I share my noble friend’s keenness that we should, as a country, take advantage of this growth market. I do not have the figures at my fingertips, so if I may, I will write to him.
The noble Lord, Lord Grantchester, asked how the regimes compare between ourselves and the devolved Administrations. They are essentially the same across the United Kingdom. My officials have worked closely with those in the devolved Administrations to ensure this.
The noble Lord asked when the guidance will be ready. The Environment Agency and Natural Resources Wales have developed cost-benefit analysis guidance to assist operators, which will be published shortly. The draft guidance was subject to consultation last year. He also referred to what he saw as a gap in the impact assessment. There is uncertainty regarding how many of the operators within the scope of this instrument would have undertaken a cost-benefit analysis without the requirement being added to their environmental permit. The outcomes, including the environmental benefits through reduced carbon emissions, will be site-dependent and will depend on operators’ decisions about how to proceed. They are therefore impossible for us to quantify at this stage. However, the impact assessment provides a number of case studies to which I referred in my opening remarks.
The noble Lord asked a question related to my noble friend’s point on how big the potential is for combined heat and power in this country. The analysis by the Department of Energy and Climate Change estimates that the total technical potential for CHP in the UK is about 13 gigawatts by 2020, of which
7.8 gigawatts is projected to be economically viable by that date. The majority of this is likely to be natural gas-fired. DECC’s final Electricity Market Reform Delivery Plan projects up to 600 megawatts of biomass CHP being deployed by 2020. The regulations will help to unlock this capacity.
The noble Lord, Lord Grantchester, asked me another question. DECC’s research suggests that there are barriers which these regulations would address, such as a lack of awareness of CHP or the in-house expertise to assess potential projects. I hope that this response has answered most of the questions put by the noble Lord, and to the extent that it has not, I will of course write to him.
