What Alcemi does
Alcemi is a London-based private developer of grid-scale battery energy storage systems (BESS) focused on the UK electricity transmission network. Its portfolio is anchored by transmission-connected lithium-ion BESS projects co-developed with Copenhagen Infrastructure Partners (CIP), including the 500MW Devilla project in Kincardine, Scotland — described as among Europe's largest operational BESS assets on commissioning, targeted for 2028 — within a three-project co-development portfolio totalling 1.5GW. The company is also advancing a broader 4.5GW pipeline of BESS projects across Scotland and England.
Alcemi monetises assets through long-duration, contract-based revenue mechanisms rather than software-style fees: 15-year capacity market agreements under the UK regulatory framework provide predictable, regulatorily underpinned revenue streams, while a 10-year optimisation agreement with SSE plc covers technical performance and revenue optimisation of the Devilla asset. Strategic capital is provided by CIP (majority owner across co-developed projects), with the Scottish National Investment Bank and the Nuclear Liabilities Fund holding minority long-term stakes in Devilla.
Operationally, Alcemi runs a lean team of 1–10 employees and functions as a development-led entity, with CIP leading construction and majority ownership on co-developed projects. The customer base is structurally concentrated on UK transmission system operators and a single Tier-1 optimisation counterparty (SSE plc), and the company is pre-revenue at the portfolio level, with first material cashflows contingent on commercial operation dates from 2028 onward.

Alcemi competitors and assessment
Company assessmentDirect peers
- TagEnergy: European battery storage developer with active UK project pipeline. Comparable to Alcemi in developing grid-scale BESS, leveraging institutional capital partners, and targeting transmission-connected storage assets across the UK and Europe.
- Harmony Energy: UK-based developer of utility-scale battery energy storage projects with a multi-GW pipeline. Directly comparable to Alcemi in target market (UK grid services), technology (lithium-ion BESS), and business model (grid-connected storage development with long-term revenue contracts).
- InterGen: Global power generation developer with operational BESS projects in the UK. Comparable to Alcemi in developing transmission-connected battery storage in the UK, with infrastructure-grade partners and long-term capacity-type revenue arrangements.
- Low Carbon: UK renewable energy developer with a dedicated battery storage portfolio including large-scale BESS projects. Comparable to Alcemi in developing UK-based grid-scale energy storage, securing long-term revenue agreements, and operating alongside renewable generation assets.
- Zenobē Energy: UK-headquartered BESS developer and operator with a significant UK and European pipeline. Comparable to Alcemi in developing transmission- and distribution-connected battery storage, securing long-term offtake and capacity contracts, and partnering with infrastructure capital.
- Pivot Power (EDF Renewables UK): UK developer of transmission-connected battery storage hubs, now part of EDF Renewables UK. Comparable to Alcemi in developing utility-scale, transmission-connected BESS for grid balancing and capacity services in the GB market.
- Penso Power: UK-based developer focused on grid-scale battery storage projects supplying flexibility services to the GB market. Directly comparable to Alcemi in technology focus (large-scale lithium-ion BESS), target customers (UK grid operators), and revenue model (ancillary and balancing services).
Broad incumbents
- Drax Group: UK-listed power generation group with renewable generation assets and an emerging BESS portfolio. Comparable to Alcemi in targeting UK grid services and balancing markets with battery storage, but operating as a large incumbent across generation, supply, and optimization.
- Fluence Energy: Global leader in grid-scale battery energy storage products, services, and digital applications for renewables and storage. Comparable to Alcemi in the underlying BESS technology stack and UK market presence, though Fluence spans hardware, software, and services across many geographies.
- Statkraft: Europe's largest generator of renewable energy with an active UK and European BESS development pipeline. Comparable to Alcemi as a broader incumbent pursuing utility-scale battery storage in the UK, but operating at much larger scale across multiple technologies and geographies.
