The Privatisation of Electricity

The Privatisation of Electricity: A Look Back

In 1990, the UK electricity industry underwent one of the most significant changes in its history. The Central Electricity Generating Board, which had been responsible for electricity generation and transmission across England and Wales for decades, was broken up and sold off to private investors. This was a significant restructuring of how electricity was generated, distributed and sold to households and businesses.

The CEGB was split into several new companies. National Power and PowerGen took over electricity generation, while the National Grid Company was established from the CEGB's transmission operations to oversee the high voltage network in England and Wales. At the same time, 12 regional electricity companies were created to handle local distribution and supply to customers.

For many people who lived through this period, it marked a noticeable shift in how they thought about their electricity supply. What had once been a state run service began transitioning to a market where electricity became a product sold by competing businesses.

Why Did Privatisation Happen?

The privatisation of electricity was part of a broader policy direction under the Conservative government led by Margaret Thatcher. The aim was to move away from state ownership of industries and towards a market based economy. This approach was applied across many sectors, including telecommunications, gas and water.

Several arguments were put forward at the time. State owned utilities were often subsidised by the government and did not operate at a profit. In some cases, they ran at a loss. Supporters of privatisation believed that private ownership would bring in investment, improve efficiency and reduce the burden on public finances.

There was also a political dimension. The sale of shares in these newly privatised companies was intended to spread share ownership among the public. Many ordinary people bought shares for the first time during this period, encouraged by advertising campaigns promoting the sales.

The government argued that competition would eventually drive down prices and improve service. However, full retail competition allowing domestic customers to choose their electricity supplier only began after 1998, eight years after the initial privatisation.

How the Market Has Changed Since

The electricity market today looks quite different from those early years of privatisation. The original companies have been bought, sold, merged and renamed many times over. Several are now owned by foreign parent companies, including firms based in France, Germany and Spain.

Customers gained the ability to switch suppliers, and for a time this did produce some competition on price. Comparison websites became a common way for households to find better deals. Ofgem, formed in 1999 through the merger of earlier regulatory bodies, was established to oversee the market and protect consumer interests.

However, the market has also experienced significant problems. The collapse of several smaller suppliers in recent years left many customers having to be moved to other providers. The energy price rises of 2022 and 2023 placed serious strain on household budgets and led to the introduction of government support schemes, including the Energy Price Guarantee which capped typical household bills. The government also provided direct payments through the Energy Bills Support Scheme.

The current structure of the market is often criticised for being too complex. Wholesale prices, network charges, environmental levies and supplier costs all contribute to what households pay, and it can be difficult for ordinary customers to understand where their money goes. Ofgem's price cap, introduced in 2019, now sets a limit on what suppliers can charge for default tariffs.

Was It the Right Decision?

Opinions on this question vary widely and often reflect broader views about the role of the state in the economy.

Those who support privatisation point to increased investment in the electricity network and the introduction of new technologies. The growth of renewable energy, while driven largely by government policy, has taken place within a privatised market structure. Some also argue that service reliability has been maintained despite growing demand.

Critics argue that essential services like electricity should not be run for profit. They point to high prices, executive pay at energy companies and the need for repeated government intervention during crises. The Labour Party has proposed bringing certain elements of the system back into public ownership, and the future structure of the National Grid remains a live political question.

What is clear is that energy policy continues to be a significant political issue, with discussions about price regulation, windfall taxes and the transition to net zero regularly appearing in the news.
