The UK has committed to decarbonising the electricity system by 2035 and reaching net zero by 2050 – with home-grown, green technologies key to supporting the transition away from fossil fuels.

As a uniquely integrated energy company, we have a significant role to play in helping achieve this.

Operating through the entire energy value chain, we work on some of the most exciting initiatives in the industry, helping people and organisations tackle their toughest energy challenges.

Today we manage 15GW of assets - twice the size of the UK's nuclear fleet - with around 80% of them being clean power sources like wind and solar, but that's not enough.

Exploring everything from solar farms and battery storage to hydrogen ready backup generation – we're leaving no stone unturned to build a cleaner, greener future for the UK.

Here are some of the ways we’re transforming the energy industry and helping the UK and Ireland reach net zero:

Leinster Solar Farms

Bord Gáis Energy has partnered with Neoen on three solar farms across Leinster bringing 58MWp of power to the grid and powering over 12,700 homes.  

Once complete, they’ll be among the first utility scale solar plants in Ireland and will add to Bord Gáis Energy’s increasing sources of renewable supply being made available to their customers.

Glen Dimplex Smart storage heater trial

We’re working with Dublin based Glen Dimplex to install smart storage heaters into 375 homes as part of a trial in to how they’ll operate as part of a virtual power plant.  

They will work in line with renewable energy, holding onto spare green electrons when in surplus - and pausing that energy harvesting when demand threatens to outstrip supply.

This will help reduce energy wastage and create a more flexible energy supply.

Case study

Dyce battery Storage

The Dyce Battery Storage Project aims to reduce the need to switch off wind turbines, when they threaten to overload the grid. Payments to switch off wind turbines have totalled nearly £600m over the last three years, so finding a way to store those lost electrons makes environmental and financial sense.

Located near a connection for offshore North Sea wind farms, the Dyce Battery will store enough clean energy to power 70,000 homes for an hour - and help improve the UK’s energy security.

Net Zero Consultancy at Biomar

Centrica Business Solutions delivered a science-based pathway to Net Zero for BioMar’s Scope 1 and 2 emissions, helping them deliver it as cost effectively as possible. 

Case study

Roosecote Battery Storage

Battery storage facilities like Roosecote provide the grid with the stability and flexibility needed to move towards more renewable energy sources.

Previously a coal-powered station, Roosecote is one of Europe’s largest battery assets and holds enough power to meet the needs of around 50,000 homes for around half an hour.

Hydrogen Storage at Rough

Hydrogen has a key role to play in helping the UK move to alternative fuels and improving energy security.

Centrica’s Rough facility has stored gas safely for three decades - and could be transformed to store enough hydrogen to heat every home in the UK for 10 days.

Brigg Battery Storage

Centrica Business Solutions is converting the decommissioned Brigg gas-fired power station into a battery storage facility capable of supplying the equivalent of a full day’s energy consumption for 11,000 households.

The 50MW /100MWh project will provide energy storage for the 168 wind turbines across Lincolnshire, maximising the potential of every megawatt of green electricity and providing vital resilience for the grid.

Whitby Hydrogen Village

Using hydrogen to power our homes could significantly reduce the UK’s CO2 emissions - and help the country reach net zero.

We’re working with Cadent at Whitby, which has been shortlisted to become the UK’s first ‘hydrogen village’ – which would see British Gas replace boilers and cookers in up to 2,000 homes free of charge, a major demonstration of the opportunity for hydrogen in the decarbonisation of UK homes.

Energy Efficient homes in Wales (Nest)

Supporting and educating people on energy efficiency at home is crucial to helping the UK reach net zero.

The Nest scheme in Wales, delivered by British Gas, offers free impartial advice and a package of free home energy efficiency improvements, such as a new boiler, insulation or solar panels.

Wye Valley Hospital

The NHS has set a target to reach net zero by 2045, Centrica Business Solutions works with dozens of trusts to reduce emissions across their estates.

At Wye Valley NHS Trust we installed a network of 47 ground source heat pumps each drilled 200m into the ground.

In addition, we’ve installed:

  • 3,170 low energy lights
  • 300 rooftop solar panels
  • 1,163 pipework insulation
  • 263 metres of pipework

Midland Heart Heat Pump

Our pilot trial with Midland Heart to decarbonise social housing in Coventry saw us showcase how housing stock can be retrofitted with lower carbon energy, including air source heat pumps, Mixergy cylinder, intelligent Hive heating control, optimised solar panels, new radiators, and pipework. 

Case study

Heat Pumps in Devon

Heat Pumps will play an essential role in the UK achieving its Net Zero goals by 2050.

Through a partnership with leading eco-technology provider Daikin, British Gas has begun fitting properties in Devon with the low carbon technology to help the customer lower their emissions, before rolling the new service out nationwide.

Codford Solar Farm

Construction on Centrica’s first 18MW solar farm is underway in Wiltshire - as part of our wider ambition to build a 650MW solar portfolio by 2026.

Solar has a key part in building energy security for the UK and supporting the transition to net zero.

Case study

Net Zero Homes with St Modwen

UK homes are responsible for around 20% of carbon emissions, so decarbonising how we heat them is vital.

British Gas is partnering with St Modwen Homes to deliver the first carbon neutral houses in the UK, designed to produce more energy than they consume.

Case study

Vodafone PPA

Power purchase agreements are one way that large businesses can meet their net zero commitments.

These agreements provide certainty to renewable energy developers by providing guaranteed returns for the power produced by their assets.

We supported Vodafone to sign a 10 year deal for the output of three solar farms with a total capacity of 110MW.

Case study

Power Purchase Agreements

As we transition to a renewable led grid, Power Purchase Agreements (PPA) play a vital role in supporting the growth of sustainable energy sources.

Centrica Energy Marketing & Trading is one of the leading providers of PPAs in Europe, allowing larger businesses access to demonstrably zero-carbon power, while providing renewable developers the financial certainty they need to continue building assets without the need for public subsidies.
