Carbon Reporting

At Guernsey Electricity we are committed to reducing our carbon intensity for the benefit of the island. This means staying not only abreast of but ahead of international best practice for reporting.

As a signatory of the Kyoto Protocol - the UN Convention on Climate Change's framework for Greenhouse Gas (GHG) emissions mitigation, adaptation and finance - Guernsey has committed to tackling climate change and a ‘80% reduction of carbon emissions on 1990 levels by 2050’.

Guernsey Electricity is fully supportive of this target. As a business we have already taken steps to reduce our emissions by 66% on our 1990 levels. During our 2020 reporting period, 94%% of the energy supplied by Guernsey Electricity was low carbon, sourced from hydroelectric and other renewables through the cable link with France. We are also taking measures to further reduce our carbon emissions, including installing community scale solar panel arrays and phasing electric vehicles into our fleet. 

Our GHG emission data collection methodology, allows us to disclose all of our greenhouse gas emissions involved in the company’s activities directly under the control of Guernsey Electricity. Currently, supplier and contractor emissions are not included in our reporting.

The process also now enables us to break our carbon reporting data down, as shown in the diagram below, into direct emissions sources (such as fuel used in energy generation and company vehicles) as well as indirect emissions (such as imported electricity). This has been possible through the use of the international accounting tool, the GHG Protocol and the UK Government’s ‘Environmental Reporting Guidelines: Including streamlined energy and carbon reporting guidance March 2019 (Updated Introduction and Chapters 1 and 2)’. Our methodology and reporting process is validated annually by external GHG reporting specialists.

Annual Total GHG Emissions Trend

From 2020 onwards our reporting will be on a calendar year basis from 1st of January to 31st December (previously 1st April - 31st March). This helps us to align our GHG emissions calculations with the data that we receive from our suppliers of imported renewable electricity. The graph shows the trend of Guernsey Electricity’s Total GHG emissions since 2012.

Source of Energy 2020

This pie chart shows the source of energy as a percentage, including the electricity generated from oil at our power plant and the electricity that we import from renewable sources. Solar includes the electricity generated from our community scale solar panel arrays as well as a portion of our imported electricity which is from solar.

Green House Gas Emissions

The latest figures of Guernsey Electricity's Green House Gas (GHG) Emission figures by Financial Year.

Source Reporting Year
2020
(Tonnes of CO2 equivalent)
Comparison Year
2019
(Tonnes of CO2 equivalent)
Scope 1: Fuel consumed in GEL's Vale Power Station to generate electricity, fuel used and fugitive emissions across our our distribution network, and our company vehicle and plant. 20,270 139,600
Scope 2: Electricity consumption in networks, electricity transmission and distribution losses and electricity consumed in GEL’s office buildings. 285 109
Scope 3: Electricity lost in the transmission across the Channel Islands Energy Group (CIEG) transmission network. 1,855 863
Total Emissions 22,410 140,572
Intensity of distributed electricity
(grams CO₂ equivalent/kWh)
68 410
Lifecycle Intensity of Distributed Electricity (gCO2 equiv. kWh) 87 488
Note

Emissions are calculated for the financial year running from 1st of January to 31st December.  

The figures stated are Carbon Dioxide equivalent intensity, which means that for every unit (kWh) of energy produced in a single quarter, an average of the figure shown equals the grams of CO₂e emitted.

Emissions of the greenhouse gases; carbon dioxide, methane, nitrous oxide and fluorinated gases (hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride) are all included in our reporting, they are all presented in the form of CO₂e.

Emissions associated with imported energy, provided to us from our electricity provider EDF through a guarantee of origin certificate, which includes a gCO2e/ kWh our of supplied electricity, for both direct and indirect emissions.

Our emissions are broken down into the following scopes, as defined by the Greenhouse Gas (GHG) Protocol:

  • Scope 1: Fuel consumed in GEL’s Vale Power Station to generate electricity, fuel used and fugitive emissions across our our distribution network, and our company vehicles and plant.
  • Scope 2: Electricity consumption in networks, electricity transmission and distribution losses and electricity consumed in GEL’s office buildings.
  • Scope 3: Electricity lost in the transmission across the Channel Islands Energy Group (CIEG) transmission network.
  • Gross Emissions

Whilst we capture the indirect GHG emissions associated with our imported electricity which we report in our lifecycle intensity value, we currently only report on scope 3 emissions from the electricity lost in the transmission across CIEG transmission network.

We have reported two intensity values (gCO2equiv./kWh):

  • Intensity of Distributed Electricity - the intensity of GEL's scope 1, 2 and 3 emissions per kWh of electricity sold to our customers.
  • Lifecycle Intensity - this is the carbon intensity of delivered electricity, taking into account the full lifecycle emissions of each electricity source, which includes emissions associated with: materials used for plant constructions; embodied carbon for each type of generation technology (including GEL owned and for imported electricity); on-site operations; the supply chain of fuels; and transmission and distribution losses.
