Ince Park Bio Power Resource Recovery Center

Project Overview

Ince RRC is the first project to be delivered by MBV Energy Recovery – an MWH Black & Veatch Joint Venture. Awarded an £87.3M Engineering, Procurement & Construction contract, construction began in 2015 and the plant will enter into commissioning in 2017 as one of the final Advance Thermal Conversion Plants to be accredited under the UK government’s Renewable Obligation Certificate scheme. MWH will then take over operation and maintenance of the plant under a separate contract.

Power is generated through and advanced gasification technology provided by Outotec Energy Products. Biomass fuel is introduced to a fluidized bed, prior to introduction of oxygen to allow syngas combustion. Subsequently steam is generated and fed to a condensing steam turbine. The turbine exhaust is condensed in an Air Cooled Condenser prior to re-use. Flue gas is treated through a scrubber and baghouse prior to discharge through the 85m tall stack which is fitted with a Continuous Emissions Monitoring System (CEMS).

A number of constraints specific to the site have introduced challenges which the project team has overcome. These include poor ground conditions (marsh with peat layers), protected species numerous watercourses and an adjacent COMAH facility. To overcome the ground conditions approximately 1,500 piles had to be driven to depths approaching 40m in some locations.

A number of suppliers and subcontractors have been used from the local Cheshire/Merseyside area, to provide services such as scaffolding, pipework and mechanical & electrical installation.

The O&M contract, initially for 5 years, with extension options, will cover all aspects of plant operation to ensure that the facility operates within permit and statutory requirements, is seen as a good neighbour and performs so as to maximise power output and hence project returns. MWH will be responsible for maintaining and managing the asset to meet agreed performance and condition requirements.

For many private clients in the biomass to energy sector the ability of MWH to offer O&M services post construction is a real value as it provides for a seamless transition from commissioning through testing to day-to-day operations; an opportunity to optimise long term plant performance.
