Base Power
Base Power installs free home batteries in Texas and Illinois, profits from grid arbitrage.
Base has real utility deals and sticky customers, but it is burning cash far ahead of revenue while Tesla builds the exact grid coalition Base needs to win.
Base Power installs batteries in homes and makes money by buying and selling power to the electric grid during peak hours, without charging customers upfront (they pay monthly instead). It is hard to copy right now because Base has regulatory approvals, long-term contracts with customers, and owns its own battery factory, but Tesla already makes the same batteries, sells home power systems, and just teamed up with Sunrun and Renew Home to manage 16 gigawatts of home batteries for data centers, which is exactly what Base wants to do. The company raised $1.3 billion but only made $12 million in 2025, so the biggest question is whether the monthly payments and grid sales will eventually pay back the upfront costs or if Base will keep needing new money.
Base included in or excluded from a Tesla/Sunrun/Renew Home AI-data-center VPP aggregation deal within 6 to 12 months. Would show whether Base can compete for the growth pool it is targeting.
Gen 3 battery factory ships on schedule and 2026 revenue nears the ~$70M company projection. Would show whether Base's capital-intensive model is becoming self-funding or needs more raises.
- ~$1.3B raised total
- ~$12M 2025 revenue vs $70M 2026 target
- 20,000+ homes, 500+ MWh deployed
- 2026 revenue projection of ~$70M depends entirely on unproven Gen 3 factory scaling on schedule.
- New Illinois market launched July 2026 is untested outside Texas/ERCOT regulatory framework.
- Tesla-Sunrun-Renew Home 16 GW coalition could capture AI data-center VPP deals Base needs for growth.
- Valuation of ~$4B against ~$12M 2025 revenue implies a 100x-plus multiple unproven at scale.
- Unit economics of give-away financing model recovering value via grid arbitrage remain unvalidated long-term.

- Is Base Power profitable in 2026?
- No. Base Power's 2025 annualized revenue was estimated at around $12M against roughly $1.3B raised and a $4B valuation as of October 2025. The company projects about $70M in 2026 revenue, but that depends on its Gen 3 battery factory scaling on schedule, so profitability has not been demonstrated.
- Could AI replace Base Power's business?
- Not directly. Base Power's value comes from manufacturing and installing physical batteries, holding a Texas PUCT retail electricity license, and running 3 to 12 year customer contracts across 20,000-plus homes as of July 2026. AI could optimize dispatch software, but it cannot replace hardware, installation crews, or regulatory licensing.
- Who is Base Power's biggest competitor?
- Tesla, alongside Sunrun and Renew Home. In June 2026 the three formed a 16 GW virtual power plant coalition explicitly targeting AI data-center power demand, the same growth market Base Power is pursuing, and Tesla already owns Powerwall hardware plus its own Texas retail electricity license (Tesla Electric).
- How much has Base Power raised and who owns it?
- Base Power is privately owned and venture-backed, with no parent company. It has raised roughly $1.27 to $1.3 billion across four rounds through October 2025, including a $1B Series C led by Addition that valued the company at roughly $4B post-money, per TechCrunch reporting dated October 8, 2025.
- Does Base Power have layoffs or is it hiring?
- Base Power is hiring, not cutting. Crustdata tracked 402 employees as of July 20, 2026, up 125% year over year with 33 open roles, and the company said in July 2026 it plans to hire hundreds more staff to support its new Illinois expansion into ComEd territory.
- What is Base Power's business model?
- Base Power installs large ground-mounted home batteries, 25 to 80 kWh, for a low upfront fee of about $695 to $995, a monthly membership of about $19 to $29, and a 3-year electricity commitment near 8.5 cents per kWh, with battery agreements running up to 12 years, per TechCrunch reporting from October 8, 2025.
