Generation in BermudaBELCO's Central Plant is located¬†on 23 acres of property in Pembroke.¬† It is divided into the the East and West Power Stations, containing a total of¬†21 diesel and gas turbine engines. All of these units generate power at a frequency of 60Hz. The derated maximum amount of power BELCO's generation plant produces is 167 MW of electricity.
The diesel engines carry the basic load of power used on a daily basis. They are slower to start up than the gas turbine engines but are more efficient to operate. In contrast, the gas turbine engines can be used almost immediately upon being started up.
The demand for electricity is always greater in the summer than in the winter. This is because the people of Bermuda begin using air conditioners as the weather gets hotter. To date, the highest summer peak demand of 122.8 MW was recorded in¬†August 2010.
Fuel:The fuel used for the engines at BELCO varies, depending on which engines are in operation. Heavy fuel oil is used to operate the four newest diesel engines and light diesel fuel is used to operate the gas turbine engines.
BELCO imports all of its fuel. The fuel is pumped through a nine-mile pipeline from Esso's storage tanks to three bunker tanks on the BELCO property. In 2009, BELCO used approximately one million barrels of fuel to produce electricity for Bermuda.
