Warmtebedrijf Rotterdam

Warmtebedrijf Rotterdam was founded in 2006 to carry waste heat from the port's waste incinerator into the city's homes. It was the right idea, the OCAP of heat.

But the contracts told a different story. The city company signed take-or-pay obligations with the incinerator, sized on projections of three to five hundred thousand connected homes. Reality delivered about sixty thousand.

The gap between promise and pipes landed entirely on the public side; the incinerator had its certainty either way. The city's own auditor called the risks unacceptable. By the time the operation was sold to Vattenfall in 2022, the bill for the public purse had passed a quarter of a billion euros.

Run the method over it

This is the one-sided deal, where one party's certainty is bought with the other party's risk. Every Dutch heat project now carries that lesson like a tattoo.

Same category as OCAP, opposite architecture. OCAP contracted both sides before building and gave supply redundancy to the buyers. Rotterdam reversed the order: it committed to the volume first and hoped the demand would follow. Demand validated before investment is condition seven; here the demand was a projection.

The molecules were fine. The risk allocation sank it.

Waste heat is never free. Between the flare and the radiator stand a temperature lift, a pipe, and twenty years of delivery risk, and the whole game is who carries those three. Before you fall in love with anybody's waste heat, ask the three cold questions: who lifts it, who moves it, who guarantees it? The answers are the business case. Everything else is a slide.
