From PFI to LED: Hertfordshire's Sustainable Street Lighting Strategy

1. From PFI to LED Peter Simpson - HCC Senior Asset Manager and Team Leader

2. Hertfordshire - The Strategic Story: 2010 - 2017 Street Lighting: • 110,000 lighting columns, 115,000 luminaires • Majority of columns in excess of 30 years old • High Density, Low pressure sodium lighting 2010/11: • £174m PFI credits secured, Government’s Public Spending Review, PFI withdrawn • Austerity agenda, Reducing Revenue Budgets, Increasing Energy Costs: Challenge • Review of Street Lighting Service: Opportunity: Develop a Sustainable Street Lighting Strategy based on Affordable, Safe & Operational principles. A two-stage approach

3. Hertfordshire - The Strategic Story: 2010 - 2017 2011/12: • Street Lighting Strategies endorsed: Part Night Lighting (PNL), Safe & Operational (Point for Point, Like for Like Replacement) • PNL: 80,300 units delivered on time, within £3.5m budget, saving £1.3m p.a. (£1m in energy), no adverse impact on road safety or crime and reduced ‘sky glow’ • Highway Services Term Contract (HST) started 1st October 2012 (includes Refurbishment) 2013/14: • Development and approval of HCC Capital Invest to Save Initiatives • CMS & LED Technology becoming more robust, reliable and affordable • Asset Management Approach: Data driven, condition led (rather than age). Testing circa 85,000 units, replaced 13,000 columns (rather than 70,000 under PFI model). Making the best use of existing infrastructure where Structurally & Electrically sound 2014/15: • CMS & LED including Variable Lighting Strategy, Ad-hoc replacements, New Works and New Developments endorsed • CMS & LED Phase 1 : A - Roads, 12,600 units, delivered on time, within £6.5m budget, saving £0.66m p.a.

4. Hertfordshire’s Approach to CMS & LED: 2014 - 2020 2015/16: • CMS & LED Phase 2 : B, C & U - Roads and Footways in Full Night Lighting (FNL), 21,400 units, delivered over 2 financial years on time, within £7.5m budget, saving £0.77m p.a. • Phase 1 and Phase 2 Pilot Projects endorsed - PNL, Dimming and Trimming 2016/17: • CMS & LED Phase 3 (Integrated within Phase 2) : Remote Footpaths and Outlying Settlements in PNL, 8,700 units, delivered on time, within £3.5m budget, saving £0.18m p.a. 2017/18: • CMS & LED Phase 4 : Remainder (B, C & U - Roads and Footways) in PNL, 70,000 units, cost £18.5m over three financial years, started April 2017, estimated saving £1.86m p.a., plus conversion of Belisha Beacons, cost £84k over 2017/18, estimated saving £31k p.a. • To date circa 50,000 units have been converted to CMS & LED (including circa 3,000 ad-hoc replacements, following column knockdowns), reducing carbon emissions (CO2) by circa 5,800 t p.a. • Value for Money: Total investment: £39.5m (22% of PFI model), total savings (energy, maintenance and carbon tax) circa £4.8m p.a., CO2 circa 12,600 t p.a.

5. CMS & LED Project Planning, Implementation and Technical Aspects • Governance: Highways Cabinet Panel, Highways Electrical Board and Project Team • Sustainable Procurement: HST Contract: Ringway, CMS: Telensa, LED: Urbis. Procurement model tests the market. • CMS: 48 Base stations (Phase 1) - low power radio network across Hertfordshire, One Tele cell Node per LED unit, Remote management, control and detection of faults • LED: ‘Soft’ White Light. Operation: Dimmed by 25%, 11pm - 6am • Structural & Electrical Integrity: Testing, surveys, Brackets and Post Top, Audit Process: 10% ‘on-site’ checking • Design: ‘Safe & Operational’ philosophy: Point for Point, Like for Like Replacement, Light Distribution & Uniformity on the ground - ‘no worse than existing’ • Innovation & Sustainability: Installing new technology on structurally sound existing infrastructure. Reduced wastage and maintenance visits whilst maximising recycling

6. CMS & LED Project Planning, Implementation and Technical Aspects • Warranties - comprehensive on products, catastrophic failure, legal involvement • Recovery of Energy Savings and Load Profile - liaison with meter administrator and energy provider • Telensa/Confirm Integration - development of interface, automatic fault generation and improving the customer journey • Continuous engagement with supply chain and Industry. All phases have run contiguously and forward plan & programme have been shared. • Holistic management of the project and routine maintenance has enabled the refurbishment / recycling of sodium lanterns (and management of their obsolescence) pending conversion in later phases • Pilot Projects - Part Night Lighting and Dimming & Trimming On site Interactive Trials undertaken. Monitoring for 12 months • Political engagement & endorsement is essential

7. Hertfordshire - Lessons Learned • Environmental benefits: Duty - Wildlife & Countryside Act 1981: Bats - Protected Species. Proactive engagement with Hertfordshire & Middlesex Bat Group • Contributed to study, trials & monitoring on how LED affects the local Bat population by Bristol University. Paper published: Outcome: LED does not affect Bat activity at street lights. • Assessments: Equality Impact, Environmental Impact, Public Health, Sustainability • Benchmarking: Visit other Local Authorities • Sell benefits: Energy & Maintenance savings, Cost Avoided, Reduction in Energy demand, Carbon Reduction, Improve Visibility, Reduction in Light Pollution • Regular Lessons Learned with Supply Chain (including HST Maintenance) - ‘One Team’, Joined Up

8. Hertfordshire - Lessons Learned • Positive Impact on Asset Inventory and Grass Cutting (night time) • Forward visibility of Programme - Logistics and Production e.g. Factory Fitted Nodes on LED’s • Light Distribution: Segregated Footways / Cycleways and Internal Shields on LED’s • Remote Footpaths - Podium Steps • GIS Mapping and Data Capture, Work Scheduling, E-Coding, Test Certificates • Sharing Knowledge of the Network - Accessibility, Availability, Group Switching • Robust Consultation and Proactive Communications: Stakeholders (including emergency services), District and Parish Councils, Public and Local HCC Members. • Shared Hertfordshire’s approach and lessons learned: Regional (ADEPT), National (HEA) and International (Portugal and Singapore)

9. CIHT Sustainability Award 2017 Winner From PFI to LED

10. Hertfordshire: The Future - Positive Evolution • Wider Implementation Potential: Pushing the boundaries - further dimming & trimming. New Code of Practice - Risk based approach, Dynamic Dimming, Smart Sensors • CMS & LED Phase 5 : 114High Masts, 19,981 Signs (includingIlluminated Bollards) and 4,142 Subway lights, estimated cost circa £1m over 3 financial years, starting April 2018, subject to funding • DfT (HMEP) & DECC - Toolkits: Effective use of Asset Condition data. Extensive testing regime has provided the foundation for a robust six-year testing strategy. Updating & Maintaining inventory is KEY • CMS, ITCC & ‘Smart Cities / Counties / Living’: Future Opportunities, Evolution of Transport and Future Highways - Internet of Things, Connectivity, Connected Automated Vehicles, Mobility as a Service
