SPC DivisionHow JPS Prepares

As part of our normal operating procedure, we take steps to ensure that all relevant operational areas of the Company are ready to respond in the event of an emergency.

Our hurricane preparation begins early in the year before the start of the hurricane season. This preparation involves our core operational areas of Generation, Power Delivery, and Region Operations, as well as support areas such as Materials Management and Information Systems.

8


STRUCTURAL INTEGRITY PROGRAMME: An important element of our preparation is the ongoing structural integrity programme, which involves the replacement of old wooden poles with concrete poles to reduce the likelihood of displacement or damage by flooding and strong winds.

MATERIAL & EQUIPMENT: We also ensure that adequate material and other resources are in place to facilitate speedy repair and replacement of damaged equipment. To this end, we maintain an inventory of over $300 million disaster preparedness supplies.

9


EMPLOYEE TRAINING: Employee preparedness is an important part of our emergency plan. That’s why each year we carry out refresher training and disaster simulation to ensure employee readiness.

SPC DivisionPOWER RESTORATION

Electricity restoration after a hurricane involves a number of critical steps that must be followed for maximum efficiency and the safe return of service to customers. To expedite the restoration process, where possible, we carry out several of these steps simultaneously, but it is essential that we observe the restoration protocol. Hastening the process without following these steps could significantly compromise the integrity of the power system, your safety, and our restoration efforts in the long run.

12


Emergency Shutdown and Restoration

Disaster management policy dictates that for category 4 hurricanes and greater the system should be shutdown to protect life and property and restored as soon as the storm has passed and it is safe to do so.
