CHARGING AHEAD
Following on from Lighting Journal’s recent series on EV charging, one manufacturer outlines its five key things to consider when installing an onstreet charge point
By David Hall
The government has the unenviable task of managing one of the world’s most significant, and important, transitions to occur in industry for a very long time. Perhaps the most important to happen in motoring, ever. The government’s Road to Zero strategy aims to be net-zero by 2050 [1]. The sale of new conventional petrol and diesel cars will also be phased out by 2040 (and now brought forward to 2035) to support this ambitious goal.
The Department for Transport said its £400m public-private Charging Infrastructure Investment Fund will see thousands more charge points installed around the country. The UK currently has approximately 11,000 public charging locations providing 30,000 EV connectors [2]. Whilst that is quite impressive it is still a cause for concern.
One factor that impacts on our industry enormously is the lack of charging infrastructure available. While charge point numbers are increasing, the UK is still some way short of what it needs, and this feeds into consumer EV ‘range anxiety’, in turn dampening demand.
HOME AND WORKPLACE CHARGING It is claimed 90% of people who charge their electric car do so at home. The government has set out ambitions for all new homes in the UK to be built with the provision of EV charge points, a world first [3]. But while charging at home is ideal for those who have access to a drive and a charge point, for those without, charging immediately becomes more challenging. Nevertheless, as Lighting Journal highlighted in the autumn, on-street EV charging is gradually becoming more available, with a range of funding streams available for local authorities and others to tap into (‘Plug in and play?’, November/December 2019, vol 84, no 10). All this, in turn, puts street lighting and streetlamps firmly in the spotlight when it comes to EV charging.
Why street lighting? It is existing infrastructure, ubiquitous and common throughout most urban spaces. As streetlights are constantly powered, it makes sense to utilise existing street furniture, especially when adding further street clutter is not suitable or desired.
Retrofitting EV charging facilities into streetlights can often be cheaper than installing new on-street charge points, which often include expensive ‘new connection’ costs. Saying that, existing
streetlights have their own costs and complications, particularly around connections and earthing requirements. However, manufacturers such as ubitricity have made good headway in tackling this area.
As Allan Howard outlined in Lighting Journal in January (‘It’s not just a case of “here’s a vertical tube, let’s go and drill a hole in it”,’ vol 85 no 1), in order to make streetlights multi-purpose assets in this way, providing both illumination and charging facilities, the electrical infrastructure within the lighting column itself must be adapted, and done so by an approved electrician.
Although streetlights are already connected to a DNO electricity supply there are a number of considerations and requirements, particularly on earthing systems (conversion to a TT earthing system). The correct type of protection must be used and locality of nearby assets must be considered to reduce the potential of electric shock (touching distance).
At Lucy Zodion, we strongly recommend using the latest edition of the IET Code of Practice for Electrical Vehicle Charging Equipment Installation (BS7671+ A3) as your guide for installations. Work with your DNO and appoint an approved contractor to help ensure that your street lighting infrastructure is compatible and in line with industry standards.
In the event when a secondary isolator is not present, ensure you install a product such as (to use our own examples) a Trojan Midi (3-way) or Trojan Maxi (4-way), manufactured to current British and industry standards and tested to IEC/EN 60947-3 and the fuse carrier to IEC/ EN60269-1. This will provide a reliable protection. Use any service department to help manage variations, gland plates, locking options and so on, where possible, giving individual protection for both the EV charging equipment and the luminaire.
PUBLIC REALM CHARGING POINTS One thing is certain, to implement a holistic EV charging infrastructure, a mix of charging types is required, not just slow (home) and fast (7kW on-street). Public realm charging points are becoming increasingly crucial as adoption rates for electric vehicles surge. People will need to charge their cars as they go about their daily lives. Whether at schools, shopping, train stations, or airports (and the list goes on) EV charging needs to be commonplace and readily accessible, not just when at work or home. The need for convenience is paramount.
These public realm chargers will need to have faster charging times – between four hours and 30 minutes – falling into the ‘rapid’ and ‘super charging’ category. With this, of course, comes a different set of requirements. These are associated with larger power capacity, the need for new connections, either from DNO supply or perhaps even a package sub station if a large installation.
And the requirements will vary in different areas of the country, as each DNO will have its own approved products and working practices. Luckily for us at Lucy Zodion our street lighting cut-outs are widely approved across all DNO networks. Additionally, our sister company Lucy Electric has been working with DNOs for decades, supplying heavy duty cut-outs, CTCOs and package sub stations.
Given all this, we recommend five things to consider when installing a new connection for an EV charge point.
1. Plan properly – Anticipate that the process will take longer than expected and, given the increasing demand for new connections, timescales will only get longer. 2. Follow the process – Check with your DNO when ordering a new connection that you are using the right process. Many have fallen foul by not checking first, resulting in an installation that will not get approved. 3. Install Quality Products –Installing high-quality products will reduce potential issues that may arise in the future. Ensure all your products comply to the appropriate regulations and are tested regularly. 4. Consider Oversizing – Consider oversizing your supply and include some spare capacity in your EV connection and supply pillar. By making your system scalable, you can add to the number of charge points or upgrade the rating of your charge points in the future, when technology supersedes current equipment. 5. Maintain Regularly – In order to keep your equipment in good working order test and inspect regularly. It is pointless having stranded assets that aren’t serving customers and/or earning revenues.

A member since 1974, President from 2000-2001 and, until last year, the ILP’s educational and professional services manager, Stuart Bulmer has dedicated his life to the Institution and to best practice within the industry. That is why at this year’s Professional Lighting Summit he will be granted the ILP’s highest honour, of Honorary Fellowship
By Nic Paton
Since becoming editor of Lighting Journal back in 2015, I have religiously kept every edition of the magazine, so much so that my collection now takes up quite a number of racks in my office. I can therefore only imagine how much shelf-space Stuart Bulmer has to clear to accommodate to his archive.
‘I have kept every Lighting Journal since 1980,’ Stuart recalls, ‘so, yes, they are taking up a quite a lot of space!’
If you needed no other measure, this dedication to the journal alone would illustrate Stuart’s long-standing commitment to the ILP and to best practice within lighting.
But a stack of back-copies is, of course, but one small element of Stuart’s service to the Institution, both as the ILP and in its previous iterations as the Association of Public Lighting Engineers (APLE) and Institution of Lighting Engineers (ILE).
Stuart served as Regional Chair and as Vice Chair and then Chair of the technical committee in the mid-1990s.
He rose to become President in 2000 and most recently worked as the ILP’s educational and professional services manager until the arrival of Peter Harrison as permanent technical director last year.
And now, or at least as of this June’s Professional Lighting Summit in Bristol, Stuart will be able to add ‘Honorary Fellow’ to his list of achievements, as a mark of gratitude
from the ILP for his distinguished service.
Honorary Fellow is the highest honour the ILP c a n b e s t o w. There can only ever be six Honorary Fellows worldwide at any one time, with previous ILP chief executive Richard Frost having most recently been granted the honour in 2018.
‘I am very honoured,’ Stuart tells Lighting Journal. ‘The fact you can say you are one of only
six fellows – anywhere in the world – it is a great honour; I cannot emphasise that too much.’
GROWTH OF PROFESSIONALISM What, then, have been the biggest changes he has seen in the industry in his career?
‘The industry has changed dramatically. When I first started in 1974, there were still lighting engineers who were chief officers. But since then it is almost as if lighting has been downgraded,’ Stuart recalls.
‘There are many authorities who do not even have a lighting engineer nowadays; they will have what is called an “intelligent client”, or not as the case may be. The fact the county lighting engineer seems to have disappeared is a sad thing, I feel.’
The transition to LED and, from there, the connected lighting/digitalisation revolution have been further massive changes for the industry, the full ramifications of which are still being worked through.
‘Since I started, the light source has changed many times,’ Stuart says. It was mercury first, although they were changing to SOX. Then along came SON, then the Cosmopolis CPO idea came out and white light started to come in, and then LED. So it has changed many times,’ Stuart says.
STUART BULMER BY DATES
1974 – joins Tyne & Wear Metropolitan Council as a lighting engineer 1976 – joins the APLE 1980 – moves to Buckinghamshire County Council and becomes a full member of the ILE 1985 – becomes country lighting engineer for Buckinghamshire 1994 – becomes Chair of ILE London & South East region, moving on to National Council and then the technical committee, becoming Vice Chair and then Chair 1996 – moves over to Hyder as technical director, though continuing to work for Buckinghamshire 2000-2001 – becomes ILE President (and wearing his chain of office, right) 2001 – sets up his own company, SBL, but then joins URS in Bedford 2012 – reconstitutes SBL, retires from full-time lighting work, but carries on working for the ILP as educational and professional services manager
‘The main challenge to me is for the lighting engineer to make his mark, to fight his corner. There has also been the challenge, the need, for more professionalism within lighting, although I would argue we are getting there because of the ILP’s lighting courses – notably the Exterior Lighting Diploma (ELD). We have got to keep our standards high to compete with civils, mechanicals and chemicals [engineers] to ensure we can fight our corner.’
The ILP has of course also been through significant change in that time, not least in the transition from APLE to ILE and then ILP, but also in terms of the ILP’s role, and profile, in promoting and standing for best practice.
‘When I started there were very few qualified lighting engineers. Now people are doing ILP courses, they are taking an interest in getting the ELD, which is now the prime course for exterior lighting, there is no question about that,’ says Stuart.
‘The technical committee nowadays talks a different language to how it was in the old days; it is a more professional approach. We have Vice Presidents who are pushing their areas and doing sterling work. And it has been good to see the rise of people like [ILP President] Anthony Smith.
‘I can claim – because Anthony told me – to have been one of his encouragers, one of those w h o
pushed him. I could see a great engineer and lighter in him, a young person who was doing really well with his company. So, when he was looking at the education VP role, I more or less insisted to him, ‘just do it, don’t mess about’. And he has gone on from there to be President, and I consider that to be wonderful.
‘The main challenge I’d argue for the Institution is to be bringing young people through, and that relies on the lighting professional, the lighting engineer, the lighting boss, as it were, to push his people forward,’ Stuart adds. ‘There are a lot of young people, young engineers, who aren’t members of the Institution who should be.
‘The YLP has been a very good idea in that respect, because it helps us to connect with young people. It is a first-class way of doing things.
‘Another important area, I think, needs to be the encouragement of young designers coming into the industry. We have some first-class leaders from the architectural area of the profession who are members of the Institution, and we need to use them, make sure their knowledge and experience is passed on.
‘PRACTICE MAKES PERMANENT’ Finally, what has being an ILP member meant to Stuart in his career?
‘From my point of view, it was essential to be a member. I used to go to meetings, regional meetings, in London generally. And I managed from 1984 onwards to get to all the conferences. Being in the Institution was – and is – essential; you can’t do it all on your own,’ he says.
‘People often say, “practice makes perfect”, but me it’s more “practice makes permanent”. Being in the Institution was one way of making sure you didn’t get things wrong. And the fellowship within the ILP has always been second to none.
‘One thing that has always amazed me about the ILP is you can have a consultant, designer, manufacturer, contractor and engineer all together in the same room – and we all get on so well. Even though many will be in c o m p e t i t i o n , everybody gets on well. To me, that speaks volu m e s . ’ s a y s Stuart.
ILP PUTS LIGHTING ON THE AGENDA WITH HOME SECRETARY
ILP Vice Presidents Scott Pengelly and Alistair Scott met home secretary Priti Patel in January to raise the industry’s concerns around the UK’s decaying street lighting infrastructure, skills shortages and the role that light and lighting can play in helping to mitigate climate change. The 20-minute meeting came about in part because Patel is Scott’s local MP, for Witham in Essex, and was happy to engage with the ILP as part of its campaign during December’s General Election to encourage members to contact prospective
Parliamentary candidates about lighting industry issues.
‘We wanted to focus on the key areas of education and ageing infrastructure, and I think we managed to get both of those points across very well to her,’ Scott, VP – Products, told Lighting Journal. ‘On education, we raised concerns with the apprenticeship levy, the effect on STEM training, and how we as an industry have a skills gap that, as the ILP, we want to narrow. She had quite strong opinions about STEM and its usefulness; she felt there needto be better links between schools, colleges and universities and the world of work.
‘On ageing infrastructure, that was something she really engaged with. She was keen to find out what we as an industry, and the ILP as an Institution, had been trying to do to engage with government on this area. I mentioned some of the lobbying activities the ILP has done in the past few months through Tracey White and others with various MPs and ministers, notably Chris Grayling when he was transport minister, to get lighting up the political agenda,’ he added. ‘This is obviously a really good first step to getting into the heart of government. Priti seemed to have some interest and knowledge about lighting, for example recognising that good-quality LED lighting can provide sustainable solutions and SOX/SON is obsolete and should be replaced, so ticking the box there. So, it is good she has an interest,’ said Alistair, VP – Government and Policy.
‘While her portfolio as home secretary was not necessarily the most relevant within government in terms of our industry, it is great to have made this initial contact. Hopefully it may help in terms of opening doors for us to speak to other people in the future, such as transport secretary Grant Shapps and housing secretary Robert Jenrick,’ he told Lighting Journal. ‘With some of the MPs who did show an interest when members wrote to them, our hope is perhaps to organise an event whereby we can lay down our agenda and try and get some interest and traction on that. Fundamentally, what we want is for MPs to be approaching the ILP whenever they have got a lighting-related issue,’ Alistair added.

Bath’alf zebra crossing!
For Cancer Research, by Alan Read, National Sales Manager
On Sun 15th March I will be taking part in the Bath Half Marathon again, commonly known as the Bath’alf. Just to make things really interesting I will be dressed in a zebra onesie, and strapped to my back will be a Charles Endirect Belisha Beacon! If you haven’t already
guessed, the end effect will be that I am running as a zebra crossing! And, I would like to raise as much money as possible for the charity Cancer Research UK.
I am sure that almost everybody has been touched in some way, through personal experience, family, friends, or colleagues by this horrible disease. My own children have recently lost their mum at the age of just 51, and I want to do my bit by completing the half marathon again, and raise the money to continue the research into getting rid of this disease once and for all.
My employers, Charles Endirect, have already kindly pledged a generous amount money to help me raise as much money as possible. If any of you would like to make your own pledge/donation then this can be easily done using the link below.
Every donation no matter how large or small will be so very appreciated, and if you happen to be in Bath on Sun 15th March give me a wave!
