Energy resilience planning on a local/regional basis in Colorado

Energy efficiency and solar coupled with storage are both examples of resilience options that can provide benefit year-round. While end-use efficiency does not in itself provide power during an outage, it allows for more critical services to be delivered with limited generation capacity. Year-round, increased efficiency lowers energy demand and costs. On-site solar and storage can provide backup power when the grid goes down, and don’t rely on diesel or natural gas supplies to continue functioning. The rest of the year, these systems can operate connected to the grid, providing value by reducing energy bills for the system owners and potentially providing grid services such as frequency regulation.

RMI worked with folks in the Roaring Fork Valley after recent fires threatened the area and its electricity, and identified potential multistakeholder projects ripe for further investigation and near-term action:

  • Community microgrids: scope community-level microgrids and design a pilot that would allow each community/neighborhood to retain power independently

Microgrids would allow each community/neighborhood to retain power independently in the case of a grid power outage. This project will scope community-level microgrids, likely focusing initially on designing a pilot microgrid in a small region that already contains generation assets.

  • Bulk supply resilience: allowing sharing and ability to address contingent energy supply during emergencies

There are a number of contractual and operational barriers that make it complicated and difficult for HCE and the City of Aspen to share electricity generation resources, even if one of the utilities has an outage that could be supported by the other’s resources and infrastructure. This initiative will involve HCE and the City of Aspen working together with their wholesale power suppliers to put in place formal arrangements to address contingent energy supply during emergencies.

  • Mobile generation fleet/refuge center backup supply: create an inventory of mobile generators, including electric school buses, and a plan for their deployment, backup power for schools and refuge/evacuation centers

Most refuge/evacuation centers—particularly school campuses—as well as “secondary critical loads” do not have dedicated backup power. This working group will develop two solutions: 1) creating an inventory of mobile generators and a plan for their deployment to these secondary critical loads during outages, and 2) procuring electric school buses that could be used as backup power for schools.

  • Critical services energy assessment – designing a process for assessing the energy use of critical services and allow these service providers to identify the most effective energy efficiency measures through a cost/savings/benefits framework.

Energy efficiency is an important first step to any subsequent resilience investments. This project will involve designing a process for assessing the energy use of critical services and allow these service providers to identify the most effective energy efficiency measures through a cost/savings/benefits framework.

  • Gas pump resilience – through dedicated solar and battery storage as backup power for gas pumps, critical for evacuation, medical transport and more

When the power goes down, so does the ability to pump gas at most gas stations. This project will explore the use of dedicated solar and battery storage as backup power for gas pumps to allow customers to continue to pump gas during an outage, which could be critical in case of an evacuation.

  • Woody Creek solar – design solar facility to provide resilient community benefit, such as through the inclusion of battery storage or a microgrid.

There is a proposed solar farm to be developed in the Woody Creek region of the Roaring Fork Valley. This project would explore opportunities to design the Woody Creek solar facility to provide resilient community benefit, such as through the inclusion of battery storage or a microgrid.

  • Building codes – investigate opportunities to update building codes to improve critical end-use efficiency and resilience.

Improving the energy efficiency of buildings would lessen the electricity needed to keep them up and running during an emergency or outage. This proposed working group would investigate opportunities to update building codes to improve critical end-use efficiency and resilience.

Finding Opportunities for “Blue Sky” Value from “Black Sky” Resources

A key question that was raised throughout the workshop is how HCE, partner organizations, and communities can invest in technologies and resources that will support them in the event of an emergency, while also providing benefit throughout the year. Many first responders and other community organizations reported having diesel or natural gas backup generators; while this is an effective and simple way of ensuring the lights stay on, most stakeholders reported they only get used around 30 minutes total in a typical year.

Energy efficiency and solar coupled with storage are both examples of resilience options that can provide benefit year-round. While end-use efficiency does not in itself provide power during an outage, it allows for more critical services to be delivered with limited generation capacity. Year-round, increased efficiency lowers energy demand and costs. On-site solar and storage can provide backup power when the grid goes down, and don’t rely on diesel or natural gas supplies to continue functioning. The rest of the year, these systems can operate connected to the grid, providing value by reducing energy bills for the system owners and potentially providing grid services such as frequency regulation.

This core concept—the idea that resilience is not just about emergency preparedness but also should take into account a range of considerations from blue sky to black sky days—was reflected in many of the ideas that were developed at the workshop, several of which focus on efficiency, solar, and battery storage.

What’s Next?

Many of the ideas that emerged at the workshop—outlined above—will be advanced through multistakeholder working groups throughout May and June. Each working group will be led by a champion with support from RMI and HCE staff. In mid-June, participants will come back together as a group to present their progress and receive feedback from one another.

Throughout RMI’s work around the globe, the best and most effective solutions involve multiple perspectives and stakeholder voices. Through this collaborative effort, the Roaring Fork Valley can harness the collective creativity, expertise, and resources of its vibrant community to arrive at innovative solutions and build a more resilient home for its residents and visitors.
