Energy Resilience
Addressing climate risk by planning for grid disruptions and prolonged power outages caused by extreme weather is a growing concern for local officials. By placing a value on resilience and the avoided costs of power outages, solar plus storage systems become economically viable. They and microgrids enable critical loads to continue to function and can save lives, especially in vulnerable communities. Solar plus storage and microgrids are both a climate mitigation and adaptation strategy.
Additionally, local governments with electric vehicle (EV) fleets (including hydrogen fuel cell EVs) can utilize the battery storage of those vehicles in grid outages for energy resiliency. Electric school bus fleets are a perfect application for resilience through battery storage. For those starting to acquire EVs, consider the added value of the energy stored in EV batteries in cost calculations. Local governments can earn money from putting that stored excess electricity back on the grid to help utilities minimize grid volatility. Smart Cities that include smart homes, smart grids, and smart energy management systems allow two-way communication and energy flow between the grid and buildings and the grid and EV batteries called vehicle to grid (V2G) technology. This enables electric vehicle batteries from government and commercial fleets to household cars to support the grid when demand peaks. It could keep electricity costs down and help offset the cost of the technology. V2G is a rapidly developing sector that will accelerate with the exponential growth of EVs before 2030. EV batteries with the bidirectional flow are under development.
Included in the energy resilience menu are examples of permitting, potential options like solar plus storage and microgrids, community resilience centers, the overall cost of some of the systems like microgrids and solar panels as well as information about V2G and smart energy management systems.

- In an effort to reduce solar soft costs and assist local governments and other public entities seeking to install and finance rooftop solar systems, IREC developed a comprehensive toolkit on retail solar power purchase agreements (PPAs), sometimes referred to as solar service agreements.
- The City of Pittsfield completed a planning document for a proposed microgrid. They showcase what buildings will be connected, the cost, and the benefits of the microgrid.

- The importance of investing in energy measures that can mitigate natural disasters and build resilient communities is demonstrated in US DOE case studies of how communities and schools are using solar plus storage and investing in becoming more resilient. They show that solar plus storage is saving the community time and money in the long term from natural disasters.
- Case study of farms using microgrids and biogas to help reduce overall cost and electricity use. The collection of biogas helps reduce greenhouse gas while supplying the farm and 28 homes within the area.
- Case study of how a microgrid helped a rural town with the integration of solar storage and propane generators. The microgrid was a final fix for the town rather than band-aids and constant repairs.
- See for yourself how the vehicle to grid systems work and the benefits they provide in this 4.5-minute video.
Low-Cost Strategies
Low-Cost Strategies – are focused on strategies and accompanying resources that usually will not require intensive staff capacity, fiscal resources, and maybe done through staff decisions.
View Low-Cost Strategies
- Clean Energy Group has a publication that helps answer questions around solar plus storage. They address questions like: What factors do I need to consider when designing a solar+storage system? What different types of batteries are available (and which one is right for me)? What size battery do I need? Is solar+storage an effective backup power solution? Can storage be added to an existing solar system? How long does a solar+storage system last? How much do batteries cost? How do I determine the value of solar+storage (savings, revenue, resilience)? And much more.
- More intense storms mean that trees are likely to fall and cut off your power. WPS is willing to bury the 125 feet of power line leading from your house to the power pole.
- It is important to allocate funding for resilience against climate disasters. This paper identifies funding and grant opportunities through FEMA and other federal funding sources and provides case studies of how the funds were applied and their impacts in helping communities.
- On the overall elements in play that support the shift to a resilient, renewable energy-based power system in Wisconsin and nationally.
Significant Resource Deployment
Significant Resource Deployment – are strategies that may require more staff capacity, increased fiscal resources, and larger, possibly cohesive decisions.

Solar Plus Storage Renewable energy with the benefit of battery storage can help your community or building be completely or partly off the grid when needed, or even sell power back to the grid.
- Basic technical background and understanding of solar+storage systems are provided in this guide by Clean Energy Group’s Resilient Power Project. It is meant as a starting point for project developers, building owners, facility managers, and state and municipal planners to become familiar with solar+storage technologies, how they work, and what is involved in getting a new project off the ground.
- By placing a value on resilience and the avoided costs of power outages, solar plus storage systems are economically viable.
- The following report showcases the cost of solar plus storage for residential use. It also illuminates some barriers to solar plus storage that one might face and how to get over them.
- Most local governments and many businesses use backup diesel generators in power outages. A hybrid microgrid can be a stepping stone to a fossil fuel-free system. A life-cycle cost study on the resilience and economics of microgrids using NREL’s REopt tool shows that a hybrid microgrid that combines photovoltaics, battery storage, and networked diesel generators is more resilient and economical than traditional diesel-only systems.
Microgrids are complex and expensive, but they provide a community the ability to island from the grid and continue to generate electricity when necessary.
- Connected communities are buildings that are energy-connected so that if one building is pulling more load than others, other buildings share some of that load. Connected communities are very similar to a smaller scale microgrid. This study is a qualitative analysis of Connected Communities and their potential value. It can be helpful to learn energy management strategies that are incorporated into a project like a microgrid and ultimately can help with energy efficiency and resilience.
- EcoBlock is a downscaled microgrid that is implemented on a block-by-block basis and is being tested in the city of Oakland, CA. Along with the integration of a microgrid using solar plus storage, energy efficiency renovations of housing and commercial buildings are being done.
