Our flowchart will show you whether or not your project is feasible.
1. Before you do anything - save some energy
Wrap it up
Lower the lights
House of correction
2. Eyes on the size
Poor sizing can wipe out any potential gains from a CHP.
Calculate the ratio of heat and power demand:
- Morning and night
- Weekday and weekend
- Summer and winter
And all times in between – ideally on an hourly basis.
Size the plant so the vast majority of heat is used.
To be economical, CHP needs 5000 hours a year constant heat demand.
3. Watt does the future hold?
Future energy demand?
Changes to the business?
Sell excess power through the grid?
Sell excess heat into a local heat network?
4. The perfect fit?
Consider the following practicalities of installation:
- Gas connection
- Grid connection
- Heat connection & dissipation
- Ventilation air supply
- Exhaust system
- Noise regulations
- Planning consent
5. Fuel for thought
Natural gas - do you have it?
Remember you may need increased capacity and pressure.
6. The business end
How do you get the best out of the CHP?
Operations: Monitor site demand and utility costs (is it cheaper to buy in power and use a boiler, say, at night?)
Maintenance: Pay an expert to guarantee your uptime and protect your asset.
7. Money matters
Financing is a choice between owning the CHP to keep all the profit but taking all the risk.
Or you can lease it to lose the risk, but forego some of the profit.
8. Get the credit
Good Quality CHP accreditation – essential for valuable incentives.
Tax deductions and rewards for renewable CHP include:
- Enhanced Capital Allowances (ECA)
- Business Rates Exemption
- Renewable Obligation Certificates (ROCs)
- Renewable Heat Incentive (RHI)
- Feed-In Tariffs (FITs)
