Where Does My Energy Come From?
Where Does My Energy Come From?
It’s a simple question, but the answer is more complex than many businesses realise.
When you flick a switch or power up your operations, the electricity and gas you use is the end product of a vast, interconnected system of generation, infrastructure, global markets and regulation. Understanding where your energy comes from isn’t just a curiosity, it’s commercially relevant.
Electricity: A Real-Time Balancing Act
In the UK, electricity is generated from a mix of sources. The primary contributors today include:
- Gas-fired power stations
- Wind (onshore and offshore)
- Nuclear
- Solar
- Interconnectors importing power from Europe
Unlike gas, electricity must be generated and consumed in real time. Supply and demand are constantly balanced by the system operator, ensuring the grid remains stable. If supply ever falls short, then prices can spike. In recent years, numerous grid updates have taken place to ensure that renewable energy can be added to the grid and quickly transported.
While many businesses purchase “renewable” tariffs, this doesn’t mean the electricity you receive was generated by renewable sources. Electricity on the grid is pooled, so you don’t receive electrons directly from a specific wind farm. Instead, suppliers match your usage with renewable generation certificates (REGOs), demonstrating that an equivalent amount of green power has been produced.
For larger energy users, the mix of generation matters because it directly impacts wholesale pricing. An evening with low wind output, for example, can significantly increase reliance on gas-fired generation, therefore increasing exposure to the wholesale price of gas.
Gas: A Global Commodity
Gas plays two roles in the UK energy system: Heating homes and businesses directly, and fuelling many power stations that generate electricity.
The UK produces some natural gas domestically from the North Sea, but production has declined over the years. Today, a significant proportion of supply is imported via:
- Pipelines from Norway
- Liquefied Natural Gas (LNG) shipments – particularly from Qatar and the US
- Interconnectors from continental Europe
Because gas is traded globally, UK prices are influenced by international supply and demand dynamics. Events in Europe, Asia or the US can directly affect what UK businesses pay. This means geopolitical events such as the threat of war in the Middle East can cause prices to rise sharply.
Renewables and the Energy Transition
The UK’s generation mix has changed dramatically over the past decade. Coal has been phased out, while wind and solar capacity have grown significantly.
This shift brings both opportunity and volatility. Renewable generation lowers carbon intensity and reduces exposure to fuel imports. However, because wind and solar output depend on weather conditions, short-term price fluctuations have become more pronounced.
For businesses with flexible procurement strategies, understanding this dynamic can create opportunities to secure more competitive pricing.
Why It Matters for Your Procurement Strategy
Where your energy comes from can influence many other aspects of your energy strategy, including:
- Wholesale market pricing
- Carbon reporting obligations
- Contract structures
- Long-term risk exposure
Understanding where your energy comes from has never been more important for UK businesses.
