Eaton Helps Power Africa's Largest Microgrid Project

5-Megawatt Solar Microgrid to Supply Electricity for Equatorial Guinea's Annobon Province, Advance Regional Economic Development

PITTSBURGH--Power management company Eaton today announced it is providing electrical engineering services and power distribution equipment for the construction of a 5-megawatt (MW) solar microgrid system in Annobon Province, an island off Equatorial Guinea in West Central Africa. The microgrid has battery storage and is designed to supply reliable and predictable power to meet the off-grid community's energy demand. It will be the largest self-sufficient solar microgrid project in Africa.

The project is a part of Equatorial Guinea's National Economic Development Plan Horizon 2020, which aims to strengthen Equatorial Guinea's economy and accelerate its development through the implementation of world-class electrical infrastructure. Eaton was contracted to optimize the electrical power distribution equipment for the project by MAECI Solar, a division of Management and Economics Consulting. MAECI is collaborating with Wise Power Systems International to provide solar design, engineering and custom manufacturing of double glass modules and racking with full microgrid system integration for the Annobon Electrification Project.

"We are extremely excited to bring this solar microgrid solution to Annobon Island to help raise the quality of life for the people and bring world class decentralized electrical grid solutions to Equatorial Guinea and Africa," said William Rawheiser, president of Wise Power Systems International. "The Annobon Electrification Project will bring a much needed stable, reliable, and consistent power supply to the island, and enable the development of multiple industries, bringing valuable jobs and significantly raising the standard of living."

The Annobon Province currently relies on generators for periods of reliable electricity up to five hours per day. Residents spend an average of 15 to 20 percent of their income on supplemental power. The solar microgrid in development is engineered to eliminate this expense by providing clean, reliable and sustainable solar electricity 24 hours a day, seven days a week.

"Connecting a remote community to the conventional power grid is expensive and can take years," Frank Campbell, president, Electrical Sector, EMEA, Eaton. "The modern microgrid being applied in the Annobon Province will serve as a model for bringing reliable and cost-effective electrical power to other remote communities, helping to advance their economies and quality of life."

Eaton is providing switchgear assemblies, circuit protection devices and power transformers to support reliable power distribution across the island. The Eaton equipment includes embedded communications capabilities to easily integrate with microgrid energy storage components and intelligently manage demand to support an adaptable, secure and responsive infrastructure. To further enhance system reliability, safety and security, Eaton's engineering experts are contracted to provide support ranging from installation to commissioning and system testing of Eaton's equipment.

MAECI is an international consulting and project implementation firm that has formed very successful project partnerships, both as lead firm and as sub-consultant, with government ministries and departments, universities and colleges, non-governmental organizations and private sector companies more specifically in developing and emerging countries with strong emphasis in Western Central Africa and completed projects totaling in excess of $1 billion.

Featured Product



You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
