Dr. Terence Goh has more than two decades of experience in energy systems and is a subject matter expert on energy storage, micro grid and solar renewable. He has led business development and closed successfully several projects in the renewable space across the APAC region. He is an authority and thought leader on both Solar Renewable and Energy Storage and has been a keynote speaker at several international conferences (Australia All Energy Conferences 2015, 2016, Australia Energy Storage Conference 2015, SIEW 2016/ 2017). He was one of two world-wide speakers invited to Thailand’s EGAT/ PEA/ MEA/ EPPO conference in 2017 and 2018. He was also invited as a keynote speaker to CISOLAR2018, Ukraine, LCES2018 in Qingdao, China, and by the Institute of Chemical Engineering in Dubai, UAE, Dec 2018.
The project team conducted a site visit following the review of information provided by the customer to conclude a particular location as the preferred site for the first development of solar power plant on an island in the Philippines. This was concluded based on the assessment of four potential sites visited previously, taking into consideration energy reliability, future demand trend, generation capital and O&M cost, and tax and tariff structure as the evaluation criteria for bankability. The solar levelized cost of electricity (LCOE) was significantly lower for the recommended site compared to the other sites for a plant size up to 8MW over a span of 25 years.
Based on the preferred location, a preliminary solar energy production assessment (EPA) using a representative block of 1 MWDC ground-mounted photovoltaic (PV) plant was conducted, to generate a site specific, hourly time series energy production profile. The technical modelling assumptions for the EPA was a 1 MWp system of polycrystalline silicon (p-Si) PV modules installed in 3 rows, connected to either one 880 kW central inverter (configuration C1) or forty 20 kW string inverter (configuration C2). Based on the high level long-term global horizontal irradiance (GHI) assessment conducted by the team.
The team performed an exhaustive simulation that covered a wide range of energy configurations – over 50 combinations of Solar / Bunker / Energy storage – over a lifespan of 25 years. Simulation inputs were based on demand load trends, the local power supply agreement (PSA) as well as carefully taking into account customers’ comments and their feedback.
The simulation study found that it is economically favorable to first install a 5MW solar farm that is progressively upgraded at 0.5MW per annum until the total power generation reaches 8MW so as to achieve the client’s targets of a minimum 16% IRR and an electricity tariff of 11.2295 PhP/kWhr. Based on the load profile of all the 4 feeders in the island and information provided for the 3 HFO low-speed generators and other information provided by the client multiple configurations of energy mixes were simulated.

Keynote: Modeling of the climate change impact on the alpine plants diversity of the central Greater Caucasus
Time : 10:50-11:30
Khatuna Gigauri has completed her PhD from Ilia State University in Tbilisi, Georgia. The subject of her PhD thesis was the Impact of Climate Change on the Alpine Plants Diversity of the Great Caucasus. She worked as an Assistant Professor at Ilia State University for five years. Now she is an Associated Professor of Georgian Institute of Public Affairs. She has published five papers in reputed journals (one of them is-Journal of Biogeography), the number of citations-42.
The global climate change will affect all the ecosystems around the world, but the most rapid and sharp changes are expected in high mountain areas. Many observations have shown that climate warming has already led to changes in habitats, distribution patterns and viability of certain plants. The long term monitoring program GLORIA supported by the European Union was established for monitoring of the alpine plant cover transformation. The study sites and permanent plots in the central Greater Caucasus were chosen according to the GLORIA protocol. The plant cover, abundance, distribution and soil temperature were monitored in 64 permanent plots and four summits in 2001, 2008 and 2015. The average annual soil temperature did not increase during the monitoring periods; however, there were some fluctuations in 2002-2003. Growing degree day (GDD) changed in different years, but there was no significantly increasing trend. The thermic indicator (S) decreased on all summits during monitoring period. This indicates the low degree of the thermpilization status of the monitored plots. The study has shown that grasses and sedges tend to get more benefit from local climate change. Their cover and abundance did not change as much as the indicator value of the indicator species. It was obvious that the endemics and cold-adapted species are not severely endangered and species immigration is not in case. The observed changes mostly reflect a filling process rather than succession and central Greater Caucasus has faced no climate warming on this particular stage of the research.
