Centerpoint Energy Plans Pricing
CenterPoint Energy exposes three integration surfaces. The Smart Meter Texas (SMT) Usage History Inquiry API is operated by the Smart Meter Texas consortium for Texas TDSPs (CenterPoint participates as a member) — access requires SMT Third-Party Service Provider registration and is free to authorized TPSPs. Green Button Connect My Data follows the NAESB ESPI standard and is free to authorized third parties acting on customer consent. The Centerpoint Connect Services API at api-portal.centerpointconnect.io is a partner / contractor portal that gates products behind login; per-product pricing is not published publicly.
