The way electricity is settled across Great Britain is changing, and that change could make the shape of a business’s electricity demand increasingly important. Market-wide Half-Hourly Settlement (MHHS) is now being rolled out across the electricity market. Migration began in October 2025 and is scheduled to complete in May 2027. At its simplest, MHHS means...
The UK Government’s latest announcement to reduce the influence of gas on electricity prices is a welcome and necessary step. Its plan includes voluntary long-term fixed-price contracts for existing low-carbon generators, alongside an increase in the Electricity Generators Levy from 45% to 55%. The stated aim is clear: reduce the share of electricity still exposed...
As conflict in the Middle East intensifies, gas markets are reacting in exactly the way energy users have come to fear: sharp price increases, rising volatility and renewed concern over future electricity costs. For UK businesses, public sector organisations and energy-intensive sites, that raises a familiar and frustrating question: if the UK is generating more...
For a decade, “net zero” was technocratic shorthand for cleaning up the energy system without tanking the economy. In 2024–25, the phrase morphed into a political lightning rod. In the UK, Reform UK framed net-zero policy as a driver of higher bills and red tape; their 2024 “Contract with You” promised to scrap green levies...
As revealed at All Energy 2025, OnGen is delighted to announce its partnership with SystemsLink to help its customers decarbonise their estate through onsite renewable energy generation whilst reducing energy costs.
What is Biomass Heating? Biomass heating is a renewable energy source that uses organic materials to generate heat. The most common fuels for biomass heating include wood pellets, wood chips, logs, and agricultural waste. Biomass boilers burn these materials in a specially designed combustion chamber to produce heat, which can be used for space heating,...
The UK faces a classic energy trilemma – the challenge of delivering low-cost, low-carbon energy while ensuring security of supply (The World Energy Trilemma). In recent years, this balancing act has become more precarious. Geopolitical upheavals and spiking fuel prices have jolted energy security to the forefront of public concern, after decades when it was...
Not only does generating energy from renewable sources reduce an organisations scope 2 emissions (scope 3 of their customers) but they also make great financial sense when sized correctly. The financial benefits consist of energy cost savings and revenue generating opportunities such as grid services, and market-based incentives. By combining 2 or more of these...
What is the Smart Export Guarantee (SEG)? The SEG is an initiative implemented by the UK government in 2020 which rewards households and small businesses for selling their surplus electricity back to the national grid. This replaced the Feed-in-Tariff (FiT) scheme which ended in 2019. The SEG exists to incentivise generating power through renewable energy...
Understanding Non-Commodity Costs in Energy Non-commodity costs are distinctly separate from commodity costs and relate to the delivery of energy to the consumer. These include transmission charges, distribution charges, and environmental levies imposed by the government. Generally speaking, the commodity cost will be tied to the current market rate and non-commodity costs are passed through...
