“…GB's 2030 energy system will include heavy usage of renewables for power production, no power production from unabated coal-fired plants, increased gas-fired power production (with and without carbon capturing and storage, CCS) to improve the energy system's flexibility, the use of electricity for heating, and enhanced power trading (imports/exports) to/from GB. The heat rate (efficiency), summer and winter availabilities, and ramping (up and down) rates of the electricity generation technologies were taken from [17,22].…”

“…It is assumed that the total electricity interconnector capacity between GB and its neighbors will reach 17.7 GW, of which the capacity of the interconnector with France is 5 GW. The France-GB interconnector was considered in a way to allow electricity to flow in and out of GB until 2030, and the interconnectors between GB and other states were assumed to import electricity to GB at 20, 40, 80, and £100/MWh [22]. Therefore, the latter will transmit electricity to GB when the half-hourly demand cannot be met by GB's available generators and electricity imports from France.…”

“…(1) The heating technologies considered were combined heat and power (CHP) installations, gas and boiler, direct electric heaters, ground source heat pumps (GSHP), and air source heat pumps (ASHP). The contributions of heating technologies in heat supply were taken from [17,22] and correlated with the daily heat demand by Equation (2). It is expected that nearly 42% of GB's total heat demand by 2030 shall be provided via electricity.…”

This paper investigates the future role of cross-border electricity flow between Great Britain (GB) and its neighbors until 2030, considering high deployment of renewable energy sources (e.g., wind, solar, and biomass), enhanced interconnection capacity, and a partly electrified heating sector. It was assumed that two cross-border interconnectors links will connect GB’s power system to its neighbors: (1) a one-way interconnector (IC1) that imports electricity to GB, and (2) a two-way one (IC2) between France and GB. The IC2 was allowed to transfer electricity from a cheaper power system to a more expensive one. The results show that at a fixed CO2 price, a change in power imported via IC1 will affect the power dispatch of the CO2 emitting power plants and biomass-fired power plants, and electricity trade via IC1 and IC2. At IC1 importing of £60/MWh, by raising the CO2 price from 60 to £70/ton, the share of CCGT power plants will reduce by 75%, and the power imported via IC1 link will face 19-times growth. With a constant IC1 import price, raising the CO2 tax will reduce the total quantity of electricity being exported to France via IC2. Moreover, increasing the CO2 tax will increase the emissions cost of gas and coal-fired generators, and the power required to meet the demand will be imported via IC1. With the IC1 electricity price set to £20/MWh and the CO2 tax set to £50/ton, there may be 595 periods out of 17,520 in which GB will be used as an electricity trade corridor. GB’s total CO2 emissions should drop as the CO2 tax increases.
