My Lords, I am grateful to the noble Lord, Lord Oxburgh, for his amendment, which returns to the matter of gas storage that he raised in
Committee. My department published analysis and made a Statement in the other place on 4 September on precisely this issue and I am glad to discuss it today.
The amendment is intended to enable the Secretary of State to make arrangements to provide capacity payments in exchange for the supply of gas more securely, or at lower prices, than would otherwise be possible. I should make it clear from the outset that the capacity market is not intended to support the gas market. Rather, the capacity market is an integral part of our electricity market reform programme.
On the face of it, this amendment aims to facilitate a simple and attractive concept: cheaper and more secure gas for consumers. While the Government recognise that rising energy bills are a worry for many households and businesses, this amendment is not the solution. It is difficult to imagine that any supplier of gas would sign a contract to sell gas at a future date at a discount to the prevailing market price. The capacity payment is required to offset the risk to the supplier of being out of pocket and it would need to top up any shortfall to the point where there would be no net benefit to consumers.
Specifically, it has been argued that capacity payments may facilitate the construction of additional gas storage capacity, which offers the potential to buy cheaply in summer and store the gas until it can be sold when prices are higher in winter, as the noble Baroness, Lady Worthington, pointed out. This is a service that the market currently provides. Storage capacity is currently increasing, with two facilities having been completed in the past 18 months and two more facilities under construction. There are 10 more projects with major planning consents in place, which are awaiting the right commercial signals to invest. Where the market is not already providing this signal, supporting a storage project through subsidy, whether by a capacity payment or other means, would just transfer the risk currently faced by the market to the Government. In other words, it would be passed on to consumers and taxpayers.
DECC considered in detail the case for supporting gas storage. Analysis shows that, although there are interventions that could enhance our gas security, under most scenarios they would not do so cost-effectively. All options risk adding disproportionate costs to energy bills and risk distorting a well functioning GB gas market. We will not be taking these interventions forward and do not envisage needing the powers that these amendments propose.
As I explained earlier, we are introducing a capacity market to provide for capacity payments to ensure security of our electricity supplies. This is because the electricity market faces new challenges. These include the planned closure of a large proportion of our existing generating capacity and an increased amount of low-carbon generation. That means that there is an increased need for additional reliable capacity. The capacity market is specifically designed to address this.
These issues do not translate to the gas market. The security of gas supply outlook is robust. There is spare supply capacity: the available capacity of nearly 700 million cubic metres a day is far in excess of even the highest recorded daily demand of 465 million cubic metres. The gas system also has greater flexibility to rectify
demand/supply imbalances within the balancing period and, for gas, unlike electricity, there are readily available means for storage which the market is currently expanding. The Government therefore do not consider this amendment to be necessary. I hope that the noble Lord, Lord Oxburgh, has found my explanation reassuring and on that basis will withdraw his amendment.
