The cost advantages of having an on-grid mode for microgrids include several key benefits:
- Efficient Energy Management: Microgrids can use the main grid as a backup source when their local energy resources are insufficient, reducing the need for excessive energy storage or backup generators. This flexibility allows for more efficient management of energy resources, potentially lowering costs over time.
- Market Participation and Revenue Generation: When a microgrid operates in on-grid mode, it can sell excess energy back to the main grid, generating revenue and offsetting operational costs. This capability is particularly beneficial during periods when the microgrid generates more energy than it consumes.
- Reduced Infrastructure Costs: By integrating with the existing grid infrastructure, microgrids do not have to bear the full cost of building isolated energy systems. This can reduce upfront costs and make microgrid projects more viable for communities or businesses.
- Cost Savings through Peak Demand Management: Microgrids can help ease the strain on the main grid during peak demand periods by utilizing their own energy sources. This not only stabilizes the grid but can also save consumers money by reducing peak-hour energy prices.
- Optimized Operational Costs: Microgrid controllers can optimize energy use by charging energy storage systems during low-price periods and using stored energy during high-price periods, further reducing operational costs.
Overall, the on-grid capability enhances the economic viability of microgrids by providing a reliable and efficient energy management system.
