With permission, Madam Deputy Speaker, I shall make a statement about the review of electricity market arrangements.
The central challenge that we face is the urgent need to get off expensive, insecure fossil fuels and to deliver an energy system that meets at least double the level of current electricity demand by 2050. In doing so, we need to design the electricity network to ensure that infrastructure is built in the right places, so that we can effectively provide power where it is required. As a result of previous failures to do so, power now goes to waste, costing consumers in higher bills. That is one reason why reform is needed.
The task of this review is to help deliver a fair, affordable, secure, and efficient clean power system. The key question has been whether to proceed with zonal pricing or a reformed national system. Under zonal pricing, we would split the country into different zones relying on price differentials to guide investment decisions. Under a reformed national price system, we would rely on more deliberate strategic co-ordination in advance of investment—planning our network and areas of intended generation more closely and then delivering.
I have applied three tests to this choice in the time since the Government took office: first, what is the fairest approach for families and businesses, both now and in the long term; secondly, which reform can deliver energy security and will best protect consumers and ensure bills savings as soon as possible; and, thirdly, what will do most to ensure the investment, jobs, and growth that we need across the economy? On the basis of these tests, I have concluded that the right approach is reformed national pricing. Let me set out why.
On the fairness test, under reformed national pricing, there would be one national wholesale price, as now. As I have said, under zonal pricing there would be different wholesale prices in different zones. Lower prices will tend to occur in zones with more renewable energy and a smaller population, and higher prices in those with less power and more people.
This would be a significant departure from the current system, which, while it has some differences in network costs, means that wherever a person lives, they pay the same wholesale price for each unit of electricity. The challenge will be obvious to the House. People and businesses could find themselves disadvantaged through no fault of their own and many would see that as unfair. Such a postcode lottery is, in my view, difficult to defend.
The Government have considered whether it would be possible to mitigate these effects under zonal pricing. We have concluded that, while it might, it would be a very complex and uncertain process. And it would be even more challenging to do so for large businesses, given the way that they purchase electricity. Therefore, firms in higher priced zones, such as the midlands, Wales, and the south of England, would therefore face damage to their competitiveness. That is why we have seen so many business groups express such concern about zonal pricing. Indeed, today’s decision has already been welcomed by UK Steel, Make UK, the British chambers of commerce, Ceramics UK and others.
The next test that I applied is which system can best help deliver energy security, protect consumers and ease the cost of living crisis as soon as possible. Long-term reform is essential to cut costs and save money for consumers compared with the status quo, but there is a key question as to what happens in the meantime. The clear advice of my Department is that moving towards zonal pricing would take around seven years to complete in full—assuming no delays. Over that seven-year period, the costs of financing essential investment in our energy system would be likely to rise to accommodate investor uncertainty, at a moment when we urgently need to replace retiring assets and build a clean energy system to boost our energy security. This risk premium would be paid for by consumers in higher bills in the coming years. There is also a danger that it would leave us stuck on fossil fuels for longer by deterring investors from bringing forward the investment that we need for our energy security.
By contrast, reformed national pricing could be delivered more quickly and at lower risk. Indeed, some elements of a reformed national pricing system are already under way, including building network infrastructure, and we intend to proceed with other measures, such as reform of transmission charges, as soon as possible in this Parliament. Having studied this in detail over months, I see real risks that zonal pricing would deter the investment we need and that bills would rise in the transitional period.
The third test is the investment and growth we need as a country. Many businesses make decisions to invest based on the energy costs that they face. The industrial strategy took a crucial step forward in lowering the costs faced by businesses, and clean power will help get us off the fossil fuel rollercoaster, which has so damaged our country’s businesses.
We know that the biggest enemy of business investment is uncertainty, and the risk of zonal pricing is that it would create very significant uncertainty. Imagine a business seeking to invest not knowing for a number of years what zone it would be in and what price it would pay. This would harm investment not just in the energy sector but well beyond it, and it would inevitably risk reducing investment in our country precisely when we need it and undermining the tens of thousands of good jobs in constituencies across the country that our clean energy mission will support.
On the basis of those three tests, I believe that the best choice is to proceed with reformed national pricing. The key elements will include: effective planning through the strategic spatial energy plan to be published next year; national pricing reforms, such as making transmission charges more effective and predictable and taking relevant powers through Parliament to do so; and making changes working with the National Energy System Operator and Ofgem to improve the operation of flexibility and the balancing of markets.
Under reformed national pricing, we will build the transmission network we need to the benefit of all consumers, and we will be more directive and co-ordinated in how we plan our energy system. Each upgrade that we deliver will reduce constraint costs and ensure that consumers benefit from clean power. My Department will set out a reformed national pricing delivery plan later this year. Taken together, I believe that these steps can help to deliver a more affordable, fair, secure and efficient energy system and will address the problems that the REMA process set out to solve without the unacceptable risks I have outlined.
These steps build on what we have done over the past year to turbocharge our drive to home-grown clean power. We have consented three times more solar in 12 months than in the previous 14 years. We have lifted the onshore wind ban and consented enough offshore wind to power the equivalent of 2 million homes. We have backed the biggest expansion of new nuclear in half a century. We are kick-starting new industries in carbon capture and hydrogen. We are giving nearly 3 million extra families £150 off their energy bills next winter and upgrading up to 5 million homes to help cut bills.
Every energy decision that this Government make is in pursuit of protecting the British people from fossil fuel markets controlled by petrostates and dictators by delivering clean, home-grown power that we control. It is in that spirit that we have chosen reformed national pricing. We are doing everything we can to ensure energy security, protect consumers and get bills down, and to ensure that businesses can invest for the future. This is underpinned by a commitment to fairness across the country. I commend this statement to the House.
