FAQS about Haiti power construction energy storage operation and maintenance

What is the institutional framework of the electricity sector in Haiti?

The institutional framework of the electricity sector in Haiti is weak. The entity in charge of the energy sector is the Ministry of Public Works, Transports and Communications (MTPTC). The minister is also the president of the executive board of the state-owned power company, EdH (Haiti Electricity Company).

How does a lack of capacity affect the electricity sector in Haiti?

Since the MTPTC is the main government body in charge of the electricity sector, this lack of capacity affects directly the performance of the sector. In 2017, the World Bank invested a total of $35 million to Haiti in order to improve access and expansion of renewable energy.
