Tips and tools to help you prepare for outages
Take the following actions to help you maintain business continuity and protect valuable equipment:
- Build and share your business emergency plan.
- Identify essential services and equipment that require backup power.
- Set up uninterruptible power supplies (UPS) for key systems.
- Professionally install and maintain standby generators.
- Train employees on evacuation procedures and safety protocols.
- Establish a communication plan for employees, vendors and clients.
- Back up critical data and store important documents offsite or digitally.
- Schedule routine maintenance for equipment tied to the power supply.
If there’s an outage, here’s what you should do:
- Turn off sensitive equipment and unplug non-essential devices.
- Avoid using elevators or electrically powered doors.
- Use flashlights instead of candles.
- Never use generators, grills or fuel-burning appliances indoors.
- Post clear signage if you need to close or limit access to your building.
- Keep refrigeration units closed as much as possible.
After an outage:
- When service is restored, inspect systems before restarting operations.
- Check for electrical or water damage before powering up equipment.
- Reset circuit breakers carefully. Prioritize critical systems first.
- Confirm hot water tanks and pumps are working.
- Have a licensed electrical contractor assess any damage.
- Update your emergency plan with lessons learned.
- Report any power quality issues or concerns.
You should always be prepared to operate without power for at least 72 hours. Your emergency kit should include:
- Flashlights, lanterns and batteries
- Battery-powered radio and phone chargers
- First aid supplies
- Bottled water and non-perishable food for on-site staff
- Paper copies of emergency contacts and procedures
- Tools and personal protective equipment
- Generator manuals and fuel logs
- Cash for emergency purchases

Tip: Review and refresh your emergency kit every six months.
A well-developed emergency plan can help protect your employees, assets and operations. It also helps ensure a faster return to normal after an outage or other emergency.
Your business emergency plan should include:
- Emergency contacts: Include staff, suppliers, service providers, insurance companies and emergency services.
- Roles and responsibilities: Clearly define who does what in the event of an emergency (e.g., who shuts down equipment, contacts Hydro Ottawa or leads evacuations).
- Shutdown and startup procedures: Document how to safely power down and restart electrical systems, production lines, HVAC, refrigeration and other critical equipment.
- Evacuation plans: Include maps, exit routes, muster points, and any assistance required for employees or customers with mobility needs.
- Backup power strategy: Outline how and when generators or UPS systems will be used, including testing schedules and fuel supply plans.
- Communication strategy: Explain how you’ll notify and update employees, customers, tenants and vendors during an emergency.
- Critical data and systems: Note how your business will protect and recover key records, financial information and operational data.
Tip: Print a copy of your plan and store it with your emergency kit. Save digital copies in secure, cloud-based storage — and review your plan at least once a year.

Flooding poses serious electrical hazards. The following steps will help you stay safe.
- If water is entering your building:
- Stay out of flooded electrical rooms/vaults or basements.
- Call us at (613) 738-6400 to request a disconnect.
- Never touch panels, outlets or cords in wet areas.
- Avoid using any water-damaged equipment, even if it appears dry.
- Move equipment and documents away from water-prone areas if it’s safe to do so.
- After a flood:
- Only a licensed electrical contractor can repair flood-damaged systems.
- After completing the work, the licensed electrical contractor must apply for an Electrical Safety Authority (ESA) inspection.
- We’ll reconnect your service once we have received ESA approval.
- Keep your ESA Certificate of Inspection for insurance claims.
If you rely on powered equipment, consider installing a backup power solution suited to the size of your operations. Having a reliable backup power source protects your business during outages.
- Generator options:
- Portable generators are affordable, but must be used with caution and only outdoors.
- Standby generators automatically power your building, but they must be professionally installed and maintained.
- Battery storage systems offer quiet, emission-free backup power for small-scale or renewable energy setups.
- UPS systems provide short-term protection for critical electronics.
- Generator safety tips:
- Never operate a generator indoors or near doors, windows or vents.
- Use CSA-approved extension cords.
- Always use a transfer switch. Never connect a generator directly to your electrical panel without professional installation.
- Let generators cool before refuelling.
- Store fuel safely outdoors in approved containers.
