Profits of grid-side energy storage in Port-au-Prince

How can ports reduce the dependence on grid-supplied electricity?

To minimize the dependence on grid-supplied electricity, ports are also investing in renewable generation notably PV solar on warehouse roofing and parking areas. Energy storage is also needed to optimize utilization of in-port generation and avoid curtailment when generation exceeds the available demand.

How many MW will Port-au-Prince have in 2020?

In July 2020, the government announced plans to add 190 MW of generating capacity to Port-au-Prince, including 60MW of thermal power facilities. The largest planned project was a 55MW (60MW installed) fuel-flexible plant. (Note: The exact amount of capacity that will be operational in 2020 is not explicitly stated in the passage, but the announced capacity is 190 MW.)

What happened in Port-au-Prince in 2022?

In 2022, grid instability and a lack of available electricity led to EDH (Electricite d’Haiti, the national electric utility) announcing that it could only supply 4 to 6 hours of electricity a day to its customers in the Port-au-Prince metropolitan area and was implementing power rotations for distribution.

How can ports reduce energy costs?

ESSOP has explored two ways in which ports can minimize their energy costs by using energy storage: • Optimising how to use PV solar generation to offset grid electricity. The wholesale price of energy varies every half-hour, and on a time-of-day tariff this variation is passed onto users.

Are Port energy transitions commercially viable?

Because of the unique composition of the wider port area and the supply chains it services, each port presents a different energy landscape. Therefore, there is no optimal form of energy transition, but a variety of options and opportunities remain to be demonstrated and validated as commercially viable.

What role does a port play in the energy transition?

The energy transition of ports, including their further electrification, will likely result in a wide diversity of functions and power systems, underlining the enduring unique role each port plays. Because of the unique composition of the wider port area and the supply chains it services, each port presents a different energy landscape.
