Confectionery manufacturer Tangerine (www.tangerineuk.net) will
achieve sweet savings on energy thanks to cogeneration and
trigeneration technologies from sustainable engineering group ENER-G
(www.energ.co.uk)
Tangerine is installing energy efficient combined heat and power (CHP)
systems at its Pontefract production site in West Yorkshire – where
famous brands such as Wilkinson’s Pontefract cakes and Butterkist
Popcorn are made.
Each year, Tangerine will achieve cost savings of almost £200,000
and save 630 tonnes of carbon, equivalent to the environmental
benefit of 63,000 trees.
The two-phase involved the installation of an ENER-G 500kWe
cogeneration unit in September 2010, followed by a 230kWe
trigeneration system to be commissioned in February 2011. The
smaller unit will provide electricity, heating and cooling to supply
a second production facility.
Tangerine has utilised ENER-G’s discount energy purchase scheme
which entails no capital outlay for the business. The contract is
structured to deliver low-cost, low-carbon energy onsite thus
reducing the facility’s carbon footprint whilst improving
profitability.
UK-based ENER-G is also working with Tangerine to develop CHP
solutions on a number of other sites. A multi-site roll-out will
facilitate a significant carbon reduction which is increasingly
important given the advent of the government’s Energy Efficiency
Carbon Reduction Commitment scheme.
Tangerine is the largest independent sugar confectionery
manufacturer in the UK, owner of brands such as Barratt, Lion, Mojo,
Wilkinson’s and Butterkist. Its seven UK production sites employ
approximately 1500 people and in three years, turnover has increased
from £40 million to £150 million.
Its factory in Ferrybridge Road, Pontefract, comprises two
production units - one manufacturing liquorice, gums and nougat -
and the other making popcorn, chocolate and sugar panned products.
Combined heat and power (CHP) – the simultaneous generation of
electricity and useful heat - is almost twice as efficient as
conventional power generation as the majority of heat is recovered
and used on site, rather than wasted into the atmosphere. There is
also less transmission loss by avoiding the transportation of
electricity along many miles of electrical distribution cables. The
Typical pay back period on CHP technology varies between two to four
years.
Peter Sanders, Operations Director for Tangerine, said: “We are
continually seeking ways to raise our environmental performance and
this move to on-site generation of power is a key element of our
carbon-cutting strategy. We are very pleased to be partnering with
ENER-G which is able to provide us with a total service - from
initial design to long term care of the systems. This has required
no capital investment by the company as the technology is being
supplied by ENER-G in return for us purchasing the generated
electricity at a very favourable rate.”
Anthony Mayall, Sales Manager for ENER-G Combined Power Ltd,
commented: “The challenge of this project was to design a high
quality system before the contract was placed, which involved
working with the client to understand activity on site, shifts in
energy demand patterns and future trends. This is the key to a
successful project that will deliver substantial carbon and cost
saving, with no capital outlay from the client.”
He continued: “We offer customers a flexible aftercare solution,
including a variety of service packages to meet precise
requirements. Our CHP on-board computer systems provide a two-way
communication channel to the ENER-G 24/7 remote monitoring centre.
Such intelligence means we can diagnose and resolve issues before
they become problems – providing proactive, predictive maintenance
that enables customers to minimise downtime and prolong system
life.”
ENER-G delivers small-scale 4kW to 10MW CHP solutions to customers
around the world and it offers the broadest product range on the
market, incorporating more than 1,400 installed cogeneration systems
across the globe – powered by natural gas, biogas, diesel, biogas,
propane or biodiesel.
Its UK-designed and manufactured systems are used in hospitals,
hotels, leisure centres, supermarkets and factories worldwide, and
among its high-profile customers is the British Royal family at
Buckingham Palace and Windsor Castle.
In the range up to 2MWe capacity; units can be delivered and
packaged as a single unit with the controls, heat recovery units and
engine within neat, compact, acoustically insulated enclosures
suitable for either internal of external installation. Above 1MWe,
each one of ENER-G’s cogeneration units are bespoke, with the engine
and system carefully designed to meet each specific application.
