NEWJEC Inc. I L J R 18-046 Final Report Summary Summary 1 OVERVIEW OF GUYANA 1-1 LAND, NATURE Guyana (the Co-operative Republic of Guyana) is a country located in the northeastern part of the continent of South America, surrounded by Venezuela at the western end, Suriname at the eastern end and Brazil in the south. And the land area is 215 thousand square kilometers, about half the size of Japan. The majority of the country is covered with tropical rain forests, and plains with a lot of fertile and swampy fields are spreading along the estuary of the river flowing from this tropical rainforest. In particular, most of the population live in the coastal area of the Demerara River estuary where the capital city Georgetown is located. Also, mineral deposits are found in the inland parts of the south, and the southern border is formed of highlands and high mountains. As for the temperature, the annual temperature change is small with the average maximum temperature being 31.8℃ and the average minimum temperature being 26℃ in the data from 1954 to 2016.As for rainfall, there are two rainy seasons in a year, with the rainfall amount increasing from May to July and December to January. In this Project, all sites where equipment and materials are procured and installed are coastal areas. 1-2 SOCIO-ECONOMIC SITUATION At the time of independence from Britain in 1966, Guyana was a socialist state, but later adopted neo- liberal policy. After that, the administration by the People Progressive Party (PPP) continued, but in 2015, "A Partnership for National Unity (APNU) and Alliance for Change" won and they are now responsible for the administration. Main industries are agriculture and manufacturing industry. The export value in 2016 is 1.45 billion USD, in particular, the rice accounts for 12% of the export value, and many workers are engaged. Meanwhile, the import value is 1.62 billion USD. The GDP of Guyana has grown about twice in the past 10 years and the GDP of 2017 has reached 3.7 billion USD. The per capita GDP is 4,800 USD which is classified as lower in the Caribbean. However, in recent years oil fields were discovered in coastal areas of the country, production is expected to start within a few years. Therefore, there is a possibility of achieving rapid economic development in the near future. The Preparatory Survey for the Project for the Introduction of Renewable Energy and Improvement of Power System in the Co-operative Republic of Guyana Summary Final Report 2 BACKGROUND AND OVERVIEW OF THE PROJECT Regarding the situation of power supply and power demand in Guyana where the power supply reserve ratio was about 22% in 2014, it can be said that the power supply level is stable, and the electrification ratio reaches a high level of 81%. On the other hand, the problem remains to secure efficient and stable power supply, because the electric power loss ratio has been at a record high over the last five years varying between 30% and 40%. Also, the system average interruption duration and the frequency of power failure are still high. On the other hand, in Guyana, CARICOM (Caribbean Community) head office secretariat has been established, leading the economic development of the Caribbean region. The Japanese Government expressed its support to CARICOM in Trinidad and Tobago in July 2014, and in the energy field, to utilize Japan's technologies and knowledge such as renewable energy to enhance support for the problems they hold. Regarding renewable energy, the introduction of grid interconnection type solar power generation facilities in Guyana is only 8.7 kW on the rooftop of the Guyana Energy Authority. However, CARICOM has set a high goal of raising the renewable energy introduction rate within the region to 48% by 2047 on the basis of equipment capacity. Therefore, the introduction of the equipment in early stage for its demonstration, development of related law, and improvement of operation and maintenance method are desired. Against this backdrop, Japanese government has received a request from Guyana Government for the introduction of GPL’s (Guyana Power and Light) transformer / distribution facility, photovoltaic power generation facility and BEMS (Building Energy Management System) at CARICOM headquarters, and a preparatory survey of this Project was conducted. 3 RESULT OF SURVEY AND OUTLINE OF THE PROJECT 3-1 RESULT OF SURVEY This preparatory survey was conducted during the period from June 2017 to May 2018, during which three field surveys were conducted. The period and purpose of field survey are as follows.

(1) Technical loss reduction for GPL The following objectives are achieved by implementing the components show in Table2. - Enhancing power supply reliability and reducing technical loss by introducing reactive power compensator in the Project target areas. - Enhancing power supply reliability and reducing technical loss by improving distribution network in the Project target areas.

(1) Soft componet (Techinical Assistance) Plan for GPL Since this will be the first time to install a static condenser in Guyana at transmission level, it is aimed to conduct the necessary technical assistance to ensure sustainable operation and maintenance of the equipment by supporting ‘How to patrol and inspect’ and ‘How to deal with abnormalities’. (2) Soft componet (Techinical Assistance) Plan for CARICOM Since there is very limited expertise (or technical know-how) on operation and maintenance of PV system and BEMS in both Guyana and CARICOM, it is aimed to conduct the necessary technical assistance to ensure effective operation and maintenance of the equi pment. And after commissioning, the PV system is intended to achieve the expected power generation output continuously and without impact toward the distribution power grid. Also, we expect to achieve the targeted energy savings through effective utilization of the BEMS. 4 IMPLEMENTATION SCHEDULE Implementation schedule is as follows.

PROJECT EVALUATION 5-1. Relevance Regarding the validity of the Project, the Project will directly solve the problems of power loss and power supply reliability that GPL has, by installing reactive power compensators and procuring distribution equipment and materials. These components will greatly help to improve GPL’s profitability and reduce CO2 emissions emitted from thermal power plants. Therefore, this Project has high relevance. In addition, this Project will
