Jersey's offshore wind proposals

In October 2023, the Council of Ministers announced plans for an offshore wind farm that could be built in the southwest of Jersey's territotial waters. The project could offer significant environmental and economic benefits for the Island.

The proposed wind farm, with a capacity of up to 1,000MW, would produce enough electricity to meet Jersey's needs with any extra power being exported.

In April 2024, the States Assembly agreed that:

Jersey should pursue the opportunities arising from the development of offshore wind in the south-west of its territorial waters
development of up to 1000MW should be encouraged in order to meet the needs of Islanders, power our future economy and create energy for export
the Government should bring forward appropriate policy and legislation, in 2024, to set in place a process to lease, consent, regulate and decommission a wind farm

Why offshore wind

Opportunities and benefits in Jersey for offshore wind

Offshore wind can present significant opportunities and benefits for Jersey. These include:

environmental benefits: Locking in access to low carbon energy that our net zero transition requires
economic benefits: Creating a new energy export sector bringing attractive, high value jobs to the Island, and new tax revenues to support public services
strategic and social benefits: Greater energy security and sovereignty, greater protection from energy price volatility, and an enhanced reputation as a forward looking and ambitious jurisdiction

The key driver for a potential Jersey wind farm has not been decided upon yet, the next stage of work will explore this.

Energy Policy

The Carbon Neutral Roadmap, Bridging Island Plan and Future Economy Programme refer to the need to consider offshore renewables for Jersey.

Carbon Neutral Roadmap

Strategic Policy 2 establishes an overall energy policy position, including that the Government will:

examine the options for utility scale renewable energy generation
ensure a diverse, safe and resilient supply of energy to meet the Island's future needs

Carbon Neutral Roadmap

Bridging Island Plan

Policy ME5 provides broad policy support for the development of utility scale offshore renewable energy proposals, where proposals provide a viable commercial case for a project of an environmentally and socially acceptable scale. It provides a framework for considering such proposals.

Island Plan

Future Economy

The Government's Future Economy Programme identified renewable energy as a potential growth enabler to address long term challenges of demographic shifts and low productivity. In addition to economic growth, other identified benefits include enhanced energy independence and potential long-term price stabilisation. Different types of renewable energy sources were analysed, and offshore wind was identified as having the best strategic fit, at present.

Project timeline

The project has 3 phases:

phase 1: In principle support: completed April 2024
phase 2: Legal and policy framework: May 2024 to December 2025
phase 3: 2026 onwards

Phase 1: In principle support

Phase 1 of the project established in principle support for the project. In the first phase of the project, we published information about the feasibility and potential economic benefits of developing offshore wind. We completed this phase in April 2024.

Feasibility

Feasibility work identified a suitable location for offshore wind in the southwest of Jersey's waters. The feasibility study concludes that Jersey has significant offshore wind potential within its waters and that the development and exploitation of the resource to generate low cost reliable power for the Island is technically feasible.

Initial economic analysis describes the significant potential economic opportunity an offshore windfarm could deliver for the Island.

Proposition

In October 2023, we published a report that explained the process for early consideration of the offshore wind opportunity, and the wider context for the project.

Propositions

Consultation in phase 1

We undertook a major public engagement process starting in November 2023 and which ran for 16 weeks, including public meetings, the opportunity to view visual 'mock ups', and a formal consultation survey. The consultation has now closed.

We engaged a diverse range of participants, including survey respondents, and children and young people. The consultation helped States Members understand the current views of Islanders. The consultation assessed community perspectives on the potential benefits and concerns associated with the project.

Over 70% of respondents were positive about the concept of offshore wind. While there was significant support for renewable energy initiatives like offshore wind, valid concerns were also raised about environmental and visual impacts, economic viability, and the project risks. We will consider these further as the project progresses.

We published results of the Offshore Wind consultation in March 2024, and can be found in the Offshore wind consultation report 2024.

States Assembly debate

In April 2024 the States Assembly debate raised several important issues, including the importance of ensuring environmental impacts and potential mitigations are understood before development consent is granted. We will consider these issues in phase 2 of the project.

The States Assembly voted, by a margin of 40:1 to support the following policy:

that Jersey should pursue the opportunities arising from the development of an offshore wind farm in the south west of its territorial waters
that development of up to around 1000MW in provision should be encouraged in order to meet the needs of Islanders, to power the Island's future economy and to create energy for export
to request the Council of Ministers to bring forward appropriate policy and legislation before the end of 2024 to set in place a process to lease, provide consent for, regulate and safely decommission a wind farm

See all of the Propositions comments submitted prior to the debate and the full voting record from the debate.

Phase 2: Legal and policy framework

May 2024 to December 2025

In phase 2 of the project we will focus on the policy and legislation needed to support any decision to develop offshore wind, and to ensure such development will be economically viable, safe and effective.

Setting the legal requirements

Draft legislation will propose requirements for consenting, construction and decommissioning of an offshore windfarm. It will include provisions to ensure the environmental impacts of an offshore wind farm, are identified, considered and mitigated at an early stage

Preparing the new law is a vital part of the project and will be subject to scrutiny and stakeholder consultation at key points.

Setting the policy for a formal leasing process

We will establish the process of allocating rights to develop the seabed. Once agreed, a leasing process will select a development partner for the project. In order to choose the right partner, the Government will need to be clear what it is seeking from this relationship on behalf of Islanders.

Ministers will return to the States Assembly to set out and seek support for their approach, before opening a formal leasing process.

We are undertaking a wide range of policy research which will be published ahead of a debate. As these reports are completed, we will add links to the evidence base section of this page.

Phase 3

2026 onwards

If the States Assembly agrees to move forward, a leasing process would follow. If a developer is selected, the Government would expect to negotiate an initial, time-limited lease to allow the developer to access and study the potential site, including recording environmental monitoring and other data.

Once ready, the developer would submit an application for consent under the new law outlined above. That application would be considered as the law requires and, if granted, development would then begin.

Evidence and reports

Feasibility study

This report provides:

a general introduction to offshore wind technology, environmental considerations and project economics, including summarising the current characteristics and trends of the offshore wind sector's technology and costs
an overview of the general characteristics of sites within Jersey's waters
a high-level analysis of strategic options for developing offshore wind in Jersey, followed by an assessment of the more promising project cases
the process of site selection and the approach being taken in many countries of assigning zones for the potential development of offshore wind based on a range of criteria
background to the positive benefits that are likely to be realised from the development of offshore wind in Jersey

Whilst the report does not set out to provide a detailed assessment of the socio-economic benefits, it highlights the areas that have the potential to provide an upside to the Island's economy and community.
