In its draft revised overarching policy statement, the government acknowledged that much of its plans to decarbonise the UK’s economy involves electrification, such as in the areas of transport, heat and industry, and that this in itself would likely result in more than half of the UK’s energy demand being met by electricity by 2050, up from just 17% in 2019. It said low carbon hydrogen would also be “likely to play an increasingly significant role” in ensuring the UK’s energy demands are met.
However, the government’s draft new policies not only focus on the desire to decarbonise but on the need to ensure that there is security of energy supply in the UK and that the cost of energy is affordable for end-users. It said the need for new energy infrastructure in this regard is “urgent” and has proposed that the UK’s energy infrastructure be made up of a mix of energy sources, including renewables, nuclear, low carbon hydrogen, residual use of unabated natural gas and crude oil fuels for heat, electricity, transport, and industrial applications.
A significant planned change to the national policy statement for renewable energy (EN-3) is the introduction of solar PV, technology considered unviable above 50MW when the original NPS was designated in 2011. Since then, the rapid advance in solar PV technology, falling costs and large transmission connection capacity becoming available due to conventional power plants being decommissioned, has resulted in a new era of “utility-scale” solar projects.
The 350MW Cleve Hill Solar Park, which received the first development consent order (DCO) for a solar nationally significant infrastructure project (NSIP) in May last year, paved the way for similar scale projects, including Sunnica Energy Park and Longfield Solar Farm, with a further 10 to15 currently at pre-application stage, ranging from 300MW to 1GW. The new EN-3 acknowledges that large-scale solar is now viable subsidy-free and at little to no extra cost to the consumer, and as such is a core part of the government’s strategy for low-cost decarbonisation of the energy sector.
Renewable energy expert Gareth Phillips of Pinsent Masons said: “There is much in the proposed new renewable energy national policy statement for solar developers to be enthused about. BEIS has drawn upon key themes from the Cleve Hill Solar Park DCO and cemented them in the new policy.”
“The acknowledgement that installed export capacity should not be seen as an appropriate tool to constrain the impacts of a solar farm, the importance of grid connection capacity and that agricultural land type should not be a predominating factor in determining site selection, and that applicants may seek flexibility for the installation of energy storage, with the option to install further panels as a substitute, are all important features of the new policy. So too the clear statement that for the purposes of determining the NSIP threshold of 50MW, a solar park’s capacity should be measured in AC, ending uncertainty that has dogged the solar industry for over a decade,” Phillips said.
While the government identified the clear role for “known technologies”, including offshore wind, solar and wave power in the context of renewables, it said other “nascent technologies, data, and innovative infrastructure projects” will be needed too and confirmed that planning decision makers should give “substantial weight” to “novel technologies or processes” that emerge during the lifetime of the policy statements where these are shown to have utility.
