Design, Construction, Installation, Integration Solar PV and battery power systems

The Asian Development Bank (ADB) was conceived in the early 1960s as a financial institution that would be Asian in character and foster economic growth and cooperation in one of the poorest regions in the world.

ADB assists its members, and partners, by providing loans, technical assistance, grants, and equity investments to promote social and economic development.

The Tonga Power Limited and Ministry of Meteorology, Energy, Information, Disaster Management, Environment, Climate Change and Communications has applied for financing from the ADB, and Green Climate Fund (GCF) toward the cost of the Tonga Renewable Energy Project. Part of this financing will be used for payments under the contract named above. Procurement rules and procedures of ADB will govern the bidding process. Bidding is open to all Bidders without nationality restriction.

The Ministry of Meteorology, Energy, Information, Disaster Management, Environment, Climate Change and Communications (“the Employers”) invite sealed bids from eligible Bidders for the design, construction, installation, integration Solar PV and battery power systems (“the Facilities”) of the Vava’u outer islands of Tonga as shown below:

To supply four (4) independent power systems to the Vava’u Island Group of Falevai, Hunga, Ofu and Otea to create independent minigrids.

Each power system shall consist of a village level solar PV array and battery energy storage system (BESS), and a distribution system and customer connections. There is no current centralized power supply on these islands. The power systems are required provide power 24 hour per day 7 day per week meeting the estimated island demand, which are estimated as being:

(i)  Falevai (27kW solar, 11kW/305kWh BESS)
(ii)  Hunga (72kW solar, 30kW/825kWh BESS)
(iii)  Ofu (39kW solar, 17kW/450kWh BESS)
(iv)  Otea (30kW solar, 13kW/340kWh BESS)
