Nevis Geothermal Wells Drilling Project

The Nevis Electricity Company Limited (NEVLEC), in conjunction with the Nevis Island Administration (NIA), is planning to develop a 10MWs of geothermal energy for Nevis. The Project is being considered to be partially financed by the Caribbean Development Bank (CDB) through the Sustainable Energy Facility for the Eastern Caribbean Global Credit Loan of the Inter-American Development Bank (IDB). As such, the Project must adhere to national guidelines as well as the International Finance Corporation’s (IFC) Performance Standards (PS) on Environmental and Social Sustainability (2012) and applicable IFC Environmental, Health, and Safety (EHS) Guidelines, as well as to the IDB Environmental and Social Operational Policies. ERM, an international sustainability consulting firm, was retained to prepare a Preliminary Supplemental Environmental and Social Impact Assessment (ESIA) of the Nevis Geothermal Project, to complement a 2017 EIA and 2020 Addendum carried out by Point Impact Analysis. This Supplemental ESIA addresses the drilling of 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. Of the total number of wells, three will be production and two injection wells. The three production wells will be located on the main Hamilton Estates property while the injectors will be completed downslope from the plant, at the 1.2-acre Hamilton Stable parcel. The drilling project is a key initial phase of the overall plan to develop a geothermal energy project in Nevis.
