"The results indicate the presence of a considerable (4 – 8km2), high-temperature resource (200°C to 290°C) located north of Mount Saint Catherine."

The Ministry of Finance and Energy will on Thursday, July 30th, 2015, present the findings from the Geology, Geophysics and Geochemistry surveys (3Gs surveys) which were undertaken with the assistance of the Government of New Zealand, earlier this year. The findings will be presented to potential development partners; local stakeholders and the media between 9:30am and 4:00pm at the Ministry’s Conference Room.

A Geothermal Reconnaissance Study was conducted in Grenada, in 1981, with the assistance of the Latin American Energy organization (OLADE). This concluded that the most favourable area for geothermal investigation was the Mt. Saint Catherine area and recommended that a subsequent Feasibility Study be undertaken there.

Geothermal Pre-feasibility Studies were conducted between August 1992 and March 1993, by the Geothermal Consultant, Mr. Gerald Huttrer, of the Geothermal Management Co., Inc., to determine the Potential for Geothermal Development.

The geological and hydro-geochemical studies identified six (6) sites with surface manifestations in central and northern Grenada, and apparently commercial temperatures of 320-420 C. An additional study of the three (3) most prospective sites was recommended on the basis of accessibility and apparent resource quality.

In September 2014 the Governments of Grenada and New Zealand through their Ministries of Foreign Affairs, signed a Geothermal Support Partnership Framework with the aim to provide technical assistance in the form of Geoscience studies in order to help define the prospects for advancing geothermal development in Grenada.

Through this Agreement, the Government of New Zealand (New Zealand Aid Programme) provided funding to cover a Technical Assistance contract to undertake the studies.

A New Zealand company, Jacobs New Zealand Ltd. was contracted by the Government of New Zealand to execute the Terms of Reference of the contract.  Mr. Alastair Brooks, the Caribbean Geothermal Advisor and Jacobs’ representative, is the head of this initiative and provided overall direction for the studies.

The Grenada survey comprised of three main focus areas namely: Geological Survey; Geochemical Survey; and Geophysical Survey. The investigation was completed to a high standard, typical of the international geothermal industry practice for a pre-drilling surface exploration programme.

The results indicate the presence of a considerable (4 – 8km2), high-temperature resource (200°C to 290°C) located north of Mount Saint Catherine.

Thursday’s presentations will be done by Mr. Brooks with support from the Energy Division of the Ministry of Finance and Energy which coordinates geothermal development. The presentations will be done as follows:

·         Eternal development  partners – 9:30 am

·         Local stakeholders – 1:30 pm

·         Media – 3:00 pm

Thursday’s discussions will also set out a road map for the development of Grenada’s geothermal potential.
