The Parish of St Clement and Jersey Electricity (JE) have signed an agreement to decarbonise the Parish Hall by switching its heating system to an energy efficient air source heat pump, installing a solar PV (photovoltaic) array on its roof and installing public electric vehicle (EV) charging points in the public carpark. 

The heating system is being funded by the Parish while the solar installation and EV chargers will be funded by JE. Work is due to start over the summer months completing in the autumn.

Roof and cavity insulation is being upgraded at the Parish Hall ready for the heating system, which will be installed by Isle Eco who explored various innovative low carbon options with the Parish. Air source heat pumps are up to 500% efficient and can be around 60% cheaper to run than oil or gas heating.  This means that for every one unit of electricity to power the heat pump, up to five units of heat are produced from the system and fed to its radiators and into the building.

The 71kWp solar installation will export locally-generated electricity directly to the local grid for use in the community or to the EV chargers as they are used and will generate enough energy to power the equivalent of 10 fully-electric homes each year.

Two Evolve charging points will be installed in the free public car park, taking the number of charging points on the Island’s Evolve public charging network to 122 and adding to the other EV chargers available in the Parish at M&S St Clement. 

Connétable of St Clement Marcus Troy said, “As a forward-thinking Parish, we’re proud to lead the way in innovation and sustainability while ensuring the Parish Hall’s operations deliver maximum value for our Parishioners. The Parish Hall’s heating system needed replacing and, combined with the rooftop solar array, the air source heat pump will reduce our energy usage and operating costs – something Parishioners were supportive of when we held a consultation on these plans at the end of 2024.”

Chris Ambler, Chief Executive of Jersey Electricity added, “St Clement has been an early adopter of several environmental and sustainability initiatives and we’re proud to partner on this transformation of the Parish Hall. Facilitating a fuel switch and installing a solar array on the roof directly benefits parishioners while the EV charger brings another charging option to the south-east coast, which is good news for our growing EV community. 

“It has been great to work with St Clement Parish which is so committed to sustainability and is taking real action and we’d welcome the opportunity to work with other parishes on reducing their carbon footprints and running costs as well as helping to generate locally grown electricity to power our homes.”

JE and St Clement have partnered most recently to install the Island’s first 4MW community scale solar farm and through the Parish Earth Partnership in 2022, in which JE worked with the Parish to densely plant and maintain a small plot of land with native trees and shrubs to increase biodiversity and aid carbon sequestration over the long term.

Your Customer Number

Your 5 character Customer Number can be found in the top right and bottom left corners of your bill.

Example electricity bill with the customer number highlighted

Daily Service Charge

The Daily Service Charge covers energy support services such as metering, billing, Customer Care, safety obligations and other energy support services.

Off-peak

Off-peak means not at the most popular time. Some of our tariffs provide discounted rates at off-peak times - for example, during certain periods at night.

Off peak charging times

Our current off peak electric vehicles times are from 00:00 to 06:59.

Dedicated supply circuit

A dedicated supply circuit is an electrical circuit that is set aside for a specific purpose, such as powering a boiler. It will work with a single appliance only.

It will have its own circuit breaker in your fuse box, and no other device or appliance will be able to draw power from it. A dedicated supply circuit ensures that appliances can draw the current they need without overloading your system, blowing a fuse or tripping an electric circuit.

Peak Load

Peak load or peak demand is a short period when the demand for electricity is at its highest.

Kilowatt Hours

Electricity consumption is usually measured in kilowatt hours, or kWh for short. Each kWh of electricity equates to 'one unit of electricity' for billing purposes. A 1kW (1,000 Watts) appliance in use for one hour = 1kWh (one unit). The cost per unit used depends on which tariff you are on.

Three phase

Residential homes are usually served by a single-phase power supply, while commercial and industrial facilities usually use a three-phase supply.

One difference between single-phase and three-phase is that a three-phase power supply better accommodates higher loads. Single-phase power supplies are most commonly used when typical loads are lighting or heating, rather than large electric motors.

Another important difference between 3-phase power and single phase power is the consistency of power delivery. Because of the variations in voltage, single-phase power supply does not offer the same consistency as a three-phase power supply. A three-phase power supply delivers power at a steady, constant rate.

kVA

A kVA is simply 1,000 volt-amps. A volt-amp, or ampere, (VA) is the voltage times the current feeding an electrical load.

Embedded generator

Embedded generators like wind turbines and solar panels are connected to your electricity supply and provide electricity for onsite use. They also have the capability to export back to the grid.

Smart Card Number

Your Smart Card Number is the 19-digit number displayed below the barcode on your Smart Card.

The Smart Card Number also contains your six-digit Meter Number that is also displayed on your meter. You need this to top up a Smart Pay As You Go Meter whether at a Payzone outlet or online.

F-Credit

F-credit is a Pay As You Go meter display and means Friendly Credit. It is the period between 9pm and 8am. If the credit on your meter runs out during this period, your supply will remain on until 8am.

Decarbonise

The process of reducing carbon by replacing fossil fuels with fuel that is less harmful to the environment such as low-carbon electricity.

Regenerative braking

With conventional braking systems, the kinetic energy that was propelling the vehicle forward gets converted to unwanted and wasted heat by the friction of the brakes.

Regenerative braking recaptures much of the car's kinetic energy and converts it into electricity, so that it can be used to recharge the car's batteries.

In addition to improving the efficiency of a vehicle, regeneration can significantly extend the life of the braking system, as the mechanical parts will not wear out as quickly.

Power factor

Power factor is the ratio of useful power in kilowatts (kW) to apparent power, measured in kilovolt amperes (kVA). A perfect power factor would be 1.0, however in reality this is almost impossible to achieve. Office buildings are usually between 0.98 and 0.92. Bad power factor is anything below 0.85.

Electric flow boiler

Electric flow boilers are simple to install, quiet in operation, 100% efficient and integrate into most existing radiator or underfloor piped systems. Plus, with no flue or storage tank, an electric boiler is a space-saving option that can be installed almost anywhere in your home.

Approved heating system

A heating system, approved by Jersey Electricity, on a dedicated supply for use on one of our discounted heating tariffs.

To learn more about what's required for an approved heating system, view our current approved heating guidelines.

20-digit payment code

The 20-digit payment code is issued with your receipt for a Pay As You Go (PAYG) meter top-up. If your meter did not charge automatically, you can do it manually with the payment code. Press button A on your meter then key in your 20-digit payment confirmation code on the meter keypad, then press button B. Your meter will recognise the amount paid and charge accordingly.

Single phase

Single-phase power supplies are most commonly used when typical loads are lighting or heating, as in a domestic home, rather than large electric motors and higher loads. Single-phase power is a two-wire alternating current (AC) power circuit.

Energy Performance Certificate (EPC)

To access up to £9,000 government heating incentive, you will need an Energy Performance Certificate (EPC). We can help arrange this for you.​

The Government's low carbon heating incentive is a financial incentive to help move households and businesses away from fossil fuels.​

Those with an oil or gas heating system can now apply for up to £9,000+ match funding towards a low carbon alternative.​
