What YLEM Energy does
YLEM Energy Limited is a UK-based, privately held onsite energy generation and management specialist founded in 1991 and headquartered in Salford (Greater Manchester). The company designs, funds, builds, owns, operates and maintains behind-the-meter energy assets for large energy-intensive businesses spending over £500,000 annually on energy, serving primary verticals including manufacturing and automotive alongside pharmaceuticals, food & beverage, and chemicals. Its core offering combines hydrogen-ready gas power generation, commercial solar PV, battery energy storage, and the YLEM Energy Optimise smart energy management portal, with sub-metering, a Building Energy Management System (BEMS), and the YLEM Energy Xchange peer-to-peer energy trading platform deployed as modular add-ons.
Revenue is generated primarily through long-term Power Purchase Agreements (15-25 years) under which customers purchase electricity from YLEM-owned generation assets at fixed rates typically below National Grid pricing, supplemented by subscription-based BEMS services and recurring 24/7 Operations & Maintenance contracts. The company is wholly owned by Ylem Group Limited alongside subsidiaries Root-Power Limited and Power-Zero Limited (the rebranded Solar PPA and Optimise commercial brand). Distribution is direct enterprise sales to large UK accounts, with a regionally distributed engineering team supporting the installed base. The company holds ISO 9001, ISO 14001 and ISO 45001 certifications.
Cumulative reported metrics include 600+ projects funded since 1991, £300m of self-funded project value, 600+ MW of gas power generation delivered or worked on, 18.6m+ live generation hours, and over 1.1 million tonnes of CO2 saved for customers, with average customer annual savings of £227k and BEMS-led cost reductions of 40% on gas and 20% on electricity. Named enterprise customers include Unilever, JCB, Vauxhall, Denby Pottery, IAC Automotive, Scapa UK and Marlin Industries, with O&M services provided to assets such as Triple Point's 42.5MW of peaking plant.
