GGA Conference - WFES Abu Dhabi - 18.01.2017
• The Gov. of the Federation of St Kitts & Nevis and Teranov entered into a Memorandum of Understanding and a Roadmap in sept 2015
• The MoU covers the geothermal development from A to Z: The exploration phase The development and construction phase The long term exploitation phase
• The Roadmap sets: The agenda & the objectives The partners’ contributions The legislative framework modifications (Dec 2015)
• Main partners’ engagements: Build broad support for the project as well as to manage public expectations Provide open and transparent communication at each phase of the project
Public Private Partnership
GGA Conference - WFES Abu Dhabi - 18.01.2017
• Previous Caribbean regional preliminary studies, including GeothermicaItaliana in 1992, have identified two main areas of interest on St Kitts, which remained unexplored until now due to the lack of surface manifestation:
• North-Western area was favored considering:
Existing data/analysis Surface manifestations Land use

• Resource estimate using the stored heat method following the Australian code net of power plant losses (-10%) but without pumping losses
• Probabilistic estimation: Resource estimation between 18 to 36 MWe P50 estimation of the plant capacity = 27 MWe P90 = 18 MWe meaning that according to our analysis and based on available surface data, 90% of chance to have more than 18 Mwe
• Complete 3G exploration works are currently under independant Peer Review process by GRG (USA).
