At Helec we can provide a full CHP feasibility study for any commercial or domestic project. We will provide detailed reports outlining the size of system needed, all design considerations and costings and savings information.
CHP feasibility studies need to examine several factors to determine the suitability and cost effectiveness of the system for your premises. At Helec we can conduct a full CHP feasibility study to determine the system required, the return on investment, the costs and the carbon savings
Helec staff can assist with this feasibility study whether it is for a new build design, or a retro-fit enhancement to an existing plant room as we are able to use our energy calculator tool to establish how much potential energy can be generated by the desired size of CHP.
In order to ascertain the best sized CHP unit we will require some information such as:
Information on your business (including operating hours, size, layout and location).
Previous Gas bill (1 month minimum, 12 months if available).
Previous electricity bill (1 month minimum, 12 months if available).
30 minute interval data for electricity (if available from your energy provider).
60 minute interval data for gas (if available from your energy provider)
Details of support boilers in kW (hot water and pool heating).
Details of water heaters used for LTDHW (low temp domestic hot water)
If it is a new build at design stage, or under construction we would look to use the theoretical thermal modelling figures based on the heat loss calculations and expected hot water demands normally obtained from energy modelling programmes via SBEM or BREEAM
With this information we will be able to show the size of CHP, its expected run hours per year and show the Co2 savings and more importantly the fuel costs saved by using a co-generation process which will look to reduce the on-site electricity bills.

We will conduct a full electricity consumption study (if required) to determine the KW energy use of your site. This gives us a clear picture of the size of cogeneration plant required to run your premises.
Heat demand is one of the largest determining factors of the suitability of CHP for your premises. CHP works best where there is a constant demand for heat. Typically, 4,500 hours of high or constant heat demand is needed to make CHP economical but bear in mind that this figure changes with the size of system, building and frequency of heat demand.
Plant Room Size and Location
Plant room size and location determines the size of cogeneration plant that is possible at your location and the ancillary pipework, ductwork, boilers et al that can be included. We will analyse your plant room size and location to determine the feasibility of installation.
With the information on plant room, heat and electricity demands we are able to specify a plant room type, design and generator that will provide a sufficient level of heat and power to your location.
Costs of System
Once a specification is made we will provide details of a number of suitable systems that will provide sufficient CHP for your location. There are variances in heat and power output between similarly sized systems and, of course, cost variances. We will provide you with a number of suitable options where available.
Cost of Installation
If required we can provide estimated costs of installation. We also provide pre-packaged plant rooms built in our manufacturing plant to decrease the amount of hot works required on-site and reduce disruption caused by installation.
Period to Return on Investment
The time to return on investment Is one of the core feasibility factors. Typically our CHP systems provide an expected time to return of 2.5 -6 years. The CHP system return on investment is determined by a wide number of factors including size and usage of the system.
Though not critical to feasibility from an energy and heat production standpoint carbon savings have a big impact on whether CHP systems are used. Energy use is reduced by as much as 40% which offers substantial carbon savings versus regular electricity generation. The
If you require a CHP feasibility study please don’t hesitate to get in touch with us to discuss your project. We are happy to provide consultation or to book in a feasibility for your site. We work with specifiers, builders and project managers and make it easy for you to find the right CHP system for your project.
