Barriers to Accelerating Energy Efficiency in Street Lighting

Barriers Keys Points
Financial
  • Lack of understanding EE street lighting investment or perceived risk on the part of the discourse in the financial institutions.
  • Lack of faith in ULBs by financial institutions in India.
  • Poor financial strengths of ESCOs.
  • Lack of innovative market based financing mechanisms for implementing EE.
  • Private investors apprehensive of investing in public projects, more so new area like EE
  • Perceived risk of late/nonpayment by public sector
  • No familiarity of financial institutions with appraising EE projects and documentation involved.
  • Lack of financial instrument dedicated to EE in Municipal sector.
  • Lack of understanding of performance risk and pricing of risks by the ULBs and FIs
  • Lack of assets that can be hypothecated by the lender of banks
  • Small projects sizes.
Information and Awareness
  • Lack of sufficient information and understanding on the part of customer (ULBs) to make rationale consumption and investment decision on introducing EE technologies.
  • Lack of organized information on implementing street lighting projects, in forms of technologies available, key vendors and so forth.
  • Limited technical knowledge of EE projects developers.
Infrastructural Gaps
  • Baseline data of inventory of streetlights not authentic.
  • Inadequate electrical infrastructure resulting in a failure of luminaries
  • Improper billing practices by the utilities and ULB
  • Non standardized infrastructure in cities (e.g pole span, pole height)and noncompliance with the national guidelines for street lighting standards.
  • High percentage of unmetered lights.
  • Manual operations.

Energy-Efficient Street Lighting

Sr.No Features Benefits
1 Proper pole height and spacing Previous light distribution, which improves appearance for safety and security
2 Proper luminaire aesthetics Blends in eith the surroundings.
3 High lamp efficacy and luminaire efficiency Minimizes energy cost
4 Life of the luminaire and other components Reduces lamp repalcement costs.
5 Cost effectiveness Lowers operating cost
6 High lumen maintainance Reduces lamp replacement costs.
7 Good color rendering Helps object appear more then natural and pleasing to the public. Allows better recognition of the environment, improves security.
8 Short lamp restrike Allows the lamp to quickly come back after a power interruption
9 Proper light distribution Provides required light on the roads and walkways.
10 Proper cut-off Provides adequate optical control to minimize light pollution
11 minimizing light pollution and glare reduces energy use
12 Automatic shutoff Saves energy and maintenance costs by turning lamps off when not needed.
