Description

STW has a keen focus on Renewable Energy and has been utilising gas produced from the sewerage treatment process since the 1960's to provide power and heat to the same process. From the early 2000's we embarked on a journey to increase our renewable energy production by investing in new technologies such as Acid Phase digestion and more recently Thermal Hydrolysis Plants, and therefore increasing our gas yield. Currently we have a Fleet of 48 CHP Engines ranging from 190KW to 1410KW. 4 x MAN 190KW 6 x Perkins 290KW - 500KW 38 x Jenbacher (2, 3 & 4 series) 330KW - 1410KW We have an ongoing Capital Investment Programme to replace our CHP at end of life, full refurbishment @ 60,000 hrs and replacement @ 120,000 hrs. Our objective is to maximise efficiency from our Combined Heat and Power Units as an integrated part of our Bioresources Department, alongside other technologies such as Biogas Upgrading Plants which feed directly into the Natural Gas network. Therefore, the purpose of this RFI is to understand commercially available CHP engines and associated servicing kits, and spares to allow service and maintenance to be carried out by STW. We request that participants consider the following: • Base Cost of a Containerised CHP Plant - We would like information relating to your nearest option for 500Kwe, 800Kwe and 1MWe • Whole Life Cost (Unit WLC at this stage) of a Standard Containerised CHP Plant - including servicing kits • Potential to retrospectively fit a power skid into an existing container if required. • Electrical and Thermal Output • Take into account that the current servicing and maintenance of our CHP fleet is carried out by STW's own in-house team (CHP Technicians), and going forward this will be the expectation as well.
