Submission on behalf of the Faversham Society on the Need for CHSP - Deadline 3\
3.The UK solar market
Many markets globally have ended direct subsidies in favour of unsubsidised markets or auction processes where governments procure electricity from the least expensive plants available. This has all driven the requirement for PV to become competitive with other forms of generation. The supply chain has responded in improving production efficiencies of PV systems and their constituent parts, resulting in reductions in capex of PV plants globally.
Given the costs reductions currently in train, the initial costs of installing solar PV in the UK are currently estimated to be c. £400-500k/MW. Given these prices, UK solar is now on the verge of cost competitiveness, and as these cost reductions continue, it is widely considered that it will be competitive with other generation within months.
The UK solar industry is responding and localised solar PV development is increasing with many development and construction cycles which are much shorter than those for other forms of renewable generation. This is especially so for those under the less than 50MW devolved planning process undertaken for all solar PV generation to date. CHSP is the first and only PV plant to be going through the NSIP process.
Submissions in local planning portals provide an accurate estimate of the solar PV projects that are currently in development. These can be considered in conjunction with those in pre-application and consultation phases to give a reliable indication of solar PV coming on stream over the period 2019-2022.
4. FES 2019 and Zero Carbon by 2050
As noted above, FES 2019 takes account of the new policy framework and target for zero carbon by 2050. FES 2019, Fig 5.4 indicates a 2050 solar capacity (demand) of c52GW of which only 42% is centralised. Moreover, FES 2019, Fig.3.2 on decentralisation is also of interest since it indicates that for the Community Renewables scenario, total centralised capacity stays fairly constant right up to 2050. This indicates that even in the zero-carbon scenario there is no role to be played for massive centralised installations such as CHSP. FES 2019 projections also detail and take account of significant energy demand reduction measures up to 2050.
5.Conclusion The chart below shows the total estimated new generating capacity outlined by National Grid in each of the National Grid deployment scenarios described above over the four-year period 2019 to 2022
As shown in Table 2 above the highest deployment projection for solar currently envisaged by National Grid (Community Renewables) is 4.1 GW from 2019 to 2022. Even without new additional solar PV, which will inevitably come on line in the coming years, the estimated capacity currently in planning (Table 3), excluding Cleve Hill is 4.3 GW which exceeds this projection. In addition the trend is away from centralised generating capacity such as Cleve Hill.
This indicates that by the planned completion date for CHSP there will already be sufficient solar PV capacity in the UK to meet our projected energy and decarbonisation needs.
This establishes conclusively that CHSP is not needed and will be redundant before it is completed.
