2.6 continued Renewables Figure 2.6.6: Marine contracted Vs scenarios GW 4 3 2 1 0 2.6.3 Marine Figure 2.6.6 shows the current contracted position for marine (wave and tidal generation) against the requirement for marine generation under each of the three scenarios over the period to 2032. In the Gone Green scenario the level of marine generation capacity required in 2020, if the scenario is to be met, is 20 MW. The current level of marine generation capacity that is either existing or under construction is 7 MW, therefore leaving a total of 13 MW (of the 2 GW that is contracted with a signed connection agreement and completion date before 2020) to be connected to the transmission system by this Page 40 2012 2013 2014 Marine Existing 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 Marine Under Construction Marine Awaiting Consent Marine Scoping 2025 2026 2027 2028 2029 2030 point. By the end of the period the Gone Green scenario shows a marine generating capacity of around 1.3 GW. In Slow Progression, marine is assumed to develop very slowly due to high costs, with minimal deployment by 2030. 2031 Marine Consented In Accelerated Growth, there is a stronger build up of marine capacity, mainly post 2030. SP GG Apart from the 7 MW of existing or under construction capacity all marine generation is currently in the scoping phase. 2032 AG
Figure 2.6.7: Biomass contracted Vs scenarios GW 4 3 2 1 0 2012 2.6.4 Biomass 2013 2014 Biomass Existing 2015 2016 2017 2018 2019 2020 Figure 2.6.7 shows the current contracted position for biomass capacity generation against the requirement for biomass generation under each of the three scenarios over the period to 2032. The information in this chart is distorted slightly by the assumption in the scenarios that a significant proportion of any future biomass developments may be from the conversion of existing coal-fired capacity into a dedicated biomass generation. Assumptions around these conversions may not be reflected in the contracted background as the stations identified will currently be classified as fossil fuel stations. Therefore, the graph shows under the contracted background there is currently only just enough generation with a signed connection agreement to meet the level of biomass generation for the Gone Green scenario and not enough to meet Accelerated Growth. 2021 2022 2023 Electricity Ten Year Statement November 2012 2024 Biomass Under Construction Biomass Awaiting Consent Biomass Scoping 2025 2026 2027 2028 2029 2030 2031 Biomass Consented Under the Gone Green scenario the level of biomass generation capacity required in 2020, if the scenario is to be met, is approximately 2 GW. The current level of biomass generation capacity that is either existing or under construction is 1 GW therefore leaving a total of 1 GW (all of which is contracted with 0.7 GW having obtained consents) to be connected to the transmission system by this point. By the end of the period the Gone Green scenario shows a biomass generating capacity of approximately 2.4 GW. In the Slow Progression scenario there is a limited level of biomass growth, with no further conversions apart from those already operational or currently being converted, and an assumption that these plants will close in 2016. In Accelerated Growth there is strong growth in biomass with a total capacity of around 3.5 GW reached of which 1.5 GW is conversions. SP GG 2032 AG Page 41
