ISO connects largest battery system in the US to the grid
The California Independent System Operator (ISO) connected the largest battery storage resource in the nation to its power grid in June, signaling an era of rapid battery growth on the electricity grid in the next several years.
The initial phase of LS Power Group’s Gateway Energy Storage Project in San Diego County came online June 9, adding 62.5 megawatts (MW) of storage interconnection to the ISO grid. The power grid currently has just over 216 MW of storage capacity in commercial operation. If all planned projects in the interconnection queue are completed on schedule, storage capacity will jump to 923 MW by the end of 2020, a six-fold rise from 136 MW at the beginning of the year.
Batteries are widely seen as an important strategy for incorporating and managing rising amounts of renewables onto electricity grids.
The Gateway project, a lithium-ion battery system, will have a total capacity of 250 MW when it is in full operation in August, making it reportedly the largest operating Battery Energy Storage System (BESS) in the world.

New tool enhances initiative comment process
As part of our commitment to improve customer service and stakeholder processes, the ISO is launching its online commenting tool in August to standardize the submission and management of stakeholder comments.
Stakeholder input is vital to the success of the ISO’s development and implementation of new market designs, policies and infrastructure planning. The stakeholder initiative process allows all stakeholders to provide valuable feedback that helps shape the future of the ISO’s energy markets and operations.
To enhance and streamline the initiative development process, the ISO created a commenting tool with functions that make it easier for stakeholders to view comments with a single click, filter and organize comments, along with having the ability to download selected comments in a spreadsheet format. The online comments template will allow stakeholders to incorporate graphics, tables and footnotes within their comments. The new tool also strengthens cyber security for the ISO and stakeholders.
The ISO’s ongoing stakeholder initiatives are available on the ISO's Stakeholder Initiatives webpage.

The ISO extends in-person meeting restrictions
In response to the ongoing COVID-19 pandemic, the ISO is extending restrictions for all in-person meetings at its offices and off-site venues until further notice.
The ISO had previously set September 14 for reopening its offices and resuming in-person meetings. With the recent reports of increased virus cases in California and elsewhere, the ISO is extending the restrictions and will not be scheduling any in-person meetings or tours in the near future, to protect the health of staff, stakeholders, and the community.
Meetings continue to occur via teleconferences or webinars, with the same notifications to stakeholders through notices and the website. The ISO continues to closely monitor outbreak developments, and follow state and county guidelines for public health protocols.
While the pandemic and statewide restrictions have not caused reliability issues with the electricity system, the power grid has experienced a moderate amount of reduced energy usage due to the pandemic and state limitations on businesses. An updated analysis of load impacts is publicly available on the News webpage of the ISO’s website. A COVID-19 section on that page houses all pandemic-related news and presentations.
The ISO will provide periodic updates to help stakeholders actively participate in meetings. Visit caiso.com for the latest information regarding meetings and visitor restrictions, follow us on Twitter at @California_ISO. To track notices and activities, follow @ISOMarketNotice, and sign up for the Daily Briefing.
