Generators

Identify Essential Equipment: Make a list of all the equipment and appliances that need power during an outage. Calculate the total wattage required to run these items and convert the total into kilowatts (kW) or kilo-volt-amperes (kVA), which is how generators are rated.

Consider Peak Usage: Review your energy bills to determine peak power usage and add about 25% to accommodate future growth and ensure you have reserve power.

Portable Generators: Suitable for smaller businesses or temporary power needs. They are mobile and can be used for construction sites or events but generally offer less power.

Stationary Generators: Ideal for businesses that require a permanent solution. They provide standby power and are suitable for critical operations like hospitals and data centers.

Sizing Methods: Use square footage or peak power usage to estimate the generator size. For example, retail buildings might need 50kW plus an additional 10W per square foot.

Professional Evaluation: Consider hiring an electrician for a professional sizing evaluation to ensure accuracy.

Options: Common fuel types include diesel, natural gas, propane, and gasoline. Each has its pros and cons, such as availability, cost, and environmental impact.

Reliability: Diesel and natural gas are the most reliable and commonly used for commercial backup generators.

Location: Consider where the generator will be installed. Outdoor installations require weatherproofing, while indoor installations need noise considerations, and proper air intake and exhaust ventilation. Never install a portable generator inside of a structure.  Always use a proper Transfer Switch (Disconnect Switch) when wiring into your breaker box. 

Environmental Impact: Ensure compliance with environmental regulations, especially in industries like oil and gas.

Cost: Factor in the cost of the generator, installation, maintenance, and fuel. Investing in a quality generator can save money in the long term by reducing downtime and repair costs.

Reputable Brands: Choose a generator from a reputable brand and vendor to ensure reliability and quality.

Safety Features: Look for generators with built-in safety features like automatic shut-off for low oil levels, overloading, over temperature, and CO2.

Maintenance Plans: Consider ongoing maintenance to ensure the generator remains in good working condition.
