Drax Signs Tolling Agreement for West Burton C UK BESS Project

Author:

What the Tolling Agreement Is

  • Drax Group plc has signed a 10-year tolling agreement with West Burton C Limited, a company owned by battery storage developer Fidra Energy, for a 250 MW / 500 MWh battery energy storage system (BESS) located at the West Burton site in England.(Drax Global)
  • The agreement gives Drax full operational control and dispatch rights for the BESS.(Solar Power Portal)
  • The arrangement is capital-light for Drax — no upfront capital cost — because Fidra retains responsibility for construction, maintenance, and availability risk.(Drax Global)

Project Details

  • Capacity: 250 MW with 500 MWh of storage, meaning the system can discharge its full capacity for about two hours — a typical duration for grid balancing and peak support.(Drax Global)
  • Commercial Operation Target: The project is expected to reach commercial operation around 2028–2029, contingent on Fidra taking a final investment decision by Q3 2026.(Solar Power Portal)
  • Revenue Retention: Under the tolling structure, Drax retains most revenues from asset dispatch, except for Capacity Market revenues, which are excluded.(Solar Power Portal)
  • Payments: Drax will pay a fixed annual tolling fee indexed to the UK Consumer Prices Index (CPI) over the 10-year contract.(Solar Power Portal)

Strategic and Business Context

  • This is Drax’s first tolling agreement for a BESS project, marking a notable step in its strategy to build a gigawatt-scale battery storage pipeline as part of its FlexGen business, which focuses on flexible and fast-response generation and storage.(Reuters)
  • The deal complements Drax’s recent investments including:
  • The tolling agreement allows Drax to expand its operational footprint in battery storage without large capital deployment upfront, while positioning itself as a major player in UK grid flexibility and decarbonisation solutions.(Drax Global)

Key Executive Commentary

Will Gardiner, CEO of Drax, highlighted why the agreement is significant for the company’s strategy:

“Flexible Generation technologies like battery storage will support a secure, affordable and clean energy system for British homes and businesses. Our first BESS tolling agreement is an important step in our ambition for a gigawatt scale pipeline of battery storage opportunities…”(energyglobal.com)

This comment points both to long-term growth ambitions and alignment with UK national energy goals, including grid reliability and decarbonised power.(energyglobal.com)

Why It Matters

Here’s what industry observers see as the significance of this development:

Grid Stability & Energy Transition
Battery storage systems help balance supply and demand, support intermittent renewable generation (like wind and solar), and improve system resilience — all key priorities for the UK power grid.(energyglobal.com)

Capital-Efficient Expansion
By using a tolling agreement, Drax expands battery storage capacity without bearing construction and maintenance risk — a model increasingly used in the BESS sector.(Energy Storage)

Strategic Fit with Market Trends
The agreement reflects broader growth in UK BESS activity, where developers and utilities seek flexible capacity to support decarbonisation and technical grid needs.(Energy Storage)

What Comes Next

  • Final Investment Decision (FID): Expected by Q3 2026.(Drax Global)
  • Commercial Operations: Targeted for 2028–2029.(Solar Power Portal)
  • Further Growth: Drax aims to scale battery storage as part of a gigawatt-scale FlexGen platform combining owned assets, optimisation capabilities, and tolling/floor arrangements.(DirectorsTalk Interviews)

Here’s a case-study summary with structured analysis and comments on Drax’s tolling agreement for the West Burton C UK BESS project — looking at what the deal is, strategic context, comparisons with other battery storage transactions, and expert/industry commentary.

Case Study: Drax Tolling Agreement with West Burton C Ltd (Fidra Energy)

What the Agreement Is

  • Drax Group plc signed a 10-year tolling agreement with West Burton C Limited, owned by UK BESS developer Fidra Energy, for a 250 MW / 500 MWh battery energy storage system (BESS) at the West Burton site in Nottinghamshire, England. (Drax Global)
  • Tolling structure:
    • No upfront capital cost for Drax — Fidra takes on construction, maintenance, and availability risk. (Drax Global)
    • Drax gains full operational control and dispatch rights once in service. (Drax Global)
    • Drax will pay a fixed annual tolling fee, indexed to UK inflation (CPI), over 10 years. (Drax Global)
    • Drax retains most trading and dispatch revenues, excluding capacity market revenues. (Energy Storage)
  • Expected commercial operation: Around 2028–2029, subject to a final investment decision by Q3 2026. (Energy Storage)

Strategic Rationale — Why It’s Important

Drax’s FlexGen Strategy

This tolling deal is a strategic milestone in Drax’s push to build a gigawatt-scale battery storage portfolio under its FlexGen business model — which blends owned battery assets with optimisation and third-party control agreements. (Drax Global)

  • It complements recent strategic moves such as:
    • The acquisition of Flexitricity, a UK energy optimisation and asset management platform. (DirectorsTalk Interviews)
    • The purchase of three BESS development projects from Apatura, totalling 260 MW. (Chamber Members)

This combination (owned assets + optimisation tech + tolling contracts) is meant to allow Drax to capture more value from operational flexibility and energy trading. (DirectorsTalk Interviews)

How Tolling Agreements Work — In Context

A tolling agreement lets a company like Drax operate and monetise a power or storage asset without owning it — instead paying a fee to the developer and taking on revenues and dispatch decisions.

This model is gaining traction in UK BESS markets because it allows:

  • Developers (like Fidra) to reduce exposure to wholesale merchant risk.
  • Operators (like Drax) to scale capacity capital-light and capture fast-response revenues from grid balancing and energy arbitrage. (Energy Storage)

In other sectors, similar structures have become common as the pace of grid storage deployment accelerates — though exact risks and rewards vary by contract terms and market conditions.

Industry Commentary & Expert Views

From Drax Leadership

Will Gardiner, CEO of Drax, described the agreement as:

an important step in our ambition for a gigawatt-scale pipeline of battery storage opportunities, aligned with the UK’s energy security and decarbonisation goals. (Drax Global)

Comments like this highlight how Drax sees BESS not just as stand-alone assets but as part of a larger energy transition strategy mixing flexibility and grid support.

Market Commentary

  • Analysts note that capital-light tolling deals are an attractive way for large utility players to expand storage portfolios when capital discipline and risk management are priorities. (TipRanks)
  • Industry news sources call this move “aligned with UK energy objectives,” emphasizing energy security, flexibility, and decarbonisation priorities. (MarketScreener)

Comparisons & Broader Sector Trends

To understand the deal’s context within broader BESS markets:

UK BESS Market Growth:
Capacity auctions (e.g., UK T-4 for 2028/29) have procured gigawatts of new energy storage, showing strong market demand for flexibility as renewables rise. (Energy Storage)

Other Tolling Deals Emerge:
Tolling structures weren’t common in early UK BESS pipelines but have grown since mid-2024 when developers and operators began using them to hedge merchant risk. (Energy Storage)

Comparable Partnerships:
Other players (like Octopus Energy or specialist funds) have also tested third-party BESS operations to capture value without carrying full development risk — a trend seen in recent UK storage deals. (Energy Storage)

Key Takeaways & Comments

 Strategic insights

  • Capital-light expansion: Drax adds meaningful BESS capacity without large upfront build costs. (Reuters)
  • Flexible generation integration: The project builds on Drax’s FlexGen platform, pairing storage with optimisation tech and physical assets. (DirectorsTalk Interviews)
  • Exposure to grid services: Drax gains exposure to balancing, ancillary services, and dispatch markets — increasingly valuable as renewables grow. (Drax Global)

 Risk considerations

  • Tolling deals mean developers retain construction risk — but Drax carries merchant exposure and must manage volatility. (Energy Storage)
  • The project’s value depends partly on future UK energy market dynamics and policy environments.
