Electricity Supply in the UK industry analysis
The Electricity Supply industry has developed considerably since its liberalisation in 1999. Following a period in which the Big Six suppliers dominated, energy regulator Ofgem endeavoured to introduce greater competition to the market as part of attempts to drive down energy bills. Major mergers and acquisitions effectively brought the dominance of the former Big Six suppliers to an end at the end of 2019-20. Along with weakening electricity consumption, swelling competition has applied further pressure on revenue in recent years.
Trends and Insights
- Surge in wholesale prices causes industry shake-up. A steep rise in wholesale electricity prices led to the collapse of numerous energy suppliers during the energy crisis; leading to a power shift in the market and renewed dominance of major suppliers.
- Gas holds sway in UK's power generation. While the UK extensively banks on gas-fired power stations for electricity, surging wholesale gas prices and geopolitical tensions have ignited efforts to diversify the energy mix.
- London and the South East lead the UK's electricity consumption. This is mainly due to the capital's densely populated commercial premises and the South East's large local population, which has increased domestic electricity use.
- Rigorous financial checks bolsters energy market resilience. Ofgem has tightened entry requirements, necessitating potential entrants to exhibit significant financial stability for loss absorption and to meet capital requirements.
