Boiler efficiency up 3.1 points at a multi-site bioenergy generator.

A bioenergy generator with four plants in England, Scotland and Northern Ireland had no single platform to run its sites under three sets of rules. After Terrafa connected its four plants on one model, boiler efficiency rose by 3.1 points.

The operation

The generator runs four plants in England, Scotland and Northern Ireland, each under its own set of rules. Fuel arrives from several suppliers, and generation, availability and fuel purchasing are run by separate teams on separate systems.

What Terrafa built

Terrafa built one model across its sites. It links each supplier's fuel, the supplier contracts, generation and the rules each plant runs under, so every team works from the same live operation.

What the teams can see

Each supplier's fuel is followed load by load, and every decision is priced in pounds per MWh. Teams see how moisture and fuel quality move output and cost at each plant.

The result

Boiler efficiency rose by 3.1 points across the client’s plants. At the client’s own figures, that is worth about £465,000 to £700,000 a year at one plant. Fuel buyers can now accept, reject or reprice a load at the gate on its cost per MWh, and generation is planned against the fuel each plant holds.
