1) Vanuatu PEEP2 Activities
• Energy audits & appliance & light inventories
• Urban household & energy use surveys: Port Vila & Luganville
• Energy audit training (government & private sector)
• Advice on EE for National Energy Roadmap (NERM)
• Some (limited) energy database development
• Investment project development & implementation
• Technical reports on EE opportunities
• Assistance to GoV with accessing follow‐up donor funding for sustainable energy policies & national EE targets
2) Implemented EE Projects ‐ Summary
• 7 separate investment projects (excluding ‘Bulb Eater’)
• But presented & discussed as 4 projects as some are very similar

50% Luganville
Excludes spare lights
(typically 3%)
* About 60% of these lights are for schools
2a) Street Lighting: Port Vila & Luganville
UNELCO (Vila) & VUI (Luganville ) each received 160 x 70w LED lights
(+2 spares) to replace old mercury vapour lighting
Luganville:
 PEEP replaced 75% of all street lights (based on 2013 total lighting)  All new lights installed by late 2014
 Improved lighting quality with kWh reduced by 40%* for lights replaced.
 Street lights expanded (from 215 in 2013 to 320 in early 2015) so overall kWh for street lighting have not dropped  Simple payback = 4 years
Port Vila:
 PEEP replaced 25% of all street lights (based on 2013 total lighting)
 Improved lighting quality with kWh reduced by 50%* for lights replaced
 All new lights installed by Feb 2015
 Simple payback = 6 years (due mostly to lower operating hours than VUI)
* Lighting improvement and KWh savings to be confirmed
2b) Residential Lighting: Port Vila & Luganville
Port Vila (payback = 2.5 months)
 Project based on detailed survey of 2009 responding households in early 2013
 Survey indicated 39,400 lights, with T12 & T8 FTLs accounting for over 50% of lighting electricity use.  Replacing 9,000+ lights with T5 FTLs and CFLs; focus on lower income homes
 Administered by Ministry of Climate Change, with user fee of $2.50/hh
(cost of installations) Luganville (payback = 7 months if only 63% of lights are installed)
 Based on detailed survey of 329 responding households in early 2013
 About 9,500 lights at time of survey, many T12 & T5 FTLs and incandescent. Half of these to be replaced by T5 FTLs and CFLs.
 Administered by VUI (power utility) with user/installation fee of $1/hh
 Every household should receive (on average) two new lights
 VUI to return old lights (at its cost) to Vila for processing
However, by early February 2015, very slow progress
2c) Public & School Lighting: Efate & Santo
•
•
PEEP2 and/or DoE inventoried light types, operating hours and quality
in dozens of public sector buildings & schools
Light levels (lumens) measured at sample locations to compare before and after installations
Project 9: Port Vila (expected payback period = 13 months)
• 2,432 lights found in six public buildings, of which over 2,000 to be replaced. • 11 separate light types & various luminaires; complicated tender process
• Installations about 70% complete by early February 2015
Project 30: Efate and Santo (expected payback period = 5.5 months)
• VUI met DoE costs for lighting inventories
• Nearly 5,000 lights to be replaced in many provincial and local government facilities and 26 schools on two islands (with 60% of all lights for schools)
• Mostly T8 FTLs to be replaced by T5s & incandescent to be replaced with CFLs
• Few installations completed by early February 2015
2d) High Efficiency Air Conditioning
Ministry of Finance & Economic Planning has many A/C units; Over 60% are old, inefficient split units and window systems
• Much of MFEM is exposed to the westerly sun adding to thermal heat gain and A/C demand. • Project installed highly efficient ‘variable refrigerant volume / variable flow’ (VRV/VRF) technology for office of Minister & staff
• Should reduce electricity use in the cooled area by 25‐35% or more.
• More expensive than expected; payback period is 5.8+ years (including 2 years of monitoring and O&M)
3) Summary of Benefits: Vanuatu Projects
‘Actual’ benefits were estimated assuming:
•
•

•
•
Actual equipment costs & revised estimate of full local costs
Exchange rates & electricity prices at time of proposals (2013)
kWh savings based on limited Monitoring & Verification
‘Base case’ or ‘Worst case’ if a range of design assumptions made.

4) Issued Faced During Implementation
 Poor energy data & data management for assessing & developing EE opportunities
 One project too complex: too many types of lights & fixtures
 Very slow approval, ordering, shipping & customs clearance of equipment; (so not enough time for installation and M&V):
o Most projects were designed by July/August 2013 but equipment delivery in Oct/Nov 2014 (15 months later)
o Most equipment delivered to recipients in November 2014; (but many employees/installers on leave until late January)
o Thus planned 6 month installation period was not possible
4) Issued Faced – continued (slide 2 of 3)
 Typically one month for storage, release & Customs clearance:
o Often slow (or no) notification of arrival by agents
o Time‐consuming GoV process for VAT & duty exemption
o No GoV budget for equipment storage & handling
 Some conditions changed between project design and equipment arrival:
o Cheap, poor‐quality Chinese CFLs flooded market; PEEP lights less desirable for households, very slow installations
o Air terminal advised they want different lights after new lights arrived; DoE moved to new building; Meteo has 25% more staff since energy audit & new layout; many T12s already replaced with T8s since 2013, etc.
4) Issued Faced – Continued (slide 3 of 3)
 Some Ministries unaware of their MoU obligations (no staff & funds to transport, install lights, return old lights)
 Bulb Eater not installed & operated until February 2015
o Ministries reorganised; agreed space became unavailable
o Old lights with mercury were stored insecurely, not treated
 No PEEP budget for EE awareness; almost no GoV funds
 Private hotels enthusiastic & proposals (partly) developed
(but unable to get management approval due to other priorities)
 Poor choice of contractor for A/C installation
(Many problems including multiple A/C installed at site; long delay)
5) Other Energy Efficiency Implementation
• PALS legislation for refrigeration standards & labelling
(discussed separately by SPC / Australia)
• PEEP2 Publications and Technical Reports, including:
o Two detailed urban household appliance & energy use surveys
o Home energy use guides in Bislama, French & English
• PEEP2 Energy Audit training • Input to IRENA reports & workshop including EE with RE
• PEEP2 EE Advice, including:
o Analyses & EE input to National Energy Roadmap
o Mechanism for national EE targets (to be further developed in 2015‐2016 through GGGI & GIZ)
o Improving EE for Chinese‐built International Convention Centre
(Savings unknown but could be substantial)
6) Lessons Learned and Recommendations
Lesson:
Recommendation:
Too much time between project design and equipment delivery
Easier, quicker procedures for approval & contracting
Too many light types for some projects
Simplify project designs: less range of light types
Slow Customs clearance
Easier procedures for VAT & duty exemptions
Inadequate public awareness (residential lighting)
Include awareness funding in project budget; more govt budget
Implementation very time consuming
Allow ample time for installing and M&V
6) Lessons Learned & Recommendations (slide 2 of 2)
Ministries approve projects but don’t provide agreed services (ignore MoU)
Recommendation:
More meetings with steering committee & ministry staff? Residential lighting easier to implement through power utilities
Work through utilities if practical
Lesson:
PIC suppliers generally unable to meet Education?
technical specifications or low costs
Strong private sector (hotel) interest & excellent payback don’t necessarily lead to co‐financed EE investments
Much easier to plan & implement EE on main island but good opportunities on other islands
Perhaps work with smaller local hotels who don’t need overseas headquarters approval?
Ensure sufficient travel budget to allow coverage of other islands away from the capital
