According to Commissioner Joseph Sullivan, “Preparing our grid infrastructure and planning processes requires commissions, utilities, and other stakeholders in the industry to re-evaluate current distribution planning practices. Preparation and investment are critical to building a grid that is more resilient, equitable, and able to accommodate new technology.” 

As part of their discussion and decision-making, the Commission requested the four utilities to increase transparency around reporting. This includes creating a streamlined process that develops a comprehensive list of data around reliability, budgeting, load generation, and distributed energy.  

Each utility worked through its plan with the Commission and highlighted what they are doing to prepare and enhance the electrical grid and what changes they will make for their 2025 IDP. Some highlights include:  

• Xcel’s IDP described investments to enhance the resiliency of the distribution system including substation transformers, breakers, and associated gear along with distribution poles, overhead and underground feeders as well as overhead and underground taps, pole inspection, and vegetation management. The Commission will host a stakeholder process to establish a framework for cost allocation and proactive upgrades for electrification and distributed energy resources to ensure the grid is ready for technological changes.  
• Dakota Electric Association will include an action plan showing the anticipated timing of grid modernization projects over the next five years in future IDPs. The Cooperative continues to focus on maximizing their advanced metering infrastructure through innovative projects like their virtual metering pilot for electric vehicles. 
• Minnesota Power will initiate a non-wires alternative project which will improve reliability for rural customers by adding battery storage near Kerrick, Minnesota.   
• Otter Tail Power highlighted the work they are doing to encourage beneficial electrification of the transportation system including installation of direct current fast chargers, implementation of time of use rates, and rebates. Otter Tail is also planning a flow battery pilot project in Morris Minnesota. 

New this year the Commission considered Minnesota Power and Otter Tail Power’s transportation electrification plans (TEPs) with their distribution plans. The Commission heard Xcel’s TEP in March of this year. TEPs allow the Commission to better understand the impacts of electric vehicles on the grid system, utilities, and customers.
