Description: GWH ESS Tech October 20, 2025
ESS Tech, Inc. (NYSE:GWH) is a U.S.-based developer of iron-flow batteries that target commercial and utility-scale energy-storage projects. Its product suite spans the Energy Warehouse (behind-the-meter units for < 1 MW), Energy Center (modular systems that can be combined from sub-megawatt up to tens-of-megawatt), and Energy Base (a gigawatt-scale offering). The company was founded in 2011 and is headquartered in Wilsonville, Oregon.
From publicly available filings, ESS Tech reported roughly $30 million of revenue in FY 2023, with a cash-burn rate of about $12 million per quarter, indicating a runway of ≈ 6 months at current spending levels. The iron-flow technology it uses is positioned to benefit from the “long-duration storage” (LDS) trend, where analysts forecast a 30-35 % CAGR for LDS capacity through 2030, driven by higher renewable-penetration and the need for firm-capacity equivalents. In Q2 2024 the company announced a strategic partnership with a major European utility to pilot a 5-MW/20-MWh Energy Center, which could serve as a reference project for its pipeline of > 1 GW of contracted capacity.
Given the nascent stage of the iron-flow market and ESS Tech’s modest scale, the stock’s valuation is highly sensitive to execution risk and the pace of policy support for long-duration storage. Investors should monitor metrics such as installed megawatt-hours, order backlog growth, and the company’s ability to secure non-dilutive financing.
