Tonga’s energy data collection and the availability of energy data and information fairs relatively well on the supply side of the power sector. The challenges lie with non-power data, particularly on the demand side – final consumption by sector for both power and non-power (particularly oil products) sectors.
Currently, there is no storage of energy data in Tonga, which contains both supply and demand side data except a draft database prepared last year by PCREEE and DOE for trial – although many missing parts of the table need to be filled.
The responsibility of data collection and its categorization is not yet clear in Tonga – although certainly of national interest. Considering that DOE, MEIDECC is responsible for energy policy, DOE should be the center of the energy data and its collection. Data related to electricity is prepared and stored in TPL.
The national needs of energy data in Tonga are particularly strong for concerns on 1) energy security, 2) future energy planning, and 3) trade balance from energy imports/exports. To analyze these concerns, capturing the national energy flow and constructing the energy balance are critical first steps.
Tonga 2 is a 3.3-hour system with 7.2MW/23.9MWh of energy, designed primarily for load shifting. They have already allowed Tonga to double its renewable energy capacity with the recent addition of 6MW in solar PV power, bringing the country’s renewable mix to around 20%.
There are other important indicators missing for Tonga, such as ‘primary energy supply’ and ‘final energy consumption’. However, these can be easily derived after the creation of an energy balance table. Data related to energy is in the menu “Energy and Natural Resources”. The first two items; are considered highly important.
