Australia’s high potential for renewable energy generation and the high carbon content of Southeast Asian electricity create favourable conditions for a high voltage direct current (HVDC) power link connecting Australia and Southeast Asia. This interconnector would link predominantly large-scale solar farms located in northern Australia to Singapore given its central location within Southeast Asia, high reliance on fossil fuel for its power generation, high demand growth and limited renewable potential and land surface. This paper presents the expected annual reduction of greenhouse gas emissions that could be offered by an Australia–Singapore power link accounting for the entire life cycle including HVDC cable embodied carbon and emissions related to cable transport, installation, operations and decommissioning phases. A levelised cost of electricity has been calculated to assess the cost-attractiveness of projects of this nature compared to gas-fired plants accounting for capital costs, variable costs, fuel cost as well as the subsea cable cost. In a world of growing environmental concerns, the decreasing cost of solar photovoltaic combined with future stringent carbon policies will gradually result in a competitive levelised cost of electricity of large-scale solar projects coupled with an intercontinental power link in comparison to local gas-fired power generation.
