Abstract
The new Energy System Model for Remote Communities (EnerSyM-RC) is implemented to quantify impacts fromadopting tidal stream power alongside solar PV, offshore wind and energy storage in the Isle of Wight energysystem. Based on scenarios with gross renewable energy generation matched to projected annual demand(equivalent to 136 MW mean power), installing 150 MW of solar PV, 150 MW of offshore wind, and 120 MWof tidal stream capacity enhances supply–demand balancing whilst also reducing the magnitude of maximumpower surplus, both by 25% relative to the best performing solar+wind system. Tidal stream adoption alsoreduces total land/sea space by 33%. The economic viability of tidal stream capacity adoption is heavilydependent on the price of reserve energy; when the reserve energy price exceeds the average 2022 forwarddelivery contracts price (250 £/MWh), adopting tidal stream capacity reduces the levelised cost of wholesystem energy relative to solar+wind systems. This tipping point, at which the whole-system levelised cost ofenergy is 92 £/MWh, occurs when the premium on tidal stream energy is outweighed by savings on reserveenergy. In general these system benefits arising from tidal stream adoption are consistent over a range ofdifferent demand profiles, and in cases where gross annual renewable supply is oversized relative to demand.
