97% of Bermuda’s energy is supplied by Belco’s diesel-fuelled generators located behind Hamilton. 3% of our electricity is supplied by burning municipal waste at Tyne’s Bay, and less than 1% comes from solar electricity generated from solar panels on residential roofs.

Your Electricity Bill:

The amount we pay for electricity is high in Bermuda relative to other countries. Our electricity charge is made up of 3 main elements:

  1. Your Billing Charges are calculated based on your electricity consumption this month, using a rate structure with 3 tiers. The rate per kWh rises the more units you use. That means that when you reduce your consumption, you’ll be saving the most expensive units used first.

  2. Your Fuel Adjustment is also calculated based on your electricity consumption this month. It is a fixed rate per kWh set to offset the current market price for oil, plus the cost of refining, shipping it here to Bermuda, customs duty and pumping.

  3. Your Facilities Charge is a fixed monthly charge for delivering electricity and support services to you. The applicable charge is determined by something called your Annual Rolling Daily Average, which is an average of your daily usage over the past 12 months. Your Annual Rolling Daily Average is now shown, in kWhs, on your bill.

    There are five Facilities Charge charge rates (last updated on June 1,2016); $20, $30, $39.95, $62.50 or $95 per month. Which rate you pay depends on how heavy a consumer you are. If you’re a light energy user using an average of 10 kWh or less per day, your Facilities Charge is $20 each month. At the high end, if you’re using an average of 50 kWh or more per day, your Facilities Charge is $95 each month.


Electricity Conservation:

There are two reasons to conserve electricity: firstly, it will cost us less, but also electricity generation has a significant impact on the environment.  In fact The Economist in 1991 claimed that “using energy in today’s ways leads to more environmental damage than any other peaceful human activity.” Energy generation is a significant source of greenhouse gas emissions which contribute to global climate change, the extraction of fossil fuels also caused pollution and environmental damage at the site they are drilled or mined, and also in transporting them to Bermuda. In addition, all our diesel fuel is imported, which is a negative contribution to Bermuda’s balance of payments



Ideas for Conserving Electricity:

  • Heating Ventilation and Air Conditioning (HVAC): Typically about 30% of your bill:

    • Use fans & cross breezes for ventilation  and only use AC  when other ventilation is inadequate.

    • Don’t cool or heat unoccupied rooms

    • Keep doors and windows closed when AC is on.

    • Clean filters

    • Use ceiling fans with AC to increase your comfort range

    • Ceiling fans should be set counter-clockwise in summer and clock-wise in winter.

  • Water Heating: typically about 17% of your bill

    • Not So Hot! Reduce thermostats to no higher than 120°F. No electrician required.

    • Add a timer to your traditional electrical water heaters.

    • Unplug when not in use.

  • Lighting: typically about 11% of your bill

    • Replace with compact fluorescent bulbs (reduce energy use by 75%) or LED bulbs (reduce energy use by 90%)


Two case studies for energy conservation in Bermuda:

Residential Efficiency Opportunity

A Bermuda resident wanted to reduce their energy consumption in their four bedroom, average-sized house, without significant investment. Efficiency measures included:

1.      Switching to Energy Star rated appliances as old appliances reached the end of their useful life

2.      Switching out incandescent bulbs for CFLs or LED bulbs (approximately $600 investment)

3.      Adding timers to water and closet heaters and turning the thermostat down on the hot water heater ($700 investment, including installation by an electrician)

4.      Adding a smart switch to media electronics so that they could all be completely turned off with the TV when not in use

The resident made the changes starting in mid-2013 and has seen a 30% reduction in electricity use – see red line compared with earlier years. (The sharp dip in November 2014 is due to extended outages as a result of Hurricanes Fay and Gonzalo)

Cumberland House Retrofit Program:

Cumberland House, built in 1988 is a 94,000 sq ft office building in Bermuda CBD, with 6 tenants. It was retrofitted for energy efficiency in 2011/12. An energy audit recommended:

  1. Switching out the lights from incandescent and fluorescent to LED

  2. The installation of a metering system to allowed monitoring and management of energy consumption in 72 zones

  3. The installation of an updated, remotely accessible Energy Management System

The program cost $600,000 and took 15 months; consumption of electricity was nearly halved, and the payback on the investment was 33 months.
