Base Power

Base Power (Base Texas REP, LLC, PUCT License #10338) is an Austin, Texas home energy company that pairs an installed home battery (40–80 kWh) with retail electricity service across Texas and Illinois. The battery powers a home automatically during outages with no manual switch and helps lower the energy bill: batteries charge when grid demand is low and send power back to the grid when demand is high (grid-balancing), and that grid revenue helps keep member energy rates low. Base can be the retail electricity provider with or without a battery, works with existing solar, and serves the Oncor, CenterPoint, AEP Texas, TNMP, CoServ, GVEC, Farmers Electric, and El Paso Electric areas in Texas plus ComEd in Illinois. Led by CEO Zach Dell and co-founder Justin Lopas; named to the TIME100 Most Influential Companies (2026); backed by Andreessen Horowitz, Lightspeed Venture Partners, Addition, Bond Capital, Ribbit Capital, and Spark Capital. This profile was enriched by the API Evangelist pipeline; Base publishes no public developer API.

Base Power is profiled on the APIs.io network. Tagged areas include Company, Clean Energy, Energy, Home Battery, and Energy Storage.

Base Power’s developer surface includes engineering blog, support, pricing, signup flow, and 7 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/base-power: open an issue to ask a question, or submit a pull request to add artifacts.
