Energy-io

What Energy-io does

Energy-io is a UK-based private electrical engineering services firm specialising in the integrated delivery of Electrical Balance of Plant (EBOP) for grid-scale renewable energy infrastructure. The company serves renewable energy developers, asset owners, and energy network operators, delivering services that span electrical design, grid compliance strategy, high-voltage construction leadership, and protection/control commissioning — packaged as a single structured function rather than disconnected workstreams. Its core project portfolio covers Battery Energy Storage Systems (BESS), large-scale onshore wind farms, and transmission substations operating at voltages from 33kV distribution networks to 400kV supergrid connections. Named engagements include Hams Hall BESS (350MW/1.2GWh) and Berkswell BESS (200MW/857MWh) for BW ESS, wind farm delivery for ScottishPower Renewables, BESS delivery for Eelpower, and commissioning support for SP Energy Networks.

The company operates an enterprise field-sales GTM targeting senior technical and commercial stakeholders at major UK energy companies, with project-based professional services revenue generated through fixed-price contracts and managed service engagements. The firm's competitive positioning is anchored on a transmission-led technical depth — leadership includes a Technical Director with 25+ years in transmission-level networks, a Project Director with 10+ years across UK/global EPCs, and an Operations Director with 20+ years in HV operations — combined with an integrated delivery model that reduces interface risk and accelerates energisation certainty. Energy-io maintains a five-partner construction and technology ecosystem (Livingston ME, Glenturas Construction, Nexus Power, Direct Strike, Laplace Solutions) to scale execution beyond in-house capacity while remaining the single accountable client interface.

The company is headquartered in Glasgow with a Birmingham regional operations hub, is privately held with no disclosed external funding or parent entity, and operates exclusively within the UK market. It is led by founder-engineers and has no AI/ML, software platform, or recurring SaaS revenue layer — value creation is fundamentally tied to senior human engineering judgement, domain expertise in transmission-connected infrastructure, and execution credibility with tier-1 renewable energy developers.

Core offering

Energy-io provides integrated electrical design, grid compliance strategy, and construction leadership for grid-scale renewable energy projects as a single unified function. The firm delivers electrical balance of plant (EBoP) services for battery energy storage systems (BESS), large-scale onshore wind farms, and high voltage transmission substations ranging from 33kV distribution networks to 400kV supergrid connections. Engagements span the full project lifecycle from early design and grid code compliance through HV construction, protection and control commissioning, and ongoing operational support.

Product overview

Energy-io offers an integrated service delivery model for grid-scale renewable energy projects, combining three core product offerings (Battery Energy Storage Systems, Large Scale Onshore Wind Projects, and Transmission Substations) with six service modules (Electrical Balance of Plant, Grid Interface & Compliance Strategy, High Voltage Construction & Installation, Protection/Control & Commissioning, Integrated Electrical Project Leadership, and Operational & Lifecycle Support). The integrated structure unifies electrical design, grid compliance strategy, and construction leadership within a single delivery model, reducing interface risk and accelerating decision-making from early design through to energisation and ongoing operations.
