Renewable power generation is cost-effective

The cost of renewable power generation has decreased drastically over recent years, reaching levels lower than the fossil fuel-based power technologies.

Tonga is endowed with abundant renewable energy potential, with its solar potential estimated to be 767,297 MWh/year (NREL, 2010). With the cost of solar power generation reaching a level that is much lower than diesel power generation, Tonga may consider ramping up its solar power capacity towards 2030. LEAP’s least-cost optimisation approach has considered the cost of production from different power generation technologies and has suggested a quick ramping up of both renewable power capacity and power generation, reaching a 93 per cent renewable generation in 2021 and a 97 per cent in 2030. Nonetheless, this implies an early retirement of the existing diesel power capacity.

*this recommendation is applicable for all ambitious scenarios
