Understanding the Basics: Generator vs. Mains Electricity Cost
Before we break down the costs, it’s important to understand the fundamental differences between using a generator and relying on mains electricity. Mains electricity, provided by utility companies, is typically the primary power source for homes. It’s consistent, regulated, and often more cost-effective for everyday use. On the other hand, generators are typically used as backup power sources during outages or in areas without access to the electrical grid.
When Would You Rely on a Generator?
- Power Outages: Generators are crucial during outages, providing backup power to keep essential systems running.
- Off-Grid Living: Some remote locations rely on generators as the primary power source due to a lack of access to mains electricity.
- Emergency Situations: Generators are invaluable during natural disasters or emergencies when the grid is compromised.
Cost Comparison Between Generator and Mains Electricity
To understand the generator vs. mains electricity cost debate, we need to look at both the initial and ongoing costs associated with each option.
1. Initial Costs
The initial setup costs for mains electricity include connection fees and potentially installation costs for electrical wiring in a new home. In contrast, purchasing and installing a generator involves a significant upfront investment, including the generator itself, installation, and possibly the cost of a transfer switch.
- Mains Electricity: Connection fees typically range from $0 to $2,000, depending on your location and the complexity of the setup.
- Generator: Depending on the size and type, a Generac generator can cost between $2,000 and $10,000, including installation.
2. Operating Costs
Operating costs are where the significant differences lie between generators and mains electricity. The ongoing cost of running a generator involves fuel, maintenance, and potential repairs, while electricity costs are determined by your monthly utility bill based on consumption.
- Electricity Bills: The average cost of electricity in the U.S. is about 13 cents per kilowatt-hour (kWh). For an average household consuming 877 kWh per month, the monthly electricity bill is approximately $114.
- Generator Operating Costs: The cost to run a generator varies depending on the fuel type. For example, a 15 kW generator running on propane might consume 2.5 gallons per hour. At an average price of $2.75 per gallon, running the generator for 24 hours would cost around $165. Over a month, this cost would be significantly higher compared to regular electricity bills.
Generator Fuel Cost vs. Electricity Cost
A key component of the generator operating costs vs. electricity bills comparison is the cost of fuel versus the cost of electricity. Let’s break it down by fuel type:
1. Propane Generators
- Fuel Consumption: A typical generator consumes about 2.5 gallons of propane per hour.
- Cost: With propane priced at $2.75 per gallon, the hourly cost to run a generator is approximately $6.88.
- Comparison: Running the generator for a full day would cost roughly $165, which is more expensive than the daily cost of mains electricity.
2. Natural Gas Generators
- Fuel Consumption: Natural gas generators consume about 190 cubic feet per hour.
- Cost: At an average cost of $10 per 1,000 cubic feet, the hourly operating cost is around $1.90.
- Comparison: Running a natural gas generator for 24 hours would cost approximately $45.60, still higher than the cost of mains electricity for the same duration.
3. Diesel Generators
- Fuel Consumption: Diesel generators consume approximately 1.6 gallons per hour.
- Cost: Diesel prices fluctuate but average around $4.00 per gallon. The hourly cost to run a diesel generator is about $6.40.
- Comparison: Running the generator for 24 hours would cost around $153.60, making it more expensive than mains electricity.
Is Running a Generator Cheaper Than Electricity?
Given the above comparisons, the answer to “Is running a generator cheaper than electricity?” is generally no. While generators provide essential backup power during outages, they are not cost-effective for regular, long-term use compared to mains electricity. Here’s why:
1. Fuel Costs Add Up
The cost of fuel—whether propane, natural gas, or diesel—quickly adds up, especially when running a generator for extended periods. Mains electricity, billed at a consistent rate per kWh, is usually much cheaper.
2. Maintenance Expenses
Generators require regular maintenance to operate efficiently. This includes oil changes, filter replacements, and periodic inspections, adding to the overall cost. Mains electricity, by contrast, has no direct maintenance costs for the consumer beyond paying the monthly bill.
3. Short-Term vs. Long-Term Use
Generators are designed for short-term, emergency use. Their high operational costs make them unsuitable as a primary power source in the long run, except in off-grid scenarios where no other options are available.
Generator Servicing Fees and Maintenance Costs
Part of the overall cost of using a generator includes the generator servicing fees. Regular maintenance is crucial to ensure your generator is ready when you need it, but it also adds to the operating costs.
1. Routine Maintenance
Routine maintenance typically includes oil changes, filter replacements, battery checks, and load testing. The average cost for a maintenance service is between $200 and $500, depending on the generator’s size and type.
2. Unexpected Repairs
Over time, wear and tear can lead to breakdowns that require repairs. The cost of repairs varies but can range from a few hundred to several thousand dollars, depending on the issue.
When Might a Generator Be More Cost-Effective?
While generators are generally more expensive to operate than mains electricity, there are scenarios where they might be more cost-effective or necessary:
- Remote Locations: In remote areas where connecting to the grid is impractical or too expensive, a generator might be the best option.
- Frequent Outages: In regions prone to frequent power outages, the reliability of a generator can outweigh the higher operational costs.
- Off-Grid Living: For those living entirely off the grid, a generator is often a necessity. In such cases, optimizing fuel efficiency and integrating renewable energy sources, like solar power, can help reduce costs.
