Highways is responsible for around 115,000 street lights in the county – the majority of the street lights in the county.
The energy needed to power the street lights costs around £3.4m a year. We also spend around £5m on routine maintenance such as electrical repairs and replacing bulbs. In 2010 we spent over £1.5m replacing old and worn out lamp posts.
Until the introduction of part-night operation for Hertfordshire's street lights, the service generated about 22,300 tones of carbon dioxide emissions each year. Once fully implemented, part-night lighting will reduce this annual total by 30%.
