Baroness Taylor of Stevenage (Lab)

I thank the noble Baroness, Lady Pinnock, and the noble Lord, Lord Jamieson, for their contributions to this debate on the SI. I shall try to address all their questions; if I miss any, I am sure that they will let me know, and I shall respond in writing to them. First, to pick up on the issue of the publication of the national policy statement, which I know is a concern that both noble Lords have expressed, we do not anticipate any significant gap between the SI coming into force and the publication of the draft national policy statement. If for some reason the gap is more pronounced, any projects subsequently directed into the NSIP regime will be considered in the same way as any other business or commercial project under Section 105 of the Planning Act 2008. When the NPS arrives, it will set out which types of data centre infrastructure are considered of national significance—I think that is an issue that the noble Lord, Lord Jamieson, raised. That includes details of any thresholds and parameters, such as size or other relevant factors, as well as relevant policy background—including the needs case for data centres. The national policy statement is currently under development and testing. Given the time it may take to comply with statutory requirements for the designation of a new national policy statement, it was considered appropriate to lay the statutory instrument in advance, because we know how quickly this industry is moving and we want to make it possible to deliver data centres as quickly as we can. The proposed national policy statement for data centres will be the very first national policy statement to be prepared covering a prescribed type of business or commercial project. We are working on that at speed. If there is no national policy statement in place, the Planning Act 2008 will apply, as I said. I hope that that clarifies when we are expecting that to come forward. I know that the noble Lord, Lord Jamieson, also mentioned grid capacity. He knows that I have been working very closely with DESNZ colleagues—I do not have the net zero brief anymore, but I continue to take a great interest in this. My colleagues in DESNZ understand that grid capacity is not just an issue around data centres; it affects the whole construction industry. We need to move at pace to make sure that we have grid capacity to meet needs going forward. DESNZ is actively working on that, and I am sure it will make further announcements in future on that subject. The noble Baroness, Lady Pinnock, mentioned some issues around the environmental sustainability of the impacts of data centres. They are important, and, of course, it is important that we make sure that the NSIP regime does not diminish them, as in comparison with the TCPA regime. Both planning regimes are governed by the same underlying principles to ensure that environmental effects from the proposals that come forward are identified and considered clearly as part of the application and decision-making process. The underlying legal and policy frameworks are different. For NSIPs, where a national policy statement has effect, the first port of call for decisions is in the context of the relevant national policy statement. Under the TCPA regime, local authorities decide planning applications in accordance with the local development plan, as we all know. That is the substantive difference between the two, but it should not undermine the environmental aspects being taken into consideration. The extent to which a proposed data centre NSIP would have environmental impacts, both positive and negative—including water and energy consumption, noise pollution, waste generation, land use, visual impacts and location—would be part of the consideration of the NSIP during its examination and its determination by the Secretary of State. Prescribed statutory bodies, such as the Environment Agency, Natural England, the Forestry Commission and the Canal & River Trust, play an important role in that examination. They must be notified of accepted applications and invited to a preliminary meeting, and they are entitled to make oral representations at hearings. Environmental impacts are considered as part of the development consent order process, and the 2017 environmental impact assessment regulations set out the procedures for determining whether a proposed development requires the applicant to undertake an environmental impact assessment. Many large business or commercial projects, which will now include data centres, can be caught by the EIA regulations. An EIA is a process where the likely significant environmental effects are assessed and taken into account, and, where applicable, an applicant must submit an environmental statement as part of their application to the Planning Inspectorate. The emerging national policy statement on data centres, like any national policy statement that is being developed, will need to be supported by an appraisal of sustainability which takes account of the environmental, social and economic effects of designating an NPS and reasonable alternatives, sets out mitigation and enhancement measures and helps inform the preparation of the national policy statement to promote sustainable development. Habitats regulations also apply to an NPS on habitats sites. I have gone into that in some detail because I want noble Lords to understand that there is significant environmental protection, regardless of which route through planning data centres take. The noble Baroness, Lady Pinnock, mentioned heat. Data centres produce significant heat; the technology exists to capture that and use it in district heating networks or to meet significant demand. I hope that, increasingly, as this industry develops, there will be more creative and imaginative uses for that heat. There is potential for it to be captured and used for further benefit and there have been successful examples of using data centre heat for hospitals and homes. A current UK example, if she is interested, is the use of a data centre to heat a local swimming pool in Devon. That is very good news. The Greater London Authority is developing a pilot to test heating up to 10,000 homes and at least one hospital—Middlesex—from London-based data centres. We are engaging with developers and operators to determine whether further interventions are necessary and appropriate to encourage that sort of take-up of recycling the heat.
