What SAE does

Ampeak Energy Limited (referenced in some firmographic sources as "SAE") is a UK-domiciled, AIM-listed developer, owner and operator of sustainable energy infrastructure, transitioning into a major Independent Power Producer (IPP). The company holds two categories of operating and development assets: grid-scale Battery Energy Storage Systems (BESS) — including the Uskmouth Sustainable Energy Park in Wales (circa 3.5GWh potential) and the Mey BESS project in Scotland (up to 1.2GWh) — and tidal stream generation anchored by the flagship MeyGen project in Scotland. MeyGen is described as the best tidal stream site in the world and, by end-2021, had produced 70% of cumulative global tidal energy output and continues to deliver over 90% of UK tidal output annually under an Ofgem/BEIS-tracked Contracts for Difference arrangement.

The business operates on an infrastructure IPP model with three revenue streams: (i) electricity generation sold into the UK National Grid under long-term power purchase / grid connection agreements, (ii) capacity payments from BESS assets providing grid stability and managing renewable intermittency, and (iii) government-backed CfD strike-price payments for the MeyGen tidal asset. Its go-to-market is enterprise-field-sales in nature, engaging directly with UK grid operators, energy offtakers, and regulatory bodies, with no consumer retail distribution; planning, CfD allocation rounds, and grid connection consents are the primary demand-capture mechanisms. Customer segments are concentrated around the UK National Grid and energy offtakers (primary) and corporate energy consumers seeking renewables for Net Zero compliance (secondary).

The company is small — approximately 40 employees across Edinburgh-headquartered corporate functions and operational sites in Newport (Wales) and Mey (Scotland) — and its strategy is explicitly aligned with the UK's binding Net Zero 2050 targets. Capital formation is conducted through public markets on AIM, supplemented by investor relations communications and shareholder engagement at annual general meetings; revenue figures, specific contract values, and pricing are not publicly disclosed.

Revenue model

1. Energy Generation and Sales: Revenue generated from selling electricity produced by tidal stream and battery storage projects to the national grid. The company operates as an Independent Power Producer (IPP) selling power to energy offtakers and grid operators.
2. Capacity Payments: Battery Energy Storage Systems provide grid stability services generating capacity payments for ensuring energy security and managing renewable energy intermittency.
3. MeyGen CfD (Contract for Difference): Government-backed contracts providing revenue certainty for renewable energy projects by guaranteeing a strike price for electricity generation.

Core offering

SAE is a developer, owner, and operator of large-scale sustainable energy projects in the UK, specializing in Battery Energy Storage Systems (BESS) and tidal stream generation. The company is transitioning into a major Independent Power Producer (IPP) with flagship assets including the Uskmouth Sustainable Energy Park (~3.5 GWh BESS) in Wales and the MeyGen tidal stream site (~1.2 GWh Mey BESS) in Scotland, producing electricity sold to the UK grid and supported by government-backed CfD contracts and grid capacity payments.

Product overview

Ampeak Energy operates as a developer, owner, and operator of sustainable energy projects, transitioning to become a major Independent Power Producer (IPP). The company's portfolio consists of two core asset categories: Battery Energy Storage Systems (BESS) and Tidal Stream generation. BESS operations include the Uskmouth Sustainable Energy Park in Wales (circa 3.5GWh capacity) and the Mey BESS project in Scotland (up to 1.2 GWh). Tidal stream generation is anchored by the MeyGen project in Scotland, which is the world's leading tidal energy site.

Products and services

• Uskmouth Sustainable Energy Park A sustainable energy park in Wales being transformed into one of the largest Battery Energy Storage Systems sites in the UK, capable of supporting circa 3.5 GWh of battery storage to support the energy transition to Net Zero, ensure energy security, and manage renewable integration for grid operators and energy offtakers.
• Mey BESS A battery storage project in Scotland delivering up to 1.2 GWh of storage capacity at a critical renewable energy site, supporting nearby onshore and offshore wind and tidal stream projects with grid stabilization and renewable integration services.
• MeyGen Tidal Stream Project Flagship tidal stream generation project in Scotland that harnesses tidal power to generate clean, renewable energy supplied to the grid under a CfD contract; produces over 90% of the UK's total tidal output annually and 70% of global tidal energy (Ofgem public records, BEIS).

Quantifiable outcome

• By end of 2021, MeyGen had produced 70% of global tidal energy output

Direct peers

• Statera Energy: UK-based utility-scale battery storage developer and operator with a multi-GWh BESS pipeline. Statera is one of the closest comparables to Ampeak's planned Uskmouth and Mey BESS projects in terms of geography, business model, and stage of development.
• Gore Street Energy Storage Fund: London-listed investment company focused on UK and international battery storage assets. Gore Street operates a portfolio of operational and development-stage BESS, directly comparable to Ampeak's planned BESS IPP business model.
• Harmony Energy Income Trust: London-listed fund dedicated to UK battery storage projects, owning and operating BESS assets under construction or in development. Highly comparable to Ampeak in target geography, technology focus, and revenue model (capacity market and balancing services).
• Penso Power: UK-based developer of grid-scale battery storage projects with a multi-GWh pipeline. Penso's developer model and UK BESS focus make it a close comparable to Ampeak, particularly around project development, grid connection strategy, and revenue stacking.
• Gresham House Energy Storage Fund: London-listed fund investing in UK battery energy storage systems with operational and development-stage assets. Closely comparable to Ampeak on geography, technology, and the IPP/operator business model for BESS.

Broad incumbents

• Drax Group: UK-listed Independent Power Producer and largest renewable power generator in the UK. Drax operates biomass generation and is expanding into battery storage, making it a direct comparable for Ampeak's BESS IPP strategy, though at substantially larger scale and broader portfolio.
• SSE plc: UK-listed integrated utility with significant renewable generation and growing battery storage portfolio. SSE competes with Ampeak in the same UK BESS development pipeline and CfD allocation rounds, with substantially greater resources.
• EDF Energy: UK subsidiary of EDF with significant renewable generation portfolio and growing battery storage interests. EDF competes directly with Ampeak for UK CfD allocations and capacity market participation, with substantially greater scale.
• Centrica plc: UK-listed energy company with growing investments in renewable generation, battery storage, and flexibility assets. Centrica's strategic pivot toward distributed energy and grid services places it in direct competition with Ampeak's IPP model.

Emerging players

• Atlantis Resources: Marine/tidal energy developer with historical involvement in the MeyGen tidal stream project (predecessor/related entity to Ampeak's tidal asset). Relevant as a tidal stream sector comparable, though the company has undergone significant restructuring.
