Project overview

Solar Hybrid System Project in marshall插图1

The Republic of the Marshall Islands is an island country located in the Mid-Pacific Micronesia region. It consists of 29 atoll island groups and five small islands with a total of 1225 islands. The islands and reefs on the southeast of the Marshall Islands are collectively called the Sunrise Islands, while the islands and reefs on the northwest are collectively called the Sunset Islands. There are about 208 kilometers between the Sunrise Islands and the Sunset Islands. The majority of the population of the Marshall Islands is concentrated in the capital Majuro and Ebeye Island in Kwajalein Atoll (Kwajalein).

When traditional energy sources are becoming more tense and environmental problems are getting worse, renewable energy can be said to be the most competitive power source for communities in the Pacific. As one of the regions with the highest energy costs in the world, the Pacific region is dotted with island countries. Therefore, the development of sustainable energy such as solar energy and wind energy is the best choice to improve the energy security of the region and promote economic growth.

The Marshall Islands Sustainable Energy Development Project is located in Majuro, an atoll of the Ratak Archipelago of the Marshall Islands in the Western Pacific, which is the capital of the Marshall Islands. The Majuro area includes about 60 small islands with a total land area of ​​10 square kilometers (4 square miles). The atoll has port facilities and an international airport, with a population of about 30,000 people.

The project helped Marshall Energy Company to upgrade the existing No. 1 power station, build a roof and reservoir floating photovoltaic power generation system, and provide it with an additional battery energy storage system to support the new photovoltaic power generation system.

After the project is completed, it can effectively increase the ratio of renewable energy consumption in the Marshall Islands, bringing the share of renewable energy to 7%, and greatly improving the power supply in the capital area.

The Marshall Islands sustainable energy development project includes 4MW PV power generation system, 5MW medium-speed generator set, 3.6MW high-speed generator set and 2MW/1MWh battery energy storage system, EMS energy management system independently developed by SINOSOAR and SCADA intelligent cloud monitoring The system is used to control the joint adjustment and coordination between photovoltaic, energy storage and diesel engine.

This project is the infrastructure construction project with the largest amount and the largest number of stakeholders among Marshall’s domestic projects. The project involves the installation of a megawatt medium-speed diesel generating set, the renovation of a large diesel generator plant, the replacement of the geomembrane of the reservoir, the construction of a floating power station, and the construction of a large-scale steel roof on the ground. The technical difficulty and the project implementation environment are very challenging.

After the completion of this project, it will be the main source of power supply for the entire island in the Majuro Capital Region and can completely solve the problem of insufficient power supply on Majuro Island. Maximize the use of renewable energy such as local PV to provide the region with stable and continuous power around the clock. In addition, the project can effectively improve local power supply conditions, basically solve the problem of unstable power supply on Majuro Island, and enable local residents to truly enjoy the convenience brought by renewable energy.

Project significance

  • Reduce dependence on traditional energy sources such as diesel, improve the stability of the energy system, and ensure national energy security;

  • Increase the proportion of renewable energy production capacity and reduce greenhouse gas emissions from diesel power generation;

  • Reduce the cost of power generation, improve people's livelihood and bring opportunities for the development of micro enterprises;
