Reducing Energy Bills with CHP


Presentation Description

Combined Heat and Power helps make very consistent savings to energy bills. When Cogeneration systems are able to clock up even a few hours per day, annual savings of many thousands of pounds become possible. Read more on d-power-(chp)

CHP Units Reduce Energy Bills CHP Systems offer huge opportunities to save thousands of pounds on power bills every year.

How does CHP help reduce energy bills? :

How does CHP help reduce energy bills? Every combined heat and power installation can take advantage of the ‘spark gap’. This is the differential between: a) The price of gas used by the Combined Heat & Power unit (about, 3p / kWh), a nd b) The price of electricity charged for grid supply (say, 9 p / kWh at day tariff) For a single LoadTracker CHP unit, this means that savings of approximately 5p per kWh of site-generated electricity are achievable. When CHP systems are able to clock up even a few hours per day, then annual savings of many thousands of pounds become possible.

How does CHP help reduce energy bills? :

How does CHP help reduce energy bills? Local electricity off-peak rates are often so low as to make the CHP spark gap non-viable during night hours. In this scenario, the maximum operating hours at day tariff could be expected to be around 17. The Holy Grail for Cogeneration (CHP) systems is the ability to maintain uninterrupted operation. This is how cost savings are maximised, and LoadTracker CHP installations are designed to do just that. SAV Systems go to considerable lengths to identify and neutralise the causes of unwanted stoppages. On new-build projects, suggestions are provided to the consultants responsible for the plant room schematics.

CHP Systems Savings:

CHP Systems Savings On a caseload of 29 care homes which were assessed for LoadTracker CHP unit potential, average annual cost savings of £8,180 were identified. In the same vein, a series of 6 leisure centres assessed during the same period were found to have the potential for annual savings of between £11,336 and £31,142 by using LoadTracker Combined Heat and Power Systems .

CHP and carbon footprints :

CHP and carbon footprints Buildings account for nearly half of the UK’s carbon emissions, and domestic housing accounts for around 27% of the UK total. Action to reduce this pollution continues through Building Codes and Regulations. The use of combined heat and power within district heating systems is a good example of this - it can produce large benefits. The Code for Sustainable Homes (CSH) awards 6 possible ratings (or levels of attainment) for dwellings. These are strongly influenced by the expected energy and CO₂ emissions. Determination of Level is also related to the %age improvement in the benchmark Dwelling Emission Rate (DER) which can be achieved by the use of low carbon technologies like Combined Heat and Power.

Potential CHP System Pitfalls :

Potential CHP System Pitfalls Every Combined Heat and Power plant installation (regardless of manufacturer) faces potential issues such as: Escalating return temperatures, leading to overheating of the CHP unit and premature shut-down. Interference to flow patterns as soon as the main gas boilers come on line, again forcing the Combined Heat & Power system to shut-down. Ineffective utilisation of thermal storage, which means that the CHP system shuts down as soon as site thermal demand eases. All of these potential causes of Combined Heat and Power system stoppage can be successfully neutralised by appropriate design.

Potential CHP System Pitfalls (continued) :

Potential CHP System Pitfalls (continued) SAV’s CHP group can provide the guidance necessary to ensure smooth operations at every LoadTracker CHP system installation, whether new-build or retrofit. LoadTracker’s ability to continue running without interruption for long periods is highly valued by site operators. Long intervals between services help to keep LoadTracker CHP units on line. Maintenance is only necessary at intervals of 8,000 hours (for the XRGI 15G) / 6,000 hours (for the XRGI 20), or 2 years service if earlier.

To find out more about LoadTracker CHP, please get in touch with SAV Systems using the Contact Us page on the website: . We'll send you the LoadTracker CHP Design Guide to help you identify whether CHP is suitable for your project. Next we'll provide you with a sample CHP assessment for your type of project, and a pro-forma enquiry spreadsheet if you'd like to take things further. We look forward to hearing from you!
