Background

GridStor is a Portland, Oregon-based developer and operator of utility-scale, standalone battery energy storage systems (BESS) backed by Goldman Sachs Asset Management.

In 2022, following unsuccessful attempts to find the right capital deployment opportunities in the market, Goldman Sachs earmarked hundreds of millions in funding, originated the flagship Goleta Battery Storage project, and hired CEO Chris Taylor, a former Google energy executive. This served as the start of GridStor.

GridStor's leadership team has over 200 years of combined experience developing, building, and operating power generation and storage projects. The company focuses on high-growth markets experiencing rapid energy demand increases, particularly targeting regions like ERCOT in Texas and CAISO in California, as well as expanding into Arizona and Oklahoma.

GridStor currently manages a pipeline exceeding 5 GW of battery storage projects in later-stage development or under construction across the western and central U.S., positioning itself to serve utilities, data centers, and large industrial customers.

The company has established strategic partnerships with developers including Balanced Rock Power, Black Mountain Energy Storage, Strata Clean Energy, and Capacity Power Group, acquiring advanced-stage projects to rapidly deploy grid-stabilizing storage capacity in markets facing urgent reliability needs.
