REPLACEMENT
GENERATION

We need to replace 50% of our generation capacity in order to ensure Bermuda maintains a reliable, safe and cost effective electricity supply into the future.

Why do we need
replacement generation?

  • A significant portion of the generation fleet is at the end of, or beyond, its useful service life.
  • Extending the service life of the older generators do not make financial sense; nor, in some cases, is it physically possible.
  • System reliability is deteriorating and there is a potential risk of catastrophic failure.
  • Replacing the aged generators is less costly than continuing to operate and maintain them.
  • 80 megawatts (MW) of the existing 161 MW of generation capacity is scheduled to be decommissioned by 2020 – This is approximately 50% of our current generating capacity.
  • After the decommissioning of the 80MW of power in 2020, there will be insufficient capacity on the Island to address the demand for electricity.
  • Without a new generation plant, BELCO cannot maintain a reliable, safe and cost effective electricity supply for Bermuda.

OUR SOLUTION:

Build a new, dual-fuel, high efficiency generation plant, with an estimated total project completion time of 21 months.

What are the details?

  • 80 MW (eight generators) will be retired by 2020.
  • A new power station would be built on BELCO’s existing Pembroke facility to house the replacement generators;
  • 60 MW of generating capacity would be constructed including four dual-fuel engines (56MW) and a heat recovery steam generator (4 MW) that would use steam from the operating dual-fuel engines to generate additional electricity;
  • Dual-fuel engines that will run primarily on natural gas, but will be capable of running on fuel oil would be used; this provides a redundancy for fuel supply and LNG is a cleaner and more efficient option.
  • One 4.5MW gas turbine unit would be installed to support the required back-up generation and generation needs for high demand periods; and
  • Suitable remaining generators would be converted to natural gas operation so they could continue to run reliably and be more environmentally friendly.

PROJECT BENEFITS:

  • Increased system reliability
  • More cost effective approach to generating electricity
  • Operations that are cleaner for the environment
  • Significant decrease in the vibration and noise level currently experienced by nearby residents

"With the replacement generation and transition to liquefied natural gas, we will save approximately $26 million each year."

Athanasius
DIRECTOR PROCUREMENT & LOGISTICS

"As power generation evolves, liquefied natural gas is used more. It is more efficient, safer for the environment and cost effective."

Corey
WASTE & WASTE WATER PROCESS CONTROLLER

"The older the generator, the harder it is to find the correct manufactured part. Sometimes we have to fabricate parts to make it work."

Casey
SPECIALIST ELECTRICAL FITTER

"The old power station has seen its time…the challenges that exist are real."

E. Symonds
ENGINE OPERATOR

"Working with the older generators is inefficient – they’re a challenge to work on every day and as they age, more problems occur."

Graham
SPECIALIST MECHANICAL FITTER

"Some days can be frustrating. We trouble shoot the same issues over and over."

Laureno
FOREMAN - PLANT OPERATIONS

"With the replacement generation, fuel emission levels will drop considerably. There will be a positive impact on the environment and for the population of Bermuda."

Russell
SENIOR PLANT ENGINEER

"Once we convert to liquefied natural gas, we will have a more stable electricity rate moving forward."
