Proposed Development Objective(s)
Original PDO
The project development objective (PDO) is to increase the share of renewable energy through
hydropower in Solomon Islands.
Current PDO
The project development objective (PDO) is to increase the share of renewable energy through
hydropower in Solomon Islands.
Progress will be measured against the following PDO level results indicators, as applicable:
a. Share of renewable energy in the generation mix (%);
b. Generation capacity of hydropower constructed under the Project (MW); and
c. Electricity generated by the Project (GWh).
D. Project Description
The TRHDP will consist of four components: (i) hydropower facility (HPF); (ii) access road; (iii)
transmission line; and (iv) technical assistance.
Component 1: Tina River Hydropower Facility (TRHPF) (Estimated cost: US$187.059 million). Under a
34-year PPA (including 4-year construction period), the Project Company, Tina Hydropower Limited (THL)
will develop, finance, construct and operate the HPF with an installed capacity of 15 MW located on the
Tina River, 20 km southeast of Honiara, and will comprise:
a. A roller-compacted-concrete (RCC) dam 72 m high (from foundation) located in a narrow gorge
on the Tina River;
b. A waterway including a 3.3 km headrace tunnel in 3.3 m diameter, surge shaft and a surface-type
steel penstock in 3.0 m diameter to convey water from the dam to the power station;
c. A powerhouse 5.7 km downstream of the dam site that will house three 5 MW Francis turbines
and an extra bay for future installation of a fourth 5 MW turbine.
Component 2: Access Road (Estimated cost: US$25 million). The access road to facilitate HPF
construction and operations includes two lots: Lot 1 involving the upgrade of the existing 13.2 km road
from Black Post Junction to Managikiki Village; and Lot 2 involving a 5.5 km “greenfield” road through
steep heavily forested terrain from Managikiki Village to the dam and power station sites. Upon
commissioning of the HPF, Lot 1 will become the responsibility of SIG and Lot 2 will remain the
responsibility of the Project Company (PC) for the duration of the PPA, after which it will hand over to
SIG together with the HPF.
Component 3: Transmission Lines (Estimated cost: US$22.82 million). Generated power from the HPF
will be evacuated to HES through two parallel single-circuit 66 kilovolt (kV) transmission lines of 21.6 km
to the existing Lungga Diesel Power Station. The cost of this component includes the upgrading of Lungga
Power Station since the highest system voltage at present is 33 kV.
Component 4: Technical Assistance (Estimated cost: US$7 million). This technical assistance (TA)
supportsthe operation of the TRHDP Project Office (PO) under MMERE to finance consultants to monitor
overall project implementation, provide awareness building and training for various stakeholders,
monitor and support social and environmental safeguard arrangements and the Gender Action Plan
(GAP), maintain a Dam Safety Advisory Panel (DSAP) and an independent social and environmental
monitoring agent, liaise with various government counterparts and other stakeholders, support
implementation arrangements agreed under the land acquisition process, support communities in
utilizing their share of project benefits for community development, and to report to the Bank and other
financiers on project performance and achievement of objectives. A non-governmental organization
(NGO) will also be engaged to work with landowning tribes in the upper catchment to support the first
stages of establishing a protected area, up to the point of preparing a Protected Area Management Plan
and Budget, if community members are interested and committed to doing so. |
