Financing for 45-MW Kumbih 3 hydro project in Indonesia moves forward

Indonesian state-owned utility PT PLN Persero (PLN) and German development bank Kreditanstalt fà¼r Wiederaufbau (KfW) have signed a US$99.9 million agreement for the construction of the 45-MW Kumbih 3 hydropower project.

PLN said it will fund $18.2 million for the project, which it estimates will cost about $118.1 million.

The run-of-river plant will be located on Sumatra Island, Indonesia, at Kumbih River bordering the towns of Sidikalang Dairi, North Sumatra, and Subulussalam, Aceh. According to PLN, construction on the project is expected to begin in 2019 with a planned completion date sometime in 2023.

During the signing ceremony on Dec. 15 at PLN headquarters in Jakarta with PLN Corporate Planning Director Syovfi Felienty Roekman and KfW Senior Project Manager Jens Wirth, Roekman commented on the significance of the loan.

“This loan is a direct loan without government guarantees,” Roekman said. “This is interesting because funding agencies from European countries such as KfW support projects from renewable energy like this, from feasibility studies to funding.”

Roekman also said Kumbih 3, once completed, will help meet increasing power needs in Northern Sumatra and lower the country’s carbon footprint.

“It also lowers the cost of production on the use of fossil fuels both during baseload and peak load times,” she said. “And most importantly, add the portion of renewable energy in the national energy mix target.”

Wirth said the loan is important support for PLN that will help the utility increase electricity generated from renewable energy in Indonesia.

“We hope the implementation of the project can be run quickly so that it can be directly benefited by the community,” Wirth said.

PLN generates the majority of the Indonesia’s electricity, but earlier this year, the country’s first ocean energy independent power producer, SBS Energi Kelautan (SBSEK), joined the energy mix.

In October, reported SBSEK announced it completed final investment decision with SBS International Ltd. to move forward with the 12 MW, Phase I of the 150-MW Nautilus marine energy project in Lombok, Indonesia.

In October 2015, PLN selected an international consortium to build the 1,040-MW Upper Cisokan pumped-storage hydropower plant in Indonesia’s West Java province.

The consortium includes South Korea’s Daelim Industrial Co., Italian construction firm Astaldi SpA and Indonesia’s Wijaya Karya. In June 2015, PLN invited pre-qualification to supply hydraulic metal works for construction of the project.

PLN pre-qualified firms to construct upper and lower dams, waterways, powerhouse, and Upper Cisokan’s switchyard in 2013. Financing for the project is coming in large part from the World Bank, which approved a $640 million loan in 2011 to assist with project development.
