Copenhagen replaced about 20,000 streetlights and 8,000 poles — roughly half the city's stock — with LED lanterns under a DKK 266.3m Citelum contract approved in November 2013 and carried out from 2014. The contract obliged the consortium to guarantee an energy saving, with a penalty clause behind it. A wireless network lets the city remotely dim, schedule and monitor each lamp, brightening for approaching cyclists, and the renewal replaced the switch cabinets outright, which the city called a precondition for controlling the lighting intelligently at all.

📊 Impact

The city's technical department said in 2017 that street lighting was using more than 55 per cent less energy than in 2010, with the new lanterns 70-80 per cent more efficient than the ones they replaced, and put the annual electricity saving from the renewal at DKK 12.8m. Two qualifications belong with that number: the city's own papers attribute the saving since 2010 to two programmes — the Citelum contract and a separate DKK 55m appropriation from 2011 — and the 57 per cent that circulates with this project is the reduction the contract obliged the consortium to guarantee by 2016, not an independently measured result.

🎓 Lesson

Two numbers travel with this project and they are not the same number. The 57 per cent in the 2013 committee papers is what the winning consortium was contractually required to guarantee, with a penalty clause behind it; the more-than-55 per cent the city quoted in 2017 is what it says it achieved against 2010 — and its own papers attribute that saving to the Citelum contract and a separate appropriation together. Guaranteed, claimed and independently measured are three different things, and only the first two exist here.
