Request for Information (RFI) – Nevis Geothermal Energy Project

Nevis Electricity Company Limited (NEVLEC) is seeking to identify prospective bidders for a geothermal drilling campaign in Nevis Island, part of the Federation of St Kitts and Nevis in the Caribbean, by way of this Request for Information (RFI). NEVLEC is the sole provider of electricity on the island of Nevis and is fully owned by the Nevis Island Administration (NIA).

Technical support for the project is being financed by the Caribbean Development Bank (CDB) and the Inter-American Development Bank (IDB). It is intended that financing for the implementation of the project will be provided under the Sustainable Energy Facility (SEF) Programme of the CDB’s GeoSmart Initiative with resources from the CDB and the IDB.

The purpose of this RFI is to identify interested bidders, and to assist in developing the tendering strategy for the supply of the Services, as described in the Packages 1 through 4 below, to achieve a rapid and successful tendering process. We would like to get an indication of interest from prospective bidders for this project. Your response to this RFI does not require you to commit to bidding on the tender when released.

This is not a prequalification or shortlisting exercise, and the eventual procurement process shall be an open, competitive process, which will be open to all eligible bidders. Procurement shall be undertaken in accordance with the Procurement Policy for Projects Financed by CDB and the Procurement Procedures for Projects Financed by CDB1. The responses to this RFI will also inform decisions regarding country eligibility of prospective bidders.

The competitive tendering process is scheduled to start on October 3, 2022, with the release of tender documents, and conclude by the second week of December 2022, with the selection of the contractor(s). The drilling of the first well is anticipated to commence June 2023.

The Phase 1 (10 MWe) drilling campaign will include drilling five (5) geothermal wells (1 vertical and 4 directional) to approximately 4,500 — 5,000 feet measured depth (equivalent to 4,000 — 4,500 feet vertical depth), with a 13-3/8” OD production casing and 9-5/8” OD perforated liner in the 12-1/4” production sections. Indicative designs for the wells are shown in the Appendix.

The highest formation temperature is estimated to be 290°C. It is envisioned that the project will be drilled by a rotary drilling rig. The 13-3/8” OD production casing is programmed to be run and set at 2,500 feet vertical depth (2,800 feet measured depth). All casing strings will be cemented back to surface.

Preliminary calculations indicate that a rig with minimum pullback of 300,000 lbs. and minimum drawworks of 550 horsepower (hp) would be required. The first phase wells will be drilled on two pads (3 wells on one pad and 2 wells on the other pad), approximately 500 m apart, as the crow flies. Well pad sizes are expected to be in the order of 90 m x 60 m.

A second phase (Phase 2) project (expansion to 30 MWe) is anticipated to require four (4) additional wells, planned to be spudded shortly after Phase 1, depending on the drilling and well test results of the Phase-1 wells.
