Electricity Generation


Connect Saint Helena Ltd generates electricity in 3 ways:
  • Diesel Powered Generators at the Power Station in Ruperts
  • Wind
  • Solar
Electricity from Diesel
At present approximately 75% of the islands electricity is generated from burning fossil fuel (diesel).  We have 6 generators which have a total capacity of 7,600kW.

Connect Saint Helena Ltd is committed to reducing reliance on diesel power generation by harnessing renewable energy sources. Renewable energy is cheaper to produce and does not harm the environment.

Electricity from Wind
We currently have 12 wind driven turbines located at Deadwood Plain. These turbines provide in excess of 20% of the islands electricity. During peak windy months, this can be as high as 30%.

Electricity from Sun
We have 4 small roof mounted photovoltaic (solar) power plants at the:
  - Power Station
  - Carnarvon Court Offices
  - Seales Corner Offices
  - Community Care Complex
These were installed as pilot schemes. They have proven to require very little maintenance and provide energy during the daytime which is when our demand is highest.

The success of the pilot schemes mean that we are actively pursuing schemes which will generate more energy from solar sources. In Half Tree Hollow Connect have developed and installed a 500kWp solar farm which  further increases provision from renewable energy sources.  These solar installations generate approximately 5% of the island's electricity.

The below graph shows the amount of electricity (kWh) generated by means of diesel, wind and solar since Connect's start in 2013.

Maximising Efficiency
​We closely monitor both the demand for electricity and the availability of power from renewable sources. This enables us to switch between the various sources for maximum efficiency. So, for example, on a windy day we may be able to switch off a generator and therefore use less diesel.


St Helena’s use of renewable energy sources is already significantly higher than in the UK and most of the rest of Europe.

We have made some amazing efficiency improvements.  Primarily these are as a result of the renewable energy contribution.  The more efficient generators installed in 2012 also contribute.  By any standard these are world class improvements that help keep generation costs down and also reduce damage to the environment caused by burning fossil fuels.

The Team's commitment is:
  • Ensure that generation capacity is in excess of customer demand
  • Maximise generation from renewable sources
  • To generate electricity at the best efficiency reducing cost wherever possible.
