Battery-based energy storage could provide up to 13 different services to the US electricity grid, while the usefulness of the technology increases the more ‘distributed’ it is along the system, according to a new report.

Sustainability group Rocky Mountain Institute, which in 2014 merged with Carbon War Room, the climate change combating non-profit group founded by billionaire entrepreneur Richard Branson, issued “The economics of battery energy storage”, last week.

The report examines what services batteries can provide to the grid, where batteries need to be on the grid to deliver each of these services, how much value batteries can generate when performing multiple tasks at high utilisation (known in the industry as ‘benefit stacking’) and finally what barriers exist from allowing batteries to provide those services.

The report is essentially a high-level repurposing or re-reporting of conclusions commonly reported as held by a number of experts within the energy storage industry. At the beginning of this year the largest regulated electric delivery business in Texas, Oncor Electric Delivery, proposed that it should be allowed to install 5,000MW of mostly customer-sited energy storage. Based on a report it commission from consultancy The Brattle Group, Oncor said wholesale markets and transmission and distribution (T&D) systems alike could benefit from the use of storage but that the economics of doing so are prohibiting deployment.

At the time, one energy expert, Melissa C Lott, said the regional electricity transmission and distribution operator’s plan to install energy storage batteries could enable ‘benefit stacking’as a way of overcoming “crippling challenges” faced by energy storage.

Similarly, a small municipal utility in Ohio recently decided to build a 7MW storage facility connected to a 4.2MW solar plant, playing into the fast-acting grid frequency regulation market while also smoothing and shifting the output of the solar farm.

The utility-scale PV market is poised for exponential growth and yet the industry still has many fundamental opportunities to improve on standards and best practice. Tracker shade loss has been one of those topics that deserve more attention, but has been typically handled by derate factors rather than trying to accurately forecast the loss over the life of the system. Join Nextracker’s subject matter experts, Aron Dobos and Neelesh Umachandran, and Rounak Kharait, director of solar energy assessments at DNV, for a webinar about why shade modeling matters and recommendations on what the solar industry should do about it.

Join us to hear directly from the CTOs and heads-of-research from the top-20 cell/wafer producers to the PV industry today. The event will focus on predicting the key metrics underpinning the next big shift to n-type with answers to the key questions: When will the transition to n-type happen? Which companies will be first to 10 GW capacity and production? Who will be the key equipment suppliers for the new production lines? Which n-type process flow/architecture will emerge as the front-runner? What will polysilicon purity and wafer thickness levels look like for optimized n-type manufacturing? What will the upstream poly/wafer supply-chain look like in 5 years from now?
