LED streetlighting to save Gloucestershire £17 million

Skanska has started work to install 55,000 energy-saving LED streetlights throughout Gloucestershire. The upgrade is expected to save around £17 million over the next 12 years.

LED lighting uses up to 70% less energy than conventional sodium lights, offering a much longer lifespan and reduced maintenance costs. The move to LEDs will help Gloucestershire County Council to meet its carbon reduction target of 60% by 2020/21 when compared with its 2006/07 figure.

As part of a pilot scheme, the first LED lights in the £41 million upgrade programme were successfully installed in the village of Hardwicke. This new rollout, which starts 16 November, will cover all towns and villages in the county.

“After several months of detailed preparation, it’s fantastic to be getting started,” said Skanska’s operations director James Holmes. “Working alongside our colleagues at Gloucestershire County Council, we’ve trialled and fine-tuned the installation to make the process as smooth as possible for residents. Our public liaison team will be in local areas over the coming months and we look forward to discussing the plans with members of the community.”

With the help of £5m funding from government, each of the new 55,000 lights can be individually managed by the council using a central management system. It means that lamps can be checked and altered remotely, saving on engineering costs.

Cllr Vernon Smith, cabinet member for highways and flood said: “There are so many benefits to using LED lighting. They’re more environmentally friendly, reducing light pollution as the lamps are directed downwards.

“They’re great for communities because they produce a brighter, clearer light that makes people feel safe at night, and of course they’ll save us all lot of money - around £17 million over the next 12 years.”

Investment in LED street lighting was approved in February 2014 as part of the council’s budget for 2014/15 to 2017/18. The contract for the scheme was awarded to Skanska in August 2015 and is valued at £32-41 million, dependant on additional work.

The reduced energy and reduced light pollution is all very good of course, but.... what about the colour temperature?! The image seems to show very cool white in a residential area?!? What is the cost of a good night's sleep for the people of this neighbourhood? From a lighting design perspective and considering primarily who this lighting is for (people) we would suggest that a residential area should be lit with much warmer 3000K or even 2700K. The use of cool white 'efficient' LED street lighting for neighbourhoods around the world is already causing issues opposing the circadian rhythm of residents. Nathan Savage - Lighting Designer

This deployment, like the one in Doncaster announced earlier this week, highlights the growing trend of combining LED streetlight rollouts with central management systems (CMS). You can find out more about the business case for LED+Controls at the Strategies in Light event in London next week. Will Gibson, CEO of Telensa, the company behind both Gloucestershire and Doncaster deployments, will be presenting: http://events.pennwell.com/SILE2015/Public/SessionDetails.aspx?FromPage=Calendar.aspx&SessionID=12701

The Central Management System is from Cambridge-based Telensa, the world #1 in wireless street lighting controls. For more information go to telensa.com

If I understand correctly, the investment to upgrade the streetlights amounts to £32-41 million, and the benefit is an operational cost saving of £17 million per 12 years. If so, that means that the point of return on investment will be in ~22-29 years, or after 88,000-116,000 hrs of operation (~4,000 hrs per year). I really hope they use a well-designed LED luminaire from a reputable manufacturer and that they have a bullet-proof guarantee on the durability of the installed equipment...
