Question 1

Is CHP worth it without heat demand?

Accepted Answer

Rarely. Electricity alone from a small engine rarely beats the grid once fuel, service and standing losses are counted. The case is built on the heat. A site with a swimming pool, a kitchen, laundry, process hot water, drying or space heating that runs most of the day has the load profile CHP needs. Sites with electrical load only are usually better served by solar, storage or both.

Question 2

What does hydrogen-ready actually mean?

Accepted Answer

The engine is built or certified to burn a blend of hydrogen and natural gas, and later a higher blend, without being replaced. A 20 per cent blend by volume cuts the carbon in the gas input by roughly 6 to 7 per cent. What matters commercially is that the asset is not stranded when hydrogen supply and pricing develop, and that the site is not doing the same capital project twice.

Question 3

How much maintenance does a CHP unit need?

Accepted Answer

An engine-driven plant needs scheduled servicing, typically twice a year with a major service on running-hours intervals, and service cost lands in the region of GBP 8 to 11 per generated megawatt hour on an indicative basis. Saber carries that, together with parts, fuel strategy and availability guarantees, inside the contracted rate. Maintenance is the single largest operating assumption in a CHP model, so it is a real number in the contract rather than an estimate on a slide.

Question 4

Does CHP count toward net zero or ESG reporting?

Accepted Answer

It is gas generation, so it is not zero carbon, and it should be reported as such. The honest case is that it displaces grid electricity and boiler gas together, cutting site emissions and cost at the same time, while the hydrogen pathway lowers the intensity of the same asset over its life. Any claim that reads as zero carbon on a gas engine will not survive an auditor, so Saber presents it as transitional generation with a named route down.

Question 5

How does the cost of CHP compare with a grid tariff?

Accepted Answer

Compare a delivered unit rate, not the fuel bill. The rate Saber charges covers fuel, generation, maintenance, availability and carbon, and is contracted per kilowatt hour against a term of 7 to 25 years, indexed annually. Against a business tariff that is roughly 45 per cent commodity and 55 per cent non-commodity, a well-run CHP plant on a heat-bearing load competes on the commodity element and takes pressure off the site at peak.
