3 PIGGAREP PROJECT ACTIVITY SUMMARY 1. COUNTRY: Niue 2. WORK PROGRAMME YEAR: NAME OF ACTIVITY/PROJECT: Increasing the Impact of Grid- Connected Solar PV Generation 4. Expected Dates for Implementation: April December Brief Description of the Incremental Activity and its Relation to it's Baseline: Historically the Niue power sector relies 100% on imported diesel fuels for generating power until July 2009 when 52kWp PV grid-connected systems was installed through EDF9 funds of the European Union. The Niue Power Corporation (NPC) is a trading department of Niue Government, mandated with the generation and distribution of electrical energy to the citizens of Niue. This includes end user billing, credit control, maintenance and operation and the regulatory aspects of electrical distribution and installations. Generation is primarily via diesel powered generators located at a single point (Tuila). The electrical distribution is via high voltage (HV (11,000 volt)) overhead power lines and underground cables. The volatility of international oil and the commercial reality relative to small electricity consumption market size means that the utility subsidise production costs in order to control extremely high prices for local users. Such situation has motivated the Government of Niue to consider investment in RE capabilities as strategic solution for Niue s power needs for the future. The pronouncements of the commitments were accordingly conveyed through the current Niue National Strategic Plan which says, Working towards grid stability of 20% renewable energy, and other forms of alternative energy to total electricity power supply increased to 20% by 2013 and the subordinate National Energy Policy Statement and Guidelines since Recognising financial and technical constraints, Niue have articulated a phase approach for achieving the goal of renewable energy power supply increased to 20% by Currently the implementation has started through EDF 9 supported projects focusing on energy efficiency and supply side measures. The former involving the installation of households solar water heaters plus LPG cooking appliance directly at users households, while the latter included the installation of 52kWp grid connected solar PV generation systems. In mid-2009, courtesy of the European Union, three grid-connected solar panels generators of a total of 52 kwp were supplied and installed. Thus as a result of EDF 9, Niue has installed and is operating three grid connected solar panel arrays as follows; Niue PIGGAREP Project 2010 Page 2

4 2.0kWp single inverter - Tuila Offices a small array to provide for training and development facilities June kWp 12 inverters - roof mounted solar panels at Niue High School July kWp - 18 inverters - ground mounted solar panels at Kaimiti (new hospital), September 2009 Each installation has five minute data logging facilities for each inverter and the data stream is downloaded via the GON intranet to the Tuila offices. To complete the data inputs, NPC plans to install similar five minute revenue grade metering for the two low voltage busbars in the power station. The data stream will be down-loaded to the Tuila office via GON s intranet. The objectives of EDF9 for energy are as follows: to reduce the power utility fossil fuel use and thereby controlling production costs and user retail charges; commence implementation of RE strategies and infrastructure for future power sources; provide users access to RE energy sources for heating and thereby effecting power savings from conventional generation; to improve overall domestic household hygiene and health standards; and contribute towards climate change commitments. The projects were implemented from June 2008 to December It is expected that the 52kWp grid connected solar PV systems will contribute to about 10% of Niue s current power generation from RE sources. These ongoing projects and further RE investments planned to progress under EU EDF 10 funding provides the background, base-line and cofinancing for the proposed project. For the Niue PIGGAREP, three activities have been identified which will require PIGGAREP support. All are fundamental requirements to ensure current and future RE investment is based on sound technical information and therefore contribute towards utilizing the appropriate RE technologies and measures that ultimately will maximize production, distribution and reliability from RE energy sources for all users. The purpose of the PIGGAREP supported interventions among others is to determine the impact of the grid connected solar generators on grid stability (voltage, diesel response times, etc) to assess the optimum PV penetration levels for Niue. Specifically NPC s ability to install further grid connected solar generation will be assessed after analysis of the data over at least one year s operation. NPC currently generates ~450 kwp, and total solar penetration to date is 52.0 kwp or ~12%. In addition, the preparation of a feasibility study and subsequent production of a National Energy Action Plan for Niue for the next 10 years to 2020, will enable a systematic approach to guide all future RE investments in the Niue energy sector. Activity 1 is therefore required to measure the performance and operation of 52.0 kwp on current power production which will in turn help determine the scale of RE power investment appropriate for EDF 10 and beyond. Activity 2 is required to provide the proper direction, ownership and guidance for all investments in the sector in the future including renewable. Activity 3 will provide support to the awareness activities of the Niue PIGGAREP Project 2010 Page 3

The PV systems were foreseen to contribute up to 10% of Niue s power that originates from renewable energy sources from 2009 onwards. It is also intended that further investment of 75 kwp Solar PV Grid Connected systems will be added under EDF 10 projects which Niue PIGGAREP Project 2010 Page 4

6 will include the complete HV cable replacements needed to remove current power leaks deficiency and maximise power production and reliability of supply to all users including the business sector. All three activities are foreseen important in the overall agenda of delivering RE benefits for all domestic users, communities, government, economic sector and the environment. 7. List how the project activities link to the Project Outcomes and the expected impacts of the project / activity by selecting from the list of PIGGAREP indicators. The activities are expected to support NPC s learning and knowhow concerning current and medium-term integration of renewable energy into its diesel grid and assist in terms of renewable energy awareness. Outcome 1: Deepen knowledge and knowhow in the operational co-existence of diesel and generation from renewable energy, and provide concise strategic intent in terms of national planning to increase generation from RET completed monitoring study in Niue by RET application project in Niue developed by completed feasibility study in Niue by completed projects that received TA from PIGGAREP by An additional 75 kwp installed and integrated into existing and new power systems by 2012, making a total of 125 kwp PURE projects designed and implemented in Niue by trained people at NPC on RE assessments and RE system design, installation and O&M by RET application projects designed, implemented, operated and managed by NPC staff 2012 Outcome 2: Provide an ongoing presence of RET energy awareness by energy office. 6.1 Average of 2 RE/RET awareness raising and promotion programs designed and carried out in All households in Niue are using RE for their electricity and non-electricity needs by Established and operational RE Information Unit as part of the Niue Energy Office responsibility by Total Budget for the activities (USD): $80, Total Budget for the activities in 2010 (USD): $80, Implementation Details Niue PIGGAREP Project 2010 Page 5

7 Activity 1 will be carried out by NPC assisted by external technical assistance contracted by NPC. Some preparatory work has been completed including class metering specifications and prices, selection of a small USA based software contractor specialising in Excel (data logger outputs are Excel CSV files) and the installation of telemetry equipment for remote data gathering. Project completion is expected within six months. Additional Requirements: 1) Purchase and install class 0.5 grade metering for the diesel generators 2) Purchase and install remote access data logging for the diesel generators 3) Integrate and automate the collection of the five data streams; a. Tuila PV b. Kaimiti PV c. Niue High School PV d. Diesel busbar #1 e. Diesel busbar #2 4) As there is no commercially available software for the PV panel loggers, NPC intends to develop and install processing software for the data streams. Development and specification will be in house with outside software contractors engage to cut the code in order to translate data to understandable reports. 5) Concurrent with the software development, will be the automation and checking of each inverter for correct operation from the inverter parameters therefore improving online real time monitoring. 6) Specify, develop and purchase analysis software with independent contractor for all of above. 7) Publish the results amongst regional member countries and energy development organizations for peer review, input and comment. 8) Make software & techniques available to others in the South Pacific using similar systems. Activity 2 will be implemented by NPC but carried out by a contractor with expertise in the fields of conventional diesel driven generation and renewable energy generation. It is expected that the feasibility study on RET and their co-existence with diesel generation systems, will help transpired those outcomes into detail activities required in the Action Plan. In turn the Action Plan produced will provide Niue with a document that will clearly provide a roadmap for Niue to systematically progress all its future investment in the energy sector in order to maximize production from renewable energy sources for the next ten years. Activity 3 will be carried out by NPC through the expected new office for energy. 10. Others Niue PIGGAREP Project 2010 Page 6
