Balancing the grid for a renewables-led future

Our technologies stabilise the grid by supplying power when renewables fall short and storing excess energy when production exceeds demand.

The challenge we’re solving

Wind and solar power are a crucial part of the UK’s clean energy transition – but they don’t deliver power all the time. The grid needs flexible and reliable assets like Statera’s, to keep the lights on when there is a shortfall or excess of wind and solar power.

Our technologies step in when renewable generation can't meet demand, and store surplus energy when production exceeds it – ensuring a stable, secure power supply.

Our Technologies

Through a combination of flexible generation and both short- and long-duration storage, we help balance the grid and enhance the UK’s energy security.

Technology

Battery storage

Battery Energy Storage Systems (BESS) soak up surplus energy from the grid when supply exceeds demand and release it when demand is high or renewables aren’t producing enough power.

Technology

Pumped storage hydro

Pumped hydro-electric storage is a proven zero carbon technology for medium-duration energy storage. Although its expansion is limited by geography, it represents a significant source of the UK’s storage capacity.

Technology

Hydrogen

Green hydrogen is produced via electrolysis powered by renewable energy. The hydrogen can then be stored before being used to run low-carbon flexible thermal generation plants, which is crucial for balancing the grid and reaching net zero.

Technology

Flexible generation

Gas-fired thermal generation provides the bulk of today’s energy flexibility in the UK. Hydrogen can be used to displace natural gas as an input fuel and decarbonise this key source of flexibility.

Wholesale power markets

The Wholesale Market is the primary market for wholesale electricity trading between generators and suppliers. Electricity can be traded from years ahead up to one hour ahead of the delivery. Flexible technologies such as batteries and gas reciprocating engines are mainly targeting short-term trading by providing real-time flexibility to help balance the system. Therefore, they trade mainly in day-ahead to intraday markets.

  • Day-ahead hourly, half-hourly and intraday auctions

  • Within-day power markets on the intraday exchange

Services

Frequency response

Providers are awarded an availability payment at different contract durations. Fast-responding technologies such as batteries are best suited to provide services in real time.

Dynamic Containment (DC), Dynamic Moderation (DM) and Dynamic Regulation (DR): A new suite of products used by National Grid. It is a fast-acting service (DC for post-fault management and DM&DR for pre-fault) to ensure frequency remains within the statutory range of +/-0.5Hz in the event of sudden demand drop or supply surge on the grid.

Firm Frequency Response (FFR): FFR is a real-time continuous frequency balancing service, managing system frequency deviations on a minute-by-minute basis.

Services

Capacity Market

Two auctions are held yearly to disburse capacity contracts 1 and 4 years ahead of delivery for keeping generation capacity ready for response.

Providers are paid an availability payment for being connected. New build generators can apply for a 15-year contract in the T-4 auction while existing generators or those able to reduce demand can apply for a one-year contract in the T-1 auction. To ensure delivery, there are stringent rules to prequalify and meet the various milestones required to participate in the Capacity Market. 

All of Statera’s assets are designed to deliver this reserve service to National Grid.

Balancing Mechanism

This is to respond to events including power station trips, demand surges and intermittent renewable generation. Flexible technologies such as batteries and gas reciprocating engines are well placed to provide real-time flexibility in the BM to help.
