Exeter Part-Night Street Lighting | Progress update

EXETER PART-NIGHT LIGHTING WORKS
PROGRESS UPDATE – 20 May 2015

The implementation of part-night operation of street lights in Exeter began in September 2013 in Alphington and Cowick wards and involved the fitting of remote monitoring components into existing lanterns and replacement of existing lanterns that were not suitable. Similar work in Exwck and St Thomas wards began in October 2013.

Street lights in Alphington and Cowick started operating part-night in April 2014 and in Exwick and St Thomas in May 2014.

Each individual street light has a communication node fitted to it and up to 250 lighting units in an area are controlled by a Branch node located within the ward.

Communication between the nodes and branch and between the branch and central control is via air-borne radio communication and can be accessed via the internet. So it is possible to allocate switching profiles to individual and groups of lights so that they can operate all-night or part-night.

The efficient operation of this remote monitoring system relies on good radio communications and the geographic location of branch controllers, so that command instructions can be issued as necessary. The lights themselves will operate during the day for a day or two when first commissioned to indicate that the lights work and then operate dusk to dawn, or part-night as required. In some instances however, lights may be on during the day for longer than envisaged, either as a result of poor communications, or faulty components. In such instances it is necessary to reconfigure the communication network within the affected area and this is very much a trial and error process, so a quick resolution is not always possible.

Conversion work began in Duryard and Pennsylvania wards in June 2014 and lights started operating part-night in November 2014.

Conversion work began in St James ward in October 2014 and in St Davids ward in November, lights in both wards will remain operational all night.

Conversion work began in St Leonards and Priory wards in February and April respectively and it is envisage that works Polsloe and Newton wards will commence during June.

The table below gives details of units converted to-date in each ward with the remaining provisional implementation programme shown in descending order.

*Although conversion works are substantially complete, there are a small number of lanterns that are of modern architectural design, or classic heritage type, that are not suitable for immediate conversion with the remote monitoring system. These lanterns may also be expensive to replace, or still have quite a long working life remaining.

As technology develops and when the bulk of the works are complete in Exeter as a whole, the wards will be revisited to see if there are affordable solutions to address these remaining lanterns.

Branch nodes, which control over 200 lighting units, have been installed in all wards, more than one in some wards. The remote monitoring equipment has also been installed where lanterns have been replaced, or developments have been taking place. These wards will not operate part-night until conversion works are substantially complete.

Some thoughts on Part Night Street Lighting ahead of switch-off on 01/04/14

Over the past few years, I’ve spoken to many people – and received e-mails from others – about the introduction of part-night street lighting in Exeter, so much so that I’ve put together some thoughts

Many thanks for your comments on the plan to introduce part-night street lighting [PNSL]  throughout Exeter over the coming months.

I have taken a huge interest in this matter and have blogged on the subject.

The journey to the introduction of PNSL in Exeter has been a long and hard road – let me try and summarise some of that journey ( trying searching the Express and Echo website for some of the background).

It is the upper-tier local authority Devon County Council (rather than Exeter City Council) that is responsible for street-lighting across the city. However they have no statutory duty to have them on throughout the night – they only have a specific duty to maintain those street lights that they do provide.

In 2006 DCC embarked on a carbon-reduction programme to reduce carbon footprint and save costs.

Currently DCC is repsonsible for over 72,00 street lights countywide (including 12,000 in Exeter), costing an estimated £3.4m in electricity (in 2011) and producing nearly 20,000 tonnes of CO2  every year.This is about 30% of DCC’s annual emissions of almost 62,000 tonnes – the equivalent of the total annual enegry use ofg 7,3000 Devon homes or a town about the size of Honiton.

With the combined pressures of rising energy prices and the need to reduce emissions to prevent dangerous climate change, DCC  has decided that action is required to reduce energy consumption in street lighting.

A number of options have were assessed, and it was decided that  the most cost-effective solution is to follow the lead of the Highway Agency and turn off non-essential street lighting from 12:30am to 5:30am.

It is estimated that this could save up to 4,000 tonnes of CO2  and reduce the present energy bill by £450,000. These emissions savings would go a long way to meet both national and local emissions reduction targets.

DCC have come up with a PNSL policy which can be found at:

http://www.devon.gov.uk/streetlightingpolicypartnightlighting.pdf

INTRODUCTION

The aim of this Policy revision is to ensure that the following objectives are met:

  •  Savings in energy consumption are actively pursued to reduce carbon emissions and the effect of rising energy costs
  •  That the night-time safety of road users and members of the community is considered at all times.
  •  That street lighting assists in the reduction of crime and fear of crime.
  •   That good street lighting design minimises the effect on the environment whilst enhancing the night-time ambience
  •  To provide public lighting that is cost effective, taking into account energy conservation and sustainability.
  •  To identify criteria for the provision of street lighting and for duration and timing of lighting operation.
  •  Existing part night lighting areas will not be changed to all night lighting except where there is evidence of night time crime occurring to no street lighting
  •  Existing all night lighting will be maintained on designated A and B roads and other routes as agreed from time to time with local police and parish and town councils. Where appropriate, reduced lighting using dimming technology will be considered, together with part-night operation of certain routes subject to a risk- management approach.

To implement the policy DCC have come up with 2 options for street lighting across the county, depending on the location,:

  • Part-night lighting in residential areas. Meaning that the hours that streetlights are on will be between dusk and 12:30am and again from 5:30am until dawn. Exceptions will apply where there are overriding safety issues.
  • All night and late night dimming lighting on main roads and areas of high night-time activity, such as town centres. Street lights will remain lit all night, but consideration will be given to dimming lighting where possible.

DCC have been rolling out PNSL across the county since and first tried to introduce PNSL for Exeter in 2010.

In April 2012, DCC Cabinet approved a £1.7m investment in a new Street Lighting Monitoring System which would allow for much more flexibility in the operation of PNSL by providing direct control of every light connected to the system.

DCC wanted to press ahead with introducing the PNSL scheme across Exeter last autumn, but direct intervention by Exeter Labour councillors   – both City and Country – meant there was a series of consultation events and presentations across the city.

We tried to get them to look at the option of replacing the current sodium lamps with LED lamps but they were not prepared to consider this.
Another concern we raised with the fear of increased crime due to PNSL. We were told that in areas of Devon where PNSL has been introduced, there have been some isolated increases of crime, but the feared increases have not materialised and in some instances the police have reported that crime rates have fallen. However, police will have access to the control equipment to switch the street lights back on if necessary, and DCC have told us that they will consider switching the lights back on if crime does increase.

The initial plans for Cowick meant that the only major A and B roads that would remain lit  – and the only major road in the ward is the B3121 Pocombe Hill/Dunsford Road running Pocombe Bridge to the First and Last junction at Cowick Street.

The other concession that the Labour cllrs got was that the plans for PNSL would be rolled out in a phased way across the city ward by ward over a period of 12 months or so.

The Labour councillors for Cowick thought that this wasn’t good enough – and pressed for Cowick Lane and Buddle Lane to be added to that list of “major roads”. It was also agreed that the lane running from Buddle Lane to Merrivale (alongside the entrance to Bowhill School and St Philips Court) would remain lit as a “walking route”.

DCC will continue to consider the effects of PNSL and will continue to consult until 6 month after the final areas are converted (the last wards are expected to be on PNSL by March 2015).

Members of the public can make comments on the PNSL scheme to DCC on the normal customer services phone number 0845 155 1004, but residents can only use the form on DCC’s dedicated website for Exeter PNSL

http://new.devon.gov.uk/streetlighting/part-night-lighting/partnightlighting-exeter/

They can also e-mail:

lighting@devon.gov.uk

or write in to:

Street Lighting, Devon County Council, Matford Lane offices, County Hall, Topsham Road, EXETER EX2 4QW.

I suggest that any comments on PNSL in Exeter are directed to DCC, but can I suggest that you keep your local (ECC and DCC) councillors informed on what you’ve said to Devon County Council

I have asked DCC to update their “dedicated” website on PNSL to take account of the new routes that will remain lit – and the current proposed schedule (DCC are reluctant on this point “as they wish to learn from the PNSL roll-out in Alphington and Cowick)

Like you, I am still waiting to see the comments on the consultation posted on the site – they were promised for the end of February!

I have been told that DCC plan to issue a media release in the next day or two to annouce the commencement of Exeter PNSL – I await this with interest

I am looking  forward to seeing the stars over Exeter over the coming months and I hope that the fear of crime is not realised by an increase in actual crime. By introducing PNSL, DCC will hope to save a significant amount of money – enabling them to protect other essential services.

But please be advised, I and my Cowick colleagues will continue to monitor how the PNSL policy affects residents in the ward.

COWICK NEWSLETTER [Winter 2015] | #CowickPNSL

In Cowick , part-night street lighting (PNSL) has been in operation since April 2014

Over those 9 months, your Labour team have heard your comments: the street lights have  been on during daylight hours; they were coming back on at 6am rather than 05:30; and that you were worried about an increase in crime.

Paul Bull said: “Since PNSL started, you Labour cllrs have been getting regular updates from PC Mark Oliver of the local neighbourhood team. These show that there has been NO increase in reported crime. but we will continue to keep a close eye on this data and act if we feel the situation is changing”

On the opertional matters, cllrs called for a meeting with Devon County Council officers responsible for street lighting in Exeter and that meeting finally happened just before Christmas

Paul summarises what happened at that meeting. “We highlighted your experiences and concerns over part-night street lighting, and in return DCC officers acknowledged that the introduction of the policy hadn’t gone as smoothly as they had hoped.

“They were problems but we were told that these had been sorted. DCC have also promised to do more to inform the public about PNSL – about both the problems and the progess.”

At the final Council Council meeting of the year,  Cllr Roy Hill asked a series of questions about PNSL and in what circumstance the streetlights would be switched on.

Roy asked if the street lights could be left on throughout the night following Christmas Eve and New Year’s Eve, when many more residents would be out and about on the darkened streets.

Unfortunately this most sensible this request was turned down as ‘against the PNSL policy’.

In addition, Roy asked if the lamps could be turned on during adverse weather conditions (such as snow) and he highlighted the concerns of those people who had to go to work whilst the lights are

The answer to those people out and about at that time was “carry a torch”

To which Paul would like to add: “I remember from my youth a jingle that told people to ‘wear something bright at night’. It seems that good advise in back in fashion!”

The history of Part-Night Street Lighting in #Cowick

It’s been a long convoluted journey leading to the introduction of Part-Night Street Lighting [PNSL] in Cowick on All-Fools’ Day on 01/04/4.

Devon County Council have been keen to introduce a scheme of switching of  non-essential street lighting between the hours of 12:30am and 5:30am for many years.

A new street lighting policy was approved in July 2007 (ref: EEC/07/216/HQ)

A decision to implement part night lighting in residential areas was approved in January 2009 (ref: EEC/09/8/HQ).

MWN announced the start of PNSL in Big Switch-Off in Devon on 08 October 2009

Back in 2009 justification was as a carbon saving measure (It is estimated that PNSL across the county could save up to 4,000 tonnes of CO2, but of late all the rhetoric has been about cutting the budget and saving money.

By August 2010, there was talk of a 6-month trial period of PNSL in Exeter – as reported by WMN in Council leaders are considering Part-night street lighting (28 Aug 2010).

I was selected to stand as Labour and Co-operative candidate in November 2010.

In December, I wrote A Bright Idea? highlighting the environmental advantages, but asking for the views of residents.

Just after i was elected in May 2011, I wrote to DCC asking what was being planned – but I received no response.

The next we heard was that  in April 2012, DCC Cabinet agreed to purchase a Street Lighting Monitoring System at an estimated cost of £1.7m

This was reported by WMN on 11 April 2012 in £1.7m cost of technology to turn off street lights.

The report carried a quote from Cllr Stuart Hughes, Cabinet Member for Highways and Transportation:  “The new system would allow the council more flexibility to manage, monitor or dim lights progressively, as traffic and pedestrian numbers dropped, and turn them on and off as needed.”

 Then in early 2013, we heard a rumour that DCC were planning to introduce PNSL across Exeter – no details, no timetable, nothing.It was thought DCC would just turn the lights off all over the city without any consultation – perhaps even doing across Exeter on one night?

The consultation on Exeter PNSL was (apparently) launched at the beginning of May 2013, but I first found out about the proposals almost a month later!

On 06 June 2013 Express and Echo outlined the PNSL proposals in a article In the dark? Much of Exeter faces blackout

Devon County Council has a dedicated website about PNSL for Exeter, and under proposals states: “Outline proposals have been developed with the help of local councillors, the police and other stakeholders.”

What that really means is that councillors both Exeter City Council and Devon County Council demanded a Members’ Briefing with DCC’s Street Lighting Team and Cabinet Members to discuss how PNSL would work in Exeter.

Once the consultation was underway, I wrote another Storify, Is DCC taking a dim view of Exeter with it’s *consultation* on PNSL?

Some of those themes were developed in More on PNSL

In  September 2013, E&E was talking about a leaked police report that raised major concerns over PNSL plans

Update on #ExeterPNSL

Back in December I was part of delegation of West Exe cllrs who met with officers dealing with part-night street lighting for Exeter.

One of the topics I raised was the lack of information about problems and progress.

This update from Devon County Council showing the progress in the implementation of part-night lighting in Exeter indicates they have taken note of those comments.

The update will be formally presented at the Exeter HATOC meeting of 27 January and will be revised monthly.

EXETER PART-NIGHT LIGHTING WORKS      

PROGRESS UPDATE – 16 December 2014

The implementation of part-night operation of street lights in Exeter began in September 2013 in Alphington and Cowick wards and involved the fitting of remote monitoring components into existing lanterns and replacement of existing lanterns that were not suitable. Similar work in Exwck and St Thomas wards began in October 2013.

Street lights in Alphington and Cowick started operating part-night in April 2014 and in Exwick and St Thomas in May 2014.

Each individual street light has a communication node fitted to it and up to 250 lighting units in an area are controlled by a Branch node located within the ward.

Communication between the nodes and branch, and between the branch and central control is via air-borne radio communication and can be accessed via the internet. So it is possible to allocate switching profiles to individual and groups of lights so that they can operate all-night or part-night.

The efficient operation of this remote monitoring system relies on good radio communications and the geographic location of branch controllers, so that command instructions can be issued as necessary. The lights themselves will operate during the day for a day or two when first commissioned and then operate dusk to dawn, or part-night as required. In some instances however, lights have been on during the day for longer than envisaged, either as a result of poor communications, or faulty components.

These issues have affected a small percentage of lights so far converted and the County Council has been working closely with the system manufacturer to resolve these problems. In the main, a re-mapping of nodes and their branch controllers have been sufficient to improve communications, but in some areas it has been necessary to install additional branch controllers.

The County Council will continue to work closely with the system manufacturer in implementing this new technology in Exeter and using it to its full potential.

Conversion work began in Duryard and Pennsylvania wards in June 2014 and lights started operating part-night in November 2014.

Conversion work began in St James ward in October 2014 and in St Davids ward in November, lights in both wards will remain operational all night.

The table below gives details of units converted to-date in each ward with the remaining provisional implementation programme shown in descending order.

Branch nodes, which control over 200 lighting units, have been installed in all wards, more than one in some wards. The remote monitoring equipment has also been installed where lanterns have been replaced, or developments have been taking place. These wards will not operate part-night until conversion works are substantially complete.
