Telecommunications Consultants India (TCIL) has invited expressions of interest (EoI) to select a consortium partner for implementing a 120 MW Solar project at Wobthang in Bhutan.

The bids must be submitted by January 30, 2026. Bids will be opened on the same day.

Bidders must furnish an earnest money deposit of ₹10 million (~$111,000) and a tender fee of ₹11,800 (~$131). The successful bidder must submit a performance security of 10% of the contract value.

The scope of work includes the design, supply, installation, testing, engineering, procurement, and construction of the solar project, with operations and maintenance requirements.

Bidders must have completed similar solar projects with a participation value exceeding $49 million within the last five years. The bidders must also have experience in the design, supply, installation, testing, and commissioning of solar PV plants, with a minimum cumulative experience of 90 MW covering solar modules, inverters, mounting structures, and supervisory control and data acquisition or grid connectivity systems.

Bidders must have an average annual turnover of at least $15.5 million over the last five financial years, a positive net worth during the same period, profit before tax in at least two of the last three financial years, and available financial resources of not less than $3 million.

Consortium participation is permitted with a maximum of 2 members, with the lead partner required to meet the full experience criteria and to account for at least 25% of the turnover requirement.

Liquidated damages for delays are capped at 12% of the contract value, with performance-related liquidated damages included within the same provisions.

The Asian Development Bank is evaluating lending for the 120 MW Wobthang solar project, along with a 40 MW solar project in Bumthang and a 170 MW solar project in Lhuntse. The estimated cost of the 120 MW Wobthang solar project is $62 million.

In February 2025, TCIL invited expressions of interest to select a consortium partner to implement a 120 MW ground-mounted solar project. The project will be developed in Jamjee, Mewang Gewog, Thimphu, Bhutan, as part of Druk Green Power Corporation’s tender.

The project’s construction has been awarded to the HILD-Rigsar consortium under an engineering, procurement, and construction contract signed on July 15, 2025. Scheduled for completion within 18 months, the project is expected to generate approximately 197 GWh of clean electricity annually.

The project is estimated to cost Nu. 4,703 million (~$56 million). The European Investment Bank (EIB) will finance 50% through a concessional loan under the Hydro and Solar Energy Facility signed in April 2024, while Druk Green Power Corporation will fund the remaining 50% from its own resources.
