Torbay’s 16,500 street lights are being switched smarter and dimmer

Torbay street lighting is being upgraded with lower-energy technology designed to trim electricity use, cut carbon emissions and reduce running costs across thousands of lamps on the network.

At night, street lighting is one of the few public services you can see working all at once.

In Torbay, that visible glow is now being reworked to use less power, cost less to run and throw out less carbon while still doing the basic job properly: helping people move around safely after dark.

In brief:

• Torbay is changing the way its street lighting operates across the bay
• The aim is to cut energy bills as well as carbon emissions
• The programme covers around 16,500 street lights

Why Torbay street lighting matters after the sun goes down

Street lighting can look simple from the driver’s seat. A column, a lantern, a pool of light on the carriageway, job done. But for a local authority it is a long-running energy bill attached to a safety asset, and every old fitting left in service locks in another year of power use, maintenance visits and avoidable spend.

That is why programmes like this matter beyond the usual green gloss. The practical gain is not just lower consumption. It is better control. Modern street lighting systems can use more efficient lanterns and smarter operating settings so the authority is not paying to overlight roads and footways that do not need it. On a network this size, small changes repeated thousands of times become very large numbers very quickly.

Torbay’s plan is aimed at doing exactly that: reducing the energy demand from its lighting stock while also lowering carbon emissions and the council’s costs. The appeal is obvious. Electricity prices have made every legacy asset feel a bit more expensive, and lighting is one of those services that residents expect to work every single night without really thinking about the bill behind it.

The engineering underneath this is less glamorous than the evening switch-on, but more important. A typical lighting upgrade replaces older, less efficient units with LED lanterns, which produce the same useful light with lower wattage and generally last longer. That means fewer lamp changes, fewer maintenance call-outs and less disruption from works traffic. It also gives engineers more control over colour temperature, output and, where the system supports it, dimming profiles at quieter times of night.

Get that balance right and the result is not a darker place. It is a more precise one. Roads, junctions and pedestrian areas still need the right lighting class for their use, speed and risk. The point is to match the output to the place, rather than blast light everywhere because older kit gave you fewer options.

That wider shift is playing out across the sector, as authorities try to cut both carbon and recurring revenue costs from assets that once looked fixed and untouchable. We have seen similar logic in other local highway programmes, where the hidden win is often the lifetime bill rather than the installation day itself, whether that is in lighting, maintenance planning or the roads work drivers never notice until it goes wrong.

For Torbay, the numbers are substantial simply because the estate is substantial. Around 16,500 street lights means this is not a minor tidy-up. It is a network-level change to one of the authority’s largest visible asset bases. And because lighting columns sit on nearly every kind of street, from busy routes to quieter residential roads, the effect reaches far beyond a single project site.

There is also a lesson here in how highways spending now has to do several jobs at once. A lamp column is a safety asset, an energy consumer and a carbon line item. Upgrading it is not just about illumination. It is about resilience against higher operating costs and tighter public budgets. Councils do not get much applause for shaving wattage off a lantern, but finance teams tend to notice.

For residents and drivers, the immediate change may be subtle. Streets should stay lit, but with newer equipment doing the work more efficiently. For the authority, the shift is more structural: lower energy use across the network, reduced emissions and less pressure from power costs over time.

That may not sound dramatic. Then again, 16,500 lights quietly doing the same job with less waste is exactly the sort of unshowy highways story that ends up mattering for years.
