  1. PV grid penetration in public gridKosrae Utility Authority APAC – ADB meeting Manilla Fred Skilling - CEO June 2011

  2. Kosrae – Key Energy Statistics

  3. Current situation in Kosrae

  4. Energy Action Plans of Kosrae State AIM : • become less dependent on imported fossil fuels • Provide affordable and stable electricity to all Kosrae households and business BY: • Introducing more RE sources • Improving the grid-efficiency

  5. Energy Action Plans – RE section Total Capacity that KUA want to install is 400 kWh / 2009 action plans mentioned a gradually approach but can be speed-up after evaluating existing installations. under EDF-9 -> 56kWp installed and results very satisfying. • Phase 1: PV grid connected plant at KUA, ground mounted 200 kWp. • Phase 2: 100 kWp at government buildings and upgrade of KUA’s plant with another 100 kWp

  6. Ongoing1.5 MW Wave energy power plantIPP structure under a PPA with KUAEstimated purchase kWh rate: 0.10 - 0.15 USD / kWhGeneration cost: 0.02 USD / kWhOperation of wave power plant: end 2011

  7. Kosrae’s Approach • 2 high priority projects on action plan: • 1st Grid – connected solar • 2nd wave energy • KUA has started preparing both projects • in the meanwhile looking for other solutions for other technologies • KUA has started planning for IPPs (Solar-Wind Hybrid etc) • Work parallel on all these projects

  8. Funding for the additional 400 kWp PV • Rough price estimate: US$ 2,400,000 ($6,000/kWp) • Project implementation in two phases: • 150 kWp with EU EDF-10 funding (= $900,000) • 250 kWp with either use of the Japan PEC fund or a combination of a grant and a loan as matching grant. • KUA is also stimulating private investors to start an IPP (Independent Power Producer) under a PPA (Power Purchase Agreement) arrangement • Interest in this is showed by two PV companies

  9. Kosrae’s picture for 2012

  10. Why KUA’s interest in Renewable Energy ? • Before 2008 => 100% dependent on diesel • In 2008 => installed 52.5 kWp PV grid connected solar on 5 different locations: 1 car park shading and 4 rooftop installations • Results for utility very satisfactory • Wave Energy: generating cost very low => IPP • Becoming less dependent on expensive imported fossil fuels! • Provide electricity to KUA’s customers' for an affordable rate

  11. Why Grid connected PV? • The sun is the best-measured renewable energy resource in the pacific countries • Crystalline PV modules have a proven track record in the pacific • Amorphous panels are being introduced as test in Kosrae in 2008 (1 kWp) • Suited for Pacific context of limited land availability: no additional land required if the PV arrays are on roofs • Scalable technology • Low maintenance, as there are no batteries

  12. PV prices are coming down! In 2008… Kosrae: 8.17 €/Wp World prices Niue: 6.76 €/Wp

  13. Grid connected PV in Kosrae • The previous table showed prices in Euro • Today the price of grid connected PV solar (installed) is between USD 4.50 / Wp and USD 6.75 / Wp installed in the Pacific. • This means that from 8 euro (= USD 11.25) the price went down to USD 5.50 or more than 40% !

  14. Current trend… • Currently, projects in the Pacific can expect: • PV modules: 3.00 – 4.00 US$/Wp • Inverters: 0.50 US$/W • Installed systems: 5.50 US$/Wp And theseprices are going down…

  15. PV Grid connected systems in Kosrae

  16. System Overview • Crystalline modules chosen for their proven track record • One small system with Amorphous modules (1kW) • Extended warranties purchased on all inverters • Total of 6 systems: 5 are roof-mounted and 1 is on car park shading • Data loggers installed on all systems

  17. Price per kWh(current rate in Kosrae: 39 US¢/kWh Yes indeed… installing Grid Connected PV is a financially attractive alternative!

  18. Current Systems • 52.5 kWp installed on roofs of airport, legislature, hospital, governor’s office, and KUA car park • 1 kWp installed on the recycling plant • Installed in September 2008 • Average production 5,800 kWh/mo. • Specific yield: 1,340 kWh/kWp/yr

  19. Energy Assessment Issues Raised 1- Supply and Installation of 5 PV Grid-Connected Systems: • Faulty Inverter at the Airport installation 2- Maintenance of the PV Systems: • Issue of the Solar PV Tariff system. 3- Monitoring of PV Systems: • Monitoring of the 5 PV grid-connected systems. 4- Project Impacts: • Beneficiaries and Public awareness and perception of the PV systems.

  20. Existing PV System’s Present Status as Monitored • Faulty Inverter at airport installation was replaced in November 2010 - No problems since • Solar panels are guaranteed for 20 years, Inverters and other electronic equipments are guaranteed for 5 years • On line monitoring of the PV grid-connected systems not yet in operation but high on the wish list • All systems are performing well and as utility we are keen to increase the PV penetration to 500 kWp • Awareness and information to end-users important Next slide will give you an overview of the performance of the PV systems

  39. KUA’s and Kosrae’s future • Between 2012-2014 → 57% renewable • In 2015 ….

  40. Kosrae’s picture for 2015 • PV – 20 % • Wind – 5% • Wave – 50 % • Diesel – 25% • In other words: 75% renewable

  41. Concluding note: • PV grid connected solar systems is a viable option for Kosrae • 1st phase additional 400-500 kWp • 2nd phase 500-750 kWp • 1.5 MW Wave Power plant in progress • Kosrae and KUA are actively looking for energy efficiency measurements – DSM and SSM • KUA interested in SMART-grid • Together we are working on becoming less dependent on the pollutive and expensive fossil fuel
