Mems Power Generation

What Mems Power Generation does

MEMS Power Generation Limited is a UK-based private temporary power solutions provider headquartered in Gillingham, England, operating a fleet of over 500 diesel and HVO-compatible generators ranging from 30 kVA to 2000 kVA, with multi-set paralleling capability up to 25 MW. The company serves enterprise, utility, healthcare, data centre, government, education, sport, and live event customers across the United Kingdom with two core offerings: emergency generator hire (24/7/365 response, documented 3-hour deployment) and planned outage support. Technology differentiators include Stage V compliant emissions systems, a proprietary MEMS Connect telemetry platform for remote monitoring and predictive refuelling, Multi-GenPower twin-engine load-on-demand systems, and hybrid Battery Energy Storage System (BESS) integration that achieves up to 43% fuel and emissions reduction versus conventional generator-only deployments. Supporting services span logistics, installation, fuel management, 24-hour control room oversight, and disaster recovery planning.

The business operates a sales-led, quote-based revenue model combining usage-based generator rental with professional managed services. Revenue streams are predominantly project-based and tied to emergency events or scheduled outages rather than disclosed recurring contracts. Customers range from small businesses to blue-chip multinationals and utility operators, with referenceable deployments including the Tower of London, a Premier League stadium, a major UK university, a London data centre, and an 819 MW UK gas-fired power station. Go-to-market is direct via phone (08452 230 400), website quote forms, and content marketing through case studies; there is no disclosed channel partner, reseller, or geographic expansion beyond the United Kingdom.

Founded in 1984 with 51-100 employees, MEMS is privately held with no disclosed external investors, funding rounds, or M&A activity. The company is positioning around UK decarbonisation through HVO compatibility, Stage V emissions compliance, and hybrid BESS offerings, aligning its traditional asset rental business with sustainability-driven procurement criteria across data centre, healthcare, and utility buyers.
