Flexitricity
Flexitricity Limited is an Edinburgh-based energy flexibility aggregator and licensed electricity supplier operating what it describes as the first, largest and most advanced demand response portfolio in Great Britain — a virtual power plant exceeding 1GW. Founded in 2004 by Dr Alastair Martin, acquired by Alpiq in 2014, merged with Quinbrook's Velox Power in 2022, and per the company's own timeline acquired by Drax in 2026, it sits in the value chain between commercial, industrial and aggregated domestic energy assets and the GB wholesale and balancing markets. It routes customer assets — batteries, standby generation, industrial load, hydrogen electrolysers, co-located sites and, through its FlexGO product, residential EV charging — into the Balancing Mechanism, Capacity Market, frequency response, reserve services, the Demand Flexibility Service, DNO flexibility markets and wholesale trading. Its API posture is closed: Flexitricity publishes no developer portal, no documented public API, no OpenAPI, and no open market data of its own. The developer-facing subdomains developer., developers., docs., api. and data. do not resolve; the only interactive surface is portal.flexitricity.com, which requires a customer account. The United Kingdom has no consumer data-portability mandate comparable to Australia's Consumer Data Right, so nothing compels Flexitricity to expose customer usage data through an API. The open, machine-readable data about Flexitricity is published by Elexon, not by Flexitricity — its 63 registered BM Units under lead party FLEXTRCY are retrievable anonymously from the Elexon BMRS Insights API. Open on the regulator's side, closed on its own: that split is the finding.
Flexitricity is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Flexitricity is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
