Industrial processes and manufacturing are energy-intensive, so there is large scope for savings. As well as the general advice shown heres.
Motors
Keep them maintained A badly maintained motor and drive system can add 5% or more to your energy costs.
Replacing with higher efficiency motors If replacing a motor, ensure it is a Higher Efficiency Motor (Class EFF1). Higher efficiency motors can qualify for tax relief, through the Enhanced Capital Allowance scheme.
Supervise running time Check for motors (fans, pumps, etc.) that are running when they are not needed. A motor running without load can still use as much as 40% of the full load power.
Compressed air
Find and fix leaks Most users of compressed air can save up to 30% of the energy by simple measures such as identifying and fixing leaks.
Operating pressure Can you lower the operating pressure of the system? Typically a reduction of 1 bar (15psi) will save around 7% of the energy.
Supply of cool air Does the air compressor have a good supply of cool air for its intake?
Enhanced Capital Allowances
Although many energy saving measures involve little or no expenditure, some organisations find that they need to invest in new or upgraded equipment in order to reduce their energy consumption. The Enhanced Capital Allowance (ECA) scheme helps organisations invest in energy saving equipment in a cost-efficient way.
How it works
Capital allowances on plant and machinery are generally given at 25% a year on a reducing balance basis. However, with ECAs, businesses can write off 100% of the cost of energy saving equipment against their taxable profits within the first year of investment. Businesses claim the allowance on their income tax or corporation tax returns.
