# Base Power's Second $1B Round: Home Batteries as Grid Infrastructure at $13B

> Ribbit, Addition, Valor Equity, and JPMorgan's Strategic Investment Group led Base Power's $1B Series D at $13B post-money — funding U.S.-made Base Core batteries and a virtual power plant at residential scale.

**Base Power** closed another **$1 billion** round — Series D at **$13 billion** post-money — on August 3, 2026, less than a year after a **$1B Series C**. Total capital raised sits **above $2.5B**. The company is betting that **backyard batteries are grid infrastructure**, not solar accessories.

### Deal snapshot
- **$1B Series D** @ **$13B** post-money
- **Leads:** [Ribbit Capital](/fund/ribbit-capital), [Addition](/fund/addition), Valor Equity Partners, JPMorganChase Strategic Investment Group
- **Directory participants:** [Altimeter](/fund/altimeter-capital), [D1 Capital](/fund/d1-capital), [Coatue](/fund/coatue), [Energy Impact Partners](/fund/energy-impact-partners), [Thrive Capital](/fund/thrive-capital), [a16z](/fund/andreessen-horowitz), [Lightspeed](/fund/lightspeed-venture-partners-nyc)
- **HQ / mfg:** Austin, Texas (Base Factory 1)
- **Profile:** [Base Power](/startup/base-power)

### Who uses the product — and why
**Homeowners** buy large residential batteries (Base Core in the ~39–40 kWh class per press) for outage backup and, where Base sells retail power, a simpler energy bill. **Utilities** (Austin Energy, El Paso Electric and peers cited in prior coverage) can tap the fleet as distributed flexibility.

Press reports **500+ MWh** installed and on the order of **~100 installs/day**, with ambitions to double by year-end. Two go-to-market modes appear: sell kWh in retail-choice markets; sell battery control / capacity to utilities in regulated markets.

**Job for the household:** keep the lights on and lock in economics. **Job for the grid:** get fast-deployed storage without waiting for a single 200 MW substation project.

### Why this is a live problem now
- Extreme weather + AI data-center load stress distribution grids.
- Lithium home storage works for hours; Base’s thesis is **fleet scale + software + vertical install** as a VPP.
- U.S. manufacturing and Security & Resiliency capital (JPMorgan SIG) match a policy-friendly narrative.
- Second $1B round in ~10 months signals growth investors treating this like a category-defining infra company, not a regional solar dealer.

### Why these funds fit
| Investor | Fit |
| --- | --- |
| **[Ribbit](/fund/ribbit-capital)** | Consumer + financial rails thinking applied to energy-as-a-service. |
| **[Addition](/fund/addition)** | Already led/anchored prior mega-round; compounding ownership in a breakout climate infra story. |
| **[a16z](/fund/andreessen-horowitz) / [Thrive](/fund/thrive-capital) / [Lightspeed](/fund/lightspeed-venture-partners-nyc)** | Existing syndicate doubling down on American industrial + climate scale. |
| **[Altimeter](/fund/altimeter-capital) / [Coatue](/fund/coatue) / [D1](/fund/d1-capital)** | Crossover/growth capital for a pre-IPO trajectory company. |
| **JPMorgan SIG** | Balance-sheet + resiliency mandate — unusual and telling for a “startup” battery maker. |

### Competitive map
- **Tesla Powerwall / Sunrun / Generac** — residential storage and backup incumbents.
- **Utility-owned storage and stand-alone BESS developers** — different form factor, same grid job.
- **Pure software VPPs** without owned hardware — lighter capital, less install control.

### Practical takeaways
1. **Founders:** Vertical integration (factory + crews + retail license) is the moat story — and the burn story. Model both.
2. **Investors:** Compare **$/MWh deployed** and attach rates, not only valuation vs Tesla Energy narratives.
3. **Operators / utilities:** Ask who controls dispatch and how residential churn affects capacity commitments.

### When not to
- Do not treat $13B as a public-market comps shortcut — still private, manufacturing and geographic expansion risk ahead.
- California and other large markets may not be online yet; Texas/Illinois density is not national coverage.
- Michael Dell did **not** participate per TechCrunch — ignore that rumor in diligence notes.
