Arjowiggins signs five-year contract extension with Cofely for provision of energy, utilities management for CHP energy center at its Chartham Mill paper facility in Kent, England

BOULOGNE-BILLANCOURT, France , April 9, 2012 (press release) – Cofely, has signed a 5 year contract extension with Arjowiggins Paper Group to provide energy and utilities management for the CHP energy centre at the company’s tracing paper manufacturing facility at Chartham Mill, Kent.

The contract extension builds on a long term relationship that has seen Cofely implement a management programme to reduce energy consumption and carbon emissions, supporting Arjowiggins’ strong commitment to energy sustainability.

Cofely’s original contract to design, build, finance and operate the CHP energy centre began in 1993.

Cofely has developed a specialist operational model to ensure the energy centre runs at maximum efficiency against multiple energy-related scenarios. Plant configuration is optimised after analysis of electricity import/export prices, gas price, and site electrical and thermal demands.

Chartham Mill is the only tracing paper manufacturing facility in the UK and first started producing paper in 1738. It typically runs two machines, with a site steam load of 18 tonnes/hour and a site electrical load of 4.5MW.


The Arjowiggins Tracing Papers business comprises two mills, Chartham Mill in the UK and Quzhou Mill in China, and is part of the Arjowiggins Paper Group.

The CHP system is based on a gas turbine and dedicated waste heat boiler, producing superheated steam, along with 4 x dual fuel (gas & oil) boilers which provide top-up steam to meet peak demands (and as a standby facility).

Additional electricity is also produced in a back pressure steam turbine where high pressure steam pressure is reduced to provide steam for low pressure users on the site.
