Key UK Energy Infrastructure Trends for 2026
- Market-Wide Half-Hourly Settlement (MHHS) rollout
- Rising non-commodity charges
- Grid modernisation investment
- Growth in renewable generation
- AI and digitalisation
- Government-backed energy reforms
The Era of Smarter Settlement is Here
What was once considered a future milestone has now taken centre stage in today’s energy dynamics. The Market-Wide Half-Hourly Settlement (MHHS) will replace the traditional methods, which rely on estimates and averages of overall energy consumption. This requires energy suppliers in the UK to calculate how much energy is consumed by each customer by using the half-hourly electricity consumption insights.
This programme, driven by Ofgem and delivered by Elexon as Senior Responsible Owner, will offer a clear picture of electricity usage across the UK, modernising how electricity is used and reformed.
What MHHS Means for Businesses
- More accurate billing
- Better visibility of energy use
- Easier participation in flexibility schemes
- Greater value from smart meters
- More opportunities to reduce energy costs through demand shifting
MHHS will deliver net benefits ranging from £1.6 to £4.5 billion for energy customers in Great Britain from 2021 to 2045, putting customers at the heart of a fair and more energy-efficient energy system, says Ofgem.
MHHS represents a major milestone in the development of a smarter and more resilient UK energy Infrastructure system. This programme will benefit everyone involved, including customers, energy suppliers, and the energy sector as a whole.
AI is Increasing Electricity Demand
The rapid growth of artificial intelligence (AI) is transforming industries, but it is also creating unprecedented demand for electricity. AI-powered data centres require vast amounts of energy to process, store, and analyse large volumes of data while supporting advanced computing applications. As more organisations adopt AI technologies, electricity consumption from data centres is expected to rise significantly.
This increasing demand is placing additional pressure on the UK’s electricity network, accelerating investment in transmission infrastructure, grid capacity, and smarter energy management systems. It also reinforces the need for greater flexibility within the energy system to balance rising demand with the growing share of renewable generation.
For businesses, this means continued investment in grid modernisation, increasing emphasis on energy efficiency, and greater opportunities to benefit from smart technologies, flexible energy usage, and demand-side response programmes as the UK adapts to a more digital and energy-intensive future.
Rising Non-Commodity Charges
Non-commodity charges are becoming a dominant aspect of UK energy bills, often overshadowing the cost of energy itself. These non-energy costs, which are compulsory charges added to your energy bills, fund the infrastructure maintenance, electricity transmission, and government policies that support the net-zero transition.
To your surprise, these charges now account for up to 60% of your energy bills, largely impacting operational expenses and budget management. Understanding these charges, which account for a significant part of your energy bills, is no longer an option; it has become essential to manage overhead costs.
Why Have Non-Commodity Charges Increased?
The rise in non-commodity charges reflects the UK’s long-term investment in building a cleaner, more secure, and resilient energy system. As the country transitions towards net zero, enormous funding is required to modernise ageing infrastructure, expand electricity networks, and integrate increasing volumes of renewable energy.
At the same time, investment in grid reinforcement and energy security has become a priority to ensure the network can support growing electricity demand from electrification, digital technologies, and emerging sectors such as AI-powered data centres. While these investments strengthen the UK’s energy infrastructure, many of the associated costs are recovered through non-commodity charges included in business energy bills.

Grid-related Costs
Policy Levies
Under the Modern Industrial Strategy, the UK is taking significant steps to support energy-intensive industries through the British Industry Supercharger (BIS) and the British Industrial Competitiveness Scheme (BICS – scheduled for 2027) to address rising non-commodity charges.
But here is the catch. This programme only covers a small portion of companies, while the majority of businesses are still affected by rising energy costs.
Proven Decarbonisation Strategies and A Green Reality
The UK energy landscape reflects a strong commitment to increasing reliance on renewable energy and reducing carbon emissions. With ambitious targets of producing 95% clean energy by 2030, the UK is making impressive progress. Acceleration of renewable energy projection, modernisation of grid infrastructure, and development of market reforms lay the foundation for long-term sustainability and pave the way towards a greener future.

Development in Energy Infrastructure
Among the UK’s major achievements in the adoption of renewable energy is the launch of the Cleve Hill Solar Park, the largest operational facility in the country. Offshore wind energy remains a cornerstone of decarbonisation, with onshore wind emerging as a cost-effective approach to meet rising demand. At the same time, investments in advanced technologies, including AI-powered maintenance and digital twins, are increasing the efficiency and reliability of the energy systems. The rapid growth of renewable energy has emphasised the importance of grid modernisation, which is addressed by a £28 billion investment package announced by Ofgem. This investment aims to upgrade and strengthen Britain’s energy network, improving energy security and enabling the transmission of more clean energy from renewables.

Market Reforms and Policy Initiatives
Beyond infrastructure development, the UK is undergoing a pivotal shift in the energy market. The introduction of Great British Energy (GBE) as a government-backed initiative reflects proactive support for clean energy. Market reforms such as MHHS and revised network levies incentivise more sustainable and adaptable energy use.
By resourcing around 69% of the nation’s energy from renewable energy resources, the UK is steadily moving away from fossil fuels. A powerful signal of the UK’s commitment to decarbonisation and long-term sustainability.
