Environmental Impact Assessment Proposed Biomass Power Generation Plant at ‘Eua

This is an Environmental Impact Assessment report on Tonga Power Limited’s proposed biomass power generation plant at ‘Eua. This is off the eastern coast of Tongatapu Island, the capital island of the Kingdom of Tonga. The principal objective is to improve energy supply with an increasing use of renewable energy. Tonga’s Energy Road Map (TERM) provides a detailed pathway towards a low carbon, cost-effective, technically sound, equitable transformation of the entire energy sector in the Kingdom of Tonga. The Government of Tonga launched the plan in 2010, and now has a target of 100% renewable energy by 2020. The Kingdom is highly dependent on imported fuel to meet its energy requirements. In effect, the total fuel import accounts for about twenty percent of the total import value in 2011. Tonga Power Limited is the sole on-grid electricity production and distribution SOE in Tonga. The grid-supplied electricity accounts for about 98% of electricity and it is based on diesel generation. In 2013, TPL used 12,941,465 litres of diesel for power generation, which cost around , 500,000. This is essentially a huge cost for a small island state such as Tonga. However, under the current electricity regulatory structure the cost of fuel is essentially passed through to electricity consumers. In effect, the electricity consumers are fully exposed to oil price rises and fluctuations. TPL, within the framework of TERM 2010-2020, is proposing to establish a biomass plant in ‘Eua. This project will be another step forward in addressing the energy issues in Tonga and achieving the TERM 100% renewable target.
