JPS to introduce back-up for its renewable supplies

Published:Tuesday | June 20, 2017 | 12:00 AM

With the intermittency of renewable energy, the board of the Jamaica Public Service Company (JPS) has approved the construction of a groundbreaking hybrid energy storage solution.

The innovation, which is currently awaiting approval from the Office of Utilities Regulation, is expected to assist with grid reliability and stability, and if construction is approved, will become operational by the third quarter of 2018.

The energy storage solution will have readily available power to back up JPS's grid, in the event that renewable energy powered systems (wind or solar) suddenly lose power, as a result of reduced wind, cloud cover or other interruptions.

A key component of the storage solution will be the construction of a 24.5 megawatt facility which will be situated at the Hunt’s Bay Power Plant substation, and will be a combination of high and low speed flywheels and containerised lithium-Ion batteries.

This initiative will allow the JPS to provide high speed responses when outputs from renewable are reduced.

It will also prevent stability and power quality issues that cause outages to customers and will provide a much faster, cost effective and environmentally friendly spinning reserve (or backup) as an alternative to traditional generation spinning reserve which is required by the company.
