This project was procured through Ameresco, as part of a competitive tender.  Ameresco were looking for a single CHP Service Provider to partner with to undertake the complete design, engineering, manufacture, supply, off-load, positioning, installation & testing of the CHP system.

The 12m 1.5MWe Supersilent (75dBA in 1m) containerised CHP had to be specially designed to fit within a 12m container and several customer specific requirements were included.  The CHP generates at 400V and all of the CHP heat (exhaust & jacket) is utilised via a LTHW supply.

The Trust also had had high requirements for low nitrogen oxide limit values which they have to adhere to due to the central London location, 2G were able to simply cater to this by adding a selectric catalytic converter.

The location of the CHP, in the basement plant room within the hospital, had specific DBA noise levels of 75dBA in 1m to meet, in order to achieve 2G incorporated an acoustic cell solution whereby noise levels are kept well below the requirements.

The particular location of the CHP in the basement plant room of the hospital brought many challenges and complexities in regards to the delivery, install and positioning of the CHP.

2G are able to deal with these challenges through meticulous planning and organisation. One of the most important stages of planning is the design process.

Taking accurate measurements of the building is pivotal to the smooth running of the execution. The measurements are taken by a 3D point cloud scan of the building which is a reliable and accurate starting block for a full 3D bespoke design of the project, which is created by our in-house experienced CAD designers.

The location of the hospital on a busy London road mixed with the positioning of the CHP in the basement brought many challenges to the delivery and install aspect of the project, seeing major road closures in the process, the many challenges included:

-  Offloading and positioning of the equipment was only possible over the top of the existing hospital from Fulham Road using a crane.

-  2G designed the engine on a split skid to allow it to be dropped into the basement as we only had a clearance of less than 50mm on each side.

-  The incorporated sound enclosure was also designed in small sections so this could be transported down the stairs as there was no other access

-  The air inlet and outlet Ductwork was extremely difficult to designed and install due to the very tight and complex area

Despite all the challenges, in April 2021 the CHP was finally delivered and in December 2021 the CHP was successfully commissioned together with a 15 year 2G service contract for the maintenance of the CHP.

With over 25 years of installing thousands of CHPs around the world, 2G are able to offer full turnkey projects with ease and experience, offering bespoke and successful partnerships with our customers not only through the design, delivery and install of our projects but beyond.
