My Lords, I am grateful to the noble Lord, Lord Oxburgh, and my noble friend Lord Jenkin for prompting the debate on gas storage. The noble Lords’ proposal is timely, coming precisely as the Government are thinking about these issues. The GB gas market is one of the best functioning and most liquid in the world, and has brought forward significant investment in the past decade. This has expended our infrastructure to the point where our input capacity alone can meet 189% of our annual needs, and it has spare capacity to respond flexibly to price signals to deliver gas to our market from a diverse range of sources and routes. It has also increased storage in terms of overall capacity, where we have seen a 25% increase in the past decade, and even more so in terms of deliverability—the amount of gas that can be delivered to the grid each day to cope with volatile demand. Once two recently completed fast-cycling storage projects are counted, along with a further two projects under construction, storage deliverability has doubled in the past 10 years. The growth in input, capacity and flexible storage delivered by the market provides the additional flexibility we will need to help meet variable demand for heating requirements on peak winter days in severe weather conditions, or for the power sector, where gas is likely to be called on to respond flexibly to intermittent generation sources such as wind.
The Government are not complacent or averse to making appropriate legislative changes to improve our gas security. Indeed, it was part of our coalition agreement to do so. In relation to gas security, the Energy Act 2011 conferred on Ofgem new powers to sharpen the incentives on gas market participants to secure gas supplies. Ofgem has been consulting on potential reforms and is due to announce its final proposals very shortly. We are also working within the EU to ensure adoption and implementation of a variety of measures to enhance gas security through a well functioning, integrated and transparent European gas market. For example, the implementation of the third energy package has already improved market integration across the EU, so that storage in other countries such as Germany can respond to price signals sent by our own market. In addition, the development of common gas codes provided for by the third package will facilitate further gas trading across borders according to pricing signals. The EU regulation on security of gas supply requires member states to undertake regular assessments
of their gas security and prepare plans to mitigate the risks they face, as well as meeting supply and infrastructure standards.
New investments in physical infrastructure are being made available to enable gas to flow more freely around the EU. In addition, DECC is working to maximise sustainable gas production from our North Sea and unconventional gas resources. Furthermore, the Government have been conducting a detailed review of whether further reforms—in addition to those being considered by Ofgem—might be appropriate and we intend to announce our decision in the coming weeks. In reaching a decision, the Government will consider the physical and price security arguments for intervening in the markets and whether any of the potential interventions provide a cost-effective means of improving the security of our supply. Therefore, the Government may conclude that the interests of consumers are best served by not intervening in the market.
However, our assessment is that all measures being considered—these include the measures to promote gas storage envisaged by this amendment—can already be implemented using existing powers. In particular, Ofgem has powers under Section 7B(4)(a) of the Gas Act 1986 to introduce such licence conditions as it considers necessary or expedient, having regard to Ofgem’s duties, which include the promotion of the security of supply. It would also be possible for the Secretary of State to make a direction under Section 7B(5)(a) of the Gas Act 1986 setting out licenceholder obligations. Additionally, Ofgem can apply for an order to be made by the Secretary of State under Section 41C of the Gas Act 1986 to make a new activity such as gas storage a licence activity. Such an order made by the Secretary of State may also provide any consequential changes to primary and secondary legislation.
The noble Baroness, Lady Worthington, asked about the role of renewable gas. The Government have plans to maximise the production of gas from all sources: conventional, shale and renewable. She also asked whether the regulator considers vertical integration and impacts on pricing. Yes, Ofgem considers the impact on pricing in all its regulatory functions. Therefore, the Government do not consider these amendments necessary and I hope that, having found my explanation reassuring, the noble Lord, Lord Oxburgh, will withdraw his amendment.
