In the Caribbean Island Montserrat already three exploration wells have been drilled in the year 2014 and 2016, with the support of DFID in UK. The result was encouraging showing heat of over 200° Celsius at at 1800 meter deep, but the permeability could have been better. Following a flow test the estimated output was less than 3 MWe, which was considered below expectation.

It was Iceland Drilling Company who successfully drilled those wells under a integrated contract. That approach requires the drilling contractor to supply all related drilling services, and in addition to supply all material needed, such as casing, drilling fluid and cement.

Further development towards building a power plant has been delayed
