DECARBONIZATION AGENDA FOR THE UNITED KINGDOM
The UK’s Electricity Decarbonization Agenda aims to switch from Fossil Fuels to Renewable Sources like Wind, Solar, and Nuclear, with Hydrogen and Carbon Capture and Storage (CCS) also playing a role.
The Target is to Fully Decarbonize the Power System by 2035, while also meeting an Expected Increase in Electricity Demand.
This will require a Major Upgrade of the Electricity Grid and Significant Investment in New
Technologies and Infrastructure.
Key Aspects of the UK’s Electricity Decarbonization Agenda:
TARGET:
Fully Decarbonize the Power System by 2035, Subject to Security of Supply.
LOW-CARBON SOURCES:
Increase Reliance on Renewable Energy Sources (Offshore and Onshore Wind, Solar, Nuclear), and hydrogen, including Gas with CCS.
GRID UPGRADE:
Major Upgrades to the Electricity Grid are needed to Connect New Low-Carbon Generation and Support the Increased Electricity Demand.
INVESTMENT:
Significant Public and Private Investment in New Generating Capacity and Infrastructure is Required.
ENERGY DEMAND:
Manage an Expected Increase in Electricity Demand as more people switch to Electric Vehicles and Heat Pumps.
FLEXIBILITY:
Develop a Flexible and Responsive Power System that can adapt to Changes in Demand and Generation.
TECHNOLOGY:
Explore and Utilize New Technologies, such as Energy storage and Smart Grid Technologies, to Optimize the Electricity System.
COLLABORATION:
A Collaborative Approach Involving Government, Industry, and cCnsumers is needed to Ensure a Smooth and Cost-Effective Transition.
THE PATH TO CLEAN POWER BY 2030
Successful delivery will require Rapid Deployment of New Clean Energy Capacity across the whole of the UK, reflecting the Shared Renewable Ambitions of the UK, Scottish and Welsh Governments.
In this Plan, we are accepting Government’s Central Role in steering the Creation of this New Energy System, setting our Expectations for the 2030 Capacities of Key Technologies at National and Regional Level.
We have High Ambition. That means 43-50 GW of Offshore Wind, 27-29 GW of Onshore Wind, and 45-47 GW of Solar Power, significantly reducing our fossil-fuel dependency. These will be complemented by Flexible Capacity, including 23-27 GW of Battery Capacity, 4-6 GW of Long‑Duration Energy Storage,
and Development of Flexibility Technologies, including Gas Carbon Capture Utilisation & Storage, Hydrogen, and Substantial Opportunity for Consumer-Led Flexibility.
In line with NESO Advice, this New Capacity must be Underpinned by the Rapid Delivery of 80 Network and Enabling Infrastructure Projects, most of which are already at an Advanced Stage of Planning and Development.
Over the Period to 2030, Security of Supply will be Protected with the Maintenance of an Expected 35 GW of Unabated Gas Reserve Capacity.
Delivering Clean Power 2030 also Paves The Way to Decarbonising the Wider Economy by 2050, as we pursue the Electrification of Heat in Buildings, Transport, and Industry. By 2050, Annual Electricity Demand is likely to AT LEAST Double.
Clean power by 2030 Prepares Us for the Rapid Growth in Power Demand Expected Over the 2030s and 40s.
