Terrella delivered the design, equipment specification, installation specification, installation supervision and commissioning of the HV & LV systems.The final electrical solution provides a load centre capable of meeting the current and future expansion potential for this brown field site.
A new paper recycling facility goes into full production as the HV & LV power distribution system is commissioned. The electrical element of the project included modifications and additions to the sites 6.6kV power distribution network. A 1.25MVA Midel filled transformer fitted with a Ringmaster RMU was installed at the depot. An additional RMU was installed on the landlords site to provide a standby HV supply to the depot in addition to the dedicated duty supply. 0.8kM of 11kV cable & containment was installed to complete the high voltage installation. A bespoke Merlin Gerin Panelboard provides the primary distribution to the recycling depot’s machinery and MCB distribution boards allow for final circuit connections.
Water Treatment Plant Upgrade
A multi-million pound upgrade to an existing CHP water treatment plant nears completion as dry commissioning works get underway in the new facility. On completion, the new plant will provide boiler water to the quality and specification required for the existing Combined Heat & Power plant and the new £330 million energy from waste CHP plant, currently being constructed on site by Wheelabrator. Terrella’s project team are providing technical support and construction supervision to the build in addition to coordinating the activities and defining the interfaces between the stakeholders. The water treatment plant will be commissioned and operating at full capacity before the energy from waste CHP plant is commissioned in 2019.
Wheelabrator is currently building a £330 million Combined Heat and Power plant at Kemsley in Kent. The Wheelabrator Kemsley facility will be able to process 550,000 tonnes of local residential and business waste fuel each year generating up to 49.9 MW of clean, renewable energy to power UK homes and businesses. Terrella’s engineers, supervisors and managers have been supporting the site owners and plant builders to ensure the enabling works, interfaces and infrastructure upgrades are defined, designed ,managed and executed on time, helping to keep this major project investment on schedule.
Financial approval was granted in 2017 for a multi-million pound biogas anaerobic waste water treatment plant in the south east. This new plant will effectively clean up the waste water generated by the manufacturing processes on site, producing a biogas by-product, which will be polished and exported into the national gas grid. Terrella project director Graham McIntosh reports gas to grid injection was achieved on schedule and on budget. The project now eneters the fine tuning and process refinement stage with as built documents being finalised.Terrella continues to provide the following engineering design, management and support roles on the project:- project management- construction management- project planning & coordination- financial control & reporting- high voltage network design & infrastructre upgrades- low voltage electrical system incorporating MCC’s, drives & distribution- earthing systems, lightning protection, lighting & emergency lighting- UPS, essential services and emergency power- automation, control & instrumentation support- AutoCAD 2D & 3D modelling and project documentation
