Why are electricians licensed in Tonga?

Electricity has the potential to kill if used improperly or by unskilled labour. That is why electricians are licensed in Tonga by the Commission who ensure that they are permitted to practice as such only if have the required theoretical and practical knowledge of their subject and adequate hands on experience of electrical works.

What is Tonga's electrical safety oversight?

Another important aspect of Tonga’s electrical safety oversight is the Electrical Permits regime. The policy behind the electrical permit regime which has been in vogue in the Kingdom of Tonga since 1985, is Public Safety, in particular the prevention of death or injury to persons, or danger to property from electrical hazards.

Can energy storage technologies improve fossil thermal plant economics?

The research involves the review, scoping, and preliminary assessment of energy storage technologies that could complement the operational characteristics and parameters to improve fossil thermal plant economics, reduce cycling, and minimize overall system costs.

Are there cost comparison sources for energy storage technologies?

There exist a number of cost comparison sources for energy storage technologies For example, work performed for Pacific Northwest National Laboratory provides cost and performance characteristics for several different battery energy storage (BES) technologies (Mongird et al. 2019).

How can a thermal plant improve efficiency?

Potential increase in efficiency in controls and thermal storage integration. Opportunities to integrate into thermal plants by saving the cost of heat storage and using excess cold to increase thermal plant efficiency during peak power operation (increasing condenser efficiency).

How can we improve energy storage based on grid and integration benefits?

Improve techno-economic modeling tools to better account for the different fossil thermal power plants and their characteristics and expand their storage technology representations to allow for quantitatively evaluating the benefits of energy storage based on grid and integration benefits.
