This page provides information on the 2020-2050 Energy Policy, renewable energy and security of fuel supply.

 

Energy Policy: Managing the Energy Transition

The Energy Policy 2020 - 2050 provides direction to the energy market for long-term planning and investment, to manage the transition to decarbonisation and increased electrification for consumers. This will ensure that Guernsey keeps up to date with global decarbonisation trends, regulations, technologies, industry practises and innovation.

The Energy Policy can be read in full, or there is a quick summary of the Energy Policy, in the downloads section.

Stakeholders across the Island, along with local energy market representatives helped to design and develop the Energy Policy 2020 - 2050. Energy providers, industry experts, and members of the public played a large role in the development of the policy. Everybody will have a role to play now, and in the future, to implement the vision. 

  • Research

    • The States of Guernsey and Guernsey Electricity Ltd commissioned a report on future energy demand in order to better understand the future energy mix on a local scale. The Energy Demand Forecast Report and Energy Infrastructure Options report are available in the downloads section. A summary of policy options has also been produced, based on the future energy demand forecast, on energy efficiency and decarbonisation. Commercially sensitive information has been redacted.
  • Energy Forum

    • Energy industry representatives were invited to join an Energy Forum. This Forum met for the first time on 22nd November 2018 to discuss the feedback that came out of the workshops. The Energy Forum have met regularly to develop the Energy Policy.
    • The Energy Forum met on the following dates and discussed a number of key topics:
      • 22 November 2018 - Industry Representatives and Workshop feedback.
      • 17 January 2019 - Update on Policy progression, CICRA: Regulation, what makes a positive regulatory environment and relationship with organisations in a regulated market, States of Jersey: Challenges faced by the energy market from a government perspective.
      • 21 March 2019 - Presentation of Draft Energy Policy.
      • 9 August 2019 - Review of Draft Energy Policy.
      • 7 February 2020 - Presentation of Final Draft Energy Policy

 

Renewable Energy

The Bailiwick of Guernsey is fortunate to be in a position where there are abundant resources of wind, wave, tidal and solar that can be utilised to produce power. The Renewable Energy Team (RET) have looked to exploit the natural resources in the waters of the Bailiwick by exploring the possibility of marine renewable energy, with Alderney working independently on the potential exploitation of their waters. Renewable energy could increase the security of supply to the Island, the Islands energy independence and reduction of the Island's carbon footprint. As the Island is located in the English Channel, with the west coast facing the Atlantic and other islands in close proximity, Guernsey is well placed to utilise offshore renewable energy.

  • Background

    • 2008 - The States of Guernsey decided to start looking into renewable energy in the waters around Guernsey, particularly wave and tidal projects.
    • 2010 - The States approved the Renewable Energy (Guernsey) law, 2010 and the Guernsey Renewable Energy Commission (GREC) was established as an independent statutory body to provide oversight of marine renewable energy in the Island's territorial seas. The Renewable Energy Team (RET) was also established, tasked with enabling marine renewable energy development within Guernsey waters. The RET support the Committee for theEnvironment & Infrastructure.
    • 2011 - A Regional Environmental Assessment was carried out. The strategic study established the likely environmental impacts associated with the deployment of Marine Renewable Energy devices in the seas around Guernsey. This was extended, in 2011, to offshore wind.
    • 2014 - At the Thetis International Conference on Marine Renewable Energy in Cherbourg a Framework for Co-operation was signed with Ouest Normandie Energies Marines. A Memorandum of Understanding (MOU) was signed with South West Marine Energy Park. These actions forged strong links with other regions.
    • 2015 - Secondary legislation concerning licensing was approved by the States in the Renewable Energy (Guernsey) Ordinance 2015.
    • 2017- The Renewable Energy Strategy was published and sets out a long term vision and strategy for marine macro renewable energy (offshore wind, wave and tidal power) in Guernsey. The document shows what levels of local marine renewable power that could be achieved as well as other positive impacts renewable energy may have in Guernsey.
    • 2020 - The Energy Policy 2020-2050 actions and outcomes will create the conditions for local renewable energy generation.
  • Marine Renewable Technology

    • There has been a lot of information available recently on developments in the marine renewable energy field, but it should be borne in mind that most of these wave and tidal technologies are still at an early stage of development. It is not anticipated that the Island will be able to receive any energy from tidal power for some years (the exact date is difficult to accurately estimate), but it is important that RET and Guernsey in general are ready to utilise these new technologies, when the time is right. Trial/small commercial projects are ongoing. For example, the Orkney tidal stream project.
    • Technologies currently being used are not yet in commercial production. This, coupled with the difficulties of the marine environment, means that energy from marine renewable sources will initially cost much more to produce than electricity produced by conventional fossil fuel based generation plants. In addition to the purchase cost, there is also the necessary cabling and beachhead connections to join the generators to the power grid. It is hoped that the Islands will be able to benefit from the renewable energy generated by our tides and possibly receive an income through the supply of surplus electrical power via the subsea electrical cable link to France, via Jersey (GJ1) or directly to France (GF1).
    • There are a number of renewable energy options that may be applicable to Guernsey.
    • Tidal current devices - these extract energy from the flow of water, and often take the form of propellers or oscillating vanes fixed to a structure that is mounted on the seabed.
    • Wave energy devices - these take energy from waves. There are a number of types of device including buoy-type point absorber devices and near-shore or shallow water devices.
    • Offshore Wind - Guernsey has a significant wind energy resource and although areas of suitably shallow water off the west coast are limited there is sufficient area for small scale development. RET is currently looking at the mature technology of monopole turbine as offshore floating turbines are still being developed. RET are continuing to monitor the progress of floating turbines as in the future there is the possibility of deploying these turbines off the west coast.
    • The above options are considered to be most suitable for Guernsey due to the geography of the region and formed the focus of the Regional Environmental Assessment of Marine Energy.  Developments are continually monitored regarding other technology options for possible future use.
    • Tidal Barrages or Lagoons -RET are continuing to monitor progress in developments of tidal range options given recent progress including the ongoing process to develop Swansea Bay Tidal Lagoon. There are a number of bays, inlets and areas of shallow water around the coast of Guernsey.

Fuel - Security of Supply (Hydrocarbons)

Following the approval of the Energy Policy 2020 - 2050 the Hydrocarbon Programme Board meet quarterly and report on the interim and long-term solutions for continuation of hydrocarbon supply to the island. 

Overall, hydrocarbons are predicted to steadily decline in usage, due to increased efficiencies in technologies for heating, lighting, and transport, and with increased electrification, energy innovation and the global transition away from fossil fuels to renewable energy and low carbon alternatives. 

The 'Not always afloat but safely aground' (NAABSA) vessels that are currently used to import hydrocarbon fuels to Guernsey have limited lifespans. Alternative, and interim, long-term solutions are therefore required and being developed. The States Energy Team regularly engage with fuel providers who are planning and developing transition to interim and long-term solutions for continued supply and security of supply of hydrocarbons to the island. In Guernsey, there will be a continued need for hydrocarbons beyond 2050. More recently local fuel providers have proved the commercial viability of unitised/containerised trailers, via roll-on/roll-off ships, supply to the island. Solutions are continually in development in this rapidly changing landscape, and the Hydrocarbon Programme Board review and monitor developments in line with agreed objectives and principles of the Energy Policy 2020 - 2050, and the Climate Change Policy and Action Plan.

  • Fuelling our future

    • As an insular community, Guernsey relies on a constant supply of fuel from off the island for many essential elements of life including petrol for cars, motorcycles, boats, buses and business vehicles, heating for our homes and offices and the generation of some of our electricity.
    • These hydrocarbon fuels (including petrol, diesel, kerosene, aviation fuel and heavy oil) are brought to the island by sea using specialist tankers. The ships collect the fuel from refineries in the UK before sailing to St Sampson's Harbour where their cargo is offloaded through pipelines to the large storage tanks that are a familiar sight at North Side, Bulwer Avenue and the Power Station. The fuel is then delivered to businesses and homes by road tanker. Although the States owns two specialist tankers (the Sarnia Cherie and Sarnia Liberty), they are used to transport only some of the products that Guernsey imports. Other vessels and importation methods are required to import the heavy fuel oil and liquid petroleum gas. The States Energy Team work alongside fuel and energy organisations to support security of supply to the island now and in the future.
