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 profiled on the APIs.io network. Tagged areas include Energy, United Kingdom, Utilities, Electricity, and Demand Response.

Flexitricity’s developer surface includes developer portal, engineering blog, YouTube channel, and 17 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.

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/.
