Challenges with moving to Higher Level of RE Penetration in

Mafalu Lotolua 2016 Pacific Update Conference 18th -19th July 2016, Suva, FIJI RE Target for Power Generation – 100% by 2020

. 2-Stated Goals • To generate electricity with 100% renewable energy by 2020 (revised 2025), and • To increase energy efficiency on (main island) by 30% 100% Target

. Guided by the RE&EE Master Plan and is directly linked to the: - Tuvalu National Sustainable Development Plan (Te Kakeega III), - Tuvalu National Energy Policy 2009, - Climate Change Policy (Te Kaniva) and . Master Plan has identified the most possible proven technologies for Tuvalu to meet its 100% target. Implementation Strategies

. 60 – 95% - Solar . 0 – 40% - Wind . 5% - Biodiesel . 30% - Energy Efficiency IS

• Cannot achieve 100% renewable energy with ONE Renewable Energy source and need to include other potential PROVEN and MATURED technology, and • Energy Efficiency is also important to avoid additional renewable energy generation. Tuvalu Electricity Corporation(TEC) – Diesel Replacement

Have reached maximum level of penetration and further increase in RE will raises the potential interconnection and challenges associated with system safety, reliability and imbalances and demand . Small overall system size (and there are no interconnections to other systems) . Thermal ratings of the conductors . Limited ability of diesel generators to respond to sudden changes in renewable generation output . The loss of one operating generators can often result in fairly wide swings in system voltage and frequency . Limited RE resources . Limited land space . Lack of finance and highly depended on partners/ donor community Technical Solutions

. Using of storage to increase the PV/wind penetration and also helps in absorbing intermittent output from renewable resources and sustaining energy supply during the time when renewable resources not available. . Limit the maximum output of solar/wind generation so that maximum limit is not exceeded during brief periods when there are wind gusts or the shine fully . Smart-Grid . Using of residential roof-top or other land space such as pond, lagoon Some Innovative ways to install PV modules

. Must have sufficient funding . Need qualified staff to look after the system . Islands are separated by sea and need good internet connectivity for daily remote monitoring of the system, and . Need the on-going support of the contractor

• Good Asset Management prolongs the life cycle of an asset Lessons Learnt

. Grid Stability/Renewable Resource Impact Study is a MUST . Donor coordination in country . Establish coordinating committee between the donors and the recipient . To involve the inverter manufacturer to design an appropriate system not to affect the grid . Ensure to know the process how to claim failed equipment, mainly the major components .

• BAU is steadily increasing and with the installation of RE, the diesel consumption tend to decrease. • Diesel Saved from January – June, 2016 (6months period) –~12% as compared to the same period of 2015. Thank You
