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.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Flexitricity the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
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. From those artifacts we compute the Kin Score — Flexitricity scores 16.0/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Flexitricity
Each block below is one kind of artifact we hold for Flexitricity. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Flexitricity, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
