TONGA NATIONAL ENERGY POLICY • VISION • Energy that is available, affordable, and sustainable for social and economic development for the people of Tonga. Tonga face a unique and challenging situation with respect to energy and sustainable development: • Demographics vary slightly between districts, but often experience small feature and isolated population centres. • Markets size is small and difficult to serve plus the limited significant economies of scale. • 10% of the total population experience limited access to electricity (Tonga Population Census, 1996). • Tonga contain a wide range of ecosystems, predominantly influenced by marine systems that make infrastructure development difficult and environmental impacts. • Unfortunately, Tonga does not have indigenous petroleum resources, but majority power of the Kingdom is operate from diesel.
PRESENT SITUATION OF RENEWABLE ENERGY IN TONGA • BIOMASS is of course the most wanted utilize primary RE source in the Kingdom • More than half of the Island population have access to electricity by using PV technology • Present PV Programme -There is a need to rehabilitate most of PV system in the outer island, both the institutional and technical -The latest PV programme which was funded by SPC seems to be very cost effective and could be a model for the future. • Problem Uncounted • -Recourses assessment is needed to be enhance.(Testing and Monitoring of wind system should be continue and with in different locations) • -Lack of technical knowledge among private sector as well as central public. • -Need private sectors participation interest (available of local PV participant) • -Regular training needs in really important to ensure feature success of RE projects. • IT’S A SMALL NUMBER OF PRIMARY ELECTRICITY FROM SOLAR ENERGY COMPARED TO THAT GENERATED FROM DIESEL

WIND ENERGY THE RESULTS OF WIND CONDITION ANALYSIS AT THESE TWO SITES ARE SHOWN BELOW
Recommendation • After this Feasibility study of wind power plant we learned that the break-even point is achieved when a Win Turbine Generator system(WTGS) receive wind of 6m/s at the height of 20m on the annual average. • Since either location investigated is far from meeting this criterion,it is impossible to construct a wind plant if the wind ever seek to gain profit. • As the turbulence intensity at either point exceeds 20%,WTGS would expect to suffer an rapid failure frequency and a reduction of services life. • Particularly at Anokula,the average turbulence intensity is extremely high about 30% and there are no general-use wind power generators that can sustain such turbulence intensity .Therefore,it is technically impossible to install WTGS at this location.
