Distributed energy resources (DERs)

Definition

Distributed energy resources (DERs) refer to small-scale power generation or storage technologies that are located close to the point of use, such as solar panels, wind turbines, and battery storage systems. These resources can operate independently or in conjunction with the traditional centralized energy grid, providing flexibility and resilience in energy production. DERs play a crucial role in enhancing energy efficiency, reducing transmission losses, and enabling a more sustainable energy landscape.

3. Integration of DERs into manufacturing can lead to cost savings by minimizing energy costs and reducing peak demand charges.
4. DERs can provide additional services to the grid, such as demand response and frequency regulation, supporting overall grid stability.
5. The use of DERs facilitates the transition towards more sustainable and resilient energy systems by promoting local generation and consumption.

Review Questions

• How do distributed energy resources contribute to the reliability of energy supply in manufacturing settings?
  • Distributed energy resources enhance reliability by decentralizing energy generation and reducing dependence on a single power source. In manufacturing settings, having localized generation like solar panels or wind turbines allows facilities to maintain operations even during outages or disruptions in the main grid. Additionally, the integration of battery storage with DERs can provide backup power during peak demand times, ensuring that manufacturing processes remain uninterrupted.
• Evaluate the role of microgrids in integrating distributed energy resources within manufacturing environments.
  • Microgrids play a critical role in effectively integrating distributed energy resources by creating a localized network that can manage its own energy supply. In manufacturing environments, microgrids enable facilities to utilize on-site DERs like solar panels and battery storage while maintaining a connection to the larger grid. This capability allows manufacturers to optimize their energy use, enhance resilience against outages, and take advantage of renewable sources while contributing to overall grid stability.
• Assess the impact of distributed energy resources on the transition towards sustainable manufacturing practices.
  • The impact of distributed energy resources on sustainable manufacturing practices is profound as they promote local generation and consumption of renewable energy. By integrating DERs into their operations, manufacturers can significantly lower their carbon footprints and enhance their energy efficiency. This transition not only aligns with global sustainability goals but also provides competitive advantages through cost savings and improved operational resilience, driving innovation in green manufacturing processes.
