The Challenge

The States of Jersey wanted to enhance its understanding of the energy security and resilience of the Island of Jersey’s energy supply to future shocks. As Jersey imports the majority of its needs, it is particularly vulnerable to disruptions to its energy infrastructure. Any such disruption would be detrimental to the local economy and well-being of the Islanders. IPA and Currie & Brown were commissioned to identify key risks and options for mitigation.

Our Solution

In carrying out this work, IPA first developed a definition of energy security and resilience in the context of small island energy systems, thereby establishing which standards were appropriate for Jersey. Using these standards, IPA developed a bespoke Energy Resilience Model to assess the risks, likelihoods and consequences of energy supply disruptions for a number of scenarios specific to Jersey. Appropriate interventions, and high level indicative implementation costs were then identified and modelled to assess their effectiveness and ability to mitigate the identified risks and maintain energy supplies within an acceptable level of security.

Alongside these tasks, IPA conducted a stakeholder consultation in Jersey to discuss and confirm key risks and potential risk mitigation options. This included holding the first ever cross-sector energy consultation seminar in Jersey involving key stakeholders from the electricity, gas, and oil sectors, amongst others.

As an extension to this work, the States of Jersey asked IPA to provide recommendations on minimum stockholding levels to be included in a new Service Level Agreement with the fuel terminal operator in order to improve Jersey’s security of supply.

IPA’s engagement with key stakeholders facilitated the subsequent development of a holistic energy resilience strategy for Jersey which balanced the competing demands of sustainability, affordability and security.
