About Flexitricity

Flexitricity is Britain’s leading demand-side response (DSR) business, providing short-notice response and reserve energy which is cheaper and greener than conventional power stations. Flexitricity plays a key role in the renewable energy revolution and in the electrification of heat and transport as we strive toward net zero.

Flexitricity pioneered aggregated DSR for electricity system balancing, and continues to lead this sector in volume, technical capability, and innovation. Flexitricity aggregates small generators, energy storage sites and flexible industrial and commercial energy users, making their capacity available to National Grid and Distribution Network Operators (DNOs) for periods of stress in electricity systems. Participating assets are owned by third-party companies who partner with Flexitricity to profit from their flexibility.

To complement the core DSR offer, in October 2018 Flexitricity launched a unique energy supply offering, Flexitricity+. Flexitricity+ provides transparent market access for combined heat and power operators, battery developers, merchant generators and energy-intensive industrial sites. Using our 24-hour control room and live smart grid platform, we monetise the flexibility of our customers in the energy markets and the Balancing Mechanism. In 2020, this market access widened as we took flexibility into the Balancing Mechanism as a Virtual Lead Party for the first time.

Flexitricity is a wholly-owned subsidiary of Quinbrook Infrastructure Partners. We are passionate and committed to sustainable and responsible business practice across all aspects of environment, social and governance, including delivering equal opportunities and an inclusive workplace.

About the role

The Capacity Market Manager role will be responsible for Flexitricity’s existing and future contracts in the GB Capacity Market. 

The Capacity Market (CM) is one of the key policies of the Electricity Market Reform programme. The CM aims to ensure the future security of our electricity supply at the lowest cost to consumers.

Flexitricity was a first mover in the Capacity Market, having secured contracts for our Energy Partners in all auctions since 2014. Due to significant company growth, Flexitricity has an opportunity for a dedicated full-time role within the Supply and Balancing Services team to manage the end-to-end Capacity Market process.

    • Manage the pre-qualification of assets in collaboration with business development and account management teams, including data gathering, exhibit creation and application submission.

    • Submit auction bids to win desired contracts and report on results.
    • Deliver post-auction activities to meet all pre-contract milestones – Financial and Substantial Completion Milestones, six-monthly progress reports, meter assessments and tests and DSR tests.
    • Deliver ongoing contract management with the Operations team through timely submission of Satisfactory Performance Days.
    • Stay up-to-date on changes to Capacity Market rules.
    • Evaluate opportunities to add value through secondary trading.
    • Stakeholder engagement with third parties, including the EMR Delivery and Settlement bodies, Low Carbon Contracts Company (LCCC) and the Electricity Settlement Company (ESC).
    • Internal reporting on contract performance, rule changes or regulatory updates.
    • Extensive understanding of the Capacity Market Rules and Regulations and ability to articulate potential legal challenges to external stakeholders if the interpretation of certain rules impact Flexitricity’s performance.
    • Lead on responses to consultations initiated by Ofgem and BEIS.
    • Identification of areas of risk and/or improvement and develop methods of streamlining existing processes.
    • Acting as an ambassador and role model for the Flexitricity brand.

The Capacity Market Manager sits within Supply & Balancing Services, part of the Finance Team, and will report to the Head of Supply & Balancing Services.
