of the alliance, said: “Our organization has always been at the forefront of key conversations related to grid modernization. Today, one of those key conversations centres on batteries. This whitepaper enables our uniquely diverse membership to inform that conversation in the states and at the national level.”
Yet despite declining costs and technological advances, numerous obstacles remain to wide-scale implementation of economic battery projects.
The white paper stated: “As often happens with rapidly evolving new technologies, existing cost mechanisms, regulations, market rules and policies have not kept pace with recent technological advances in batteries and do not reflect the multiple potential benefits highly flexible and versatile assets can offer to maximize the benefits batteries can provide to the grid and to society, policy makers should re-examine existing policies and modify or create new ones as needed.”
Among the various battery technologies, lithium-ion is seen as offering the greatest value for the foreseeable future, according to a recent report by GTM. This is in part because of the technology’s wide range of services, ease of deployment, permit and finance.
Economies of scale make lithium-ion adoption more cost effective, its use set to increase from its 2016 standing, which saw around 97% of the US’s 280MW of utility-side ESS deployment using the chemistry, lead-acid, in comparison, took just 2.7% of the market, said the report.
Distribution operator UK Power Networks announced on January 23 it is to launch four vehicle-to-grid (V2G) projects to demonstrate how electric vehicles can be used for peak shaving and possibly deferring reinforcement costs. The projects, in the south east and east of England as well as London, will look at how the technology can read more
US energy storage firm ViZn Energy Systems has appointed Stephen Bonner as the president and interim CEO of the zinc iron flow battery, the company announced on January 26. Bonner, who was named chairman of its board of directors on January 1, assumed the additional roles following the resignation of Ron Van Dell, who read more
Installations of PV plus battery systems have risen by 1,830% on the Hawaii island of Oahu helped in part to falling prices, according to a report from the state’s department of business economic development and tourism released on January 31. The report, based on building permit data released by the Honolulu Department of Planning read more
Energy storage start-up Arenko announced on February 5 that it had chosen General Electric to deliver a 41MW lithium ion energy storage system to ensure security of supply to 100,000 UK homes. The strategic alliance will combine GE’s technology with London-based Arenko’s experience of the UK market as well as its proprietary energy trading read more
South Australia’s adoption of the latest technology to address its energy problems will involve a trial of virtual power plants and installation of a 4.3MWh lithium ion micro-grid, its government announced in early February. The state’s energy minister Tom Koutsantonis said the South Australian Produce Market would install 2.5MW array using 1,600 solar panels read more
