Seven Regional Clean Energy Companies Graduate from Cleantech San Diego Startup Accelerator
SAN DIEGO, CA, March 6, 2025 – Cleantech San Diego today announced the graduation of seven local clean energy companies – ChargeNet Stations, Helicoid, Paired Power, Redoxblox, Sonocharge, Uprise Energy, and Xtelligent – from its Southern California Energy Innovation Network (SCEIN).
SCEIN is an accelerator program for clean energy startups based in San Diego, Riverside, San Bernardino, and Imperial counties that are developing technologies to help California meet its clean energy goals. The program offers free business services through a consortium of regional partner organizations and private sector companies to help entrepreneurs successfully bring their energy innovations to market.
Since entering SCEIN, these seven companies have secured multiple customers, built robust sales pipelines, and raised sufficient capital to support the scaling of their breakthrough energy businesses. A company graduates from SCEIN when it is mutually agreed that they have utilized the full range of resources and referrals made available to them. Seventeen regional clean energy companies have now graduated the program after receiving customized business service plans from SCEIN.
“SCEIN is pleased to have been able to provide services and support that has enabled all seven of these innovative companies to accelerate market traction of their breakthrough clean energy solutions,” said Zac Dobbin, Director of SCEIN. “Each of their products create exciting new ways for customers to reduce energy use, save money, and curb greenhouse gas emissions – all while creating new jobs and furthering California’s cleantech economy and energy goals.”
Cleantech San Diego launched the SCEIN program in 2016 after winning a grant from the California Energy Commission. Over the program’s nine years of operation, SCEIN member companies have commercialized innovative technologies that are accelerating market transformation in transportation electrification, grid and building decarbonization, energy efficiency, and resiliency.
To date, 78 companies have been served by SCEIN, 38 of which are currently active in the program. Together, these startups employ 851 people, have had 527 patents approved, and have raised over $672 million in follow-on funding from public and private sources since being accepted into the program. 82 percent of SCEIN companies have C-Suite diversity.
“Now in its ninth year, the Southern California Energy Innovation Network program is a proven model for success, and we are tremendously grateful to the California Energy Commission for the vision they had for our program to help the next wave of energy entrepreneurs bring their technologies to market, while ensuring the state of California remains competitive in the clean energy sector,” said Cleantech San Diego President and CEO Jason Anderson. “It is inspiring to see SCEIN companies commercializing cost-effective cleantech solutions that can help all Californians reduce their energy costs and environmental impact.”
SCEIN applications are accepted on a rolling basis. Anyone interested in applying as an entrepreneur or hosting a pilot demonstration project for a cleantech startup can learn more at cleantechsandiego.org/scein.
