The Nevis Electricity Company Limited (NEVLEC) wishes to advise customers and the general public that Genset No. 8 at the Prospect Power Station will be taken out of service from Sunday, 9th August 2026, through Wednesday, 2nd September 2026, to facilitate its scheduled 48,000-hour major overhaul.

The overhaul forms part of NEVLEC’s planned maintenance programme and is necessary to ensure the continued reliability, efficiency and safe operation of the generating unit.

The works will be undertaken jointly by NEVLEC’s technical team and specialist technicians from Wärtsilä, who are on Nevis to support the major overhaul.

An important component of the exercise will also be capacity building and knowledge transfer. NEVLEC’s technical personnel will work closely alongside the Wärtsilä specialists throughout the overhaul, providing valuable hands-on exposure to major maintenance procedures, inspections, component replacement, testing and other technical aspects of the generating unit. This will further strengthen the internal technical capacity of NEVLEC’s Generation Department.

During the overhaul period, NEVLEC will utilize its other available generating units and operational arrangements to maintain electricity supply. However, with Genset No. 8 unavailable, the electricity system will operate with reduced generation reserve capacity.

While every effort will be made to maintain a continuous and reliable electricity supply, customers are advised that should an unforeseen issue arise with another generating unit during the overhaul period, temporary interruptions or load management may become necessary.

NEVLEC’s technical team, working in collaboration with the Wärtsilä specialists, will make every effort to complete the overhaul within the scheduled timeframe. Following completion of the required works, the generating unit will undergo the necessary testing and commissioning procedures before being returned to service.

This major overhaul represents an important investment in the continued reliability of NEVLEC’s generation assets while simultaneously developing the skills and technical capabilities of the company’s employees.

NEVLEC appreciates the patience, understanding and cooperation of our customers and the general public as we undertake this important maintenance exercise.

Further updates will be provided should there be any significant changes to the scheduled works or electricity supply arrangements.
