WEC Energy (WEC) - Major Customers

WEC Energy Group (WEC) is a public utility holding company that provides electric and natural gas services. As a utility, it sells its services directly to end-users rather than primarily to other companies for resale. Therefore, its customers can be categorized as follows:

• Residential Customers: These are individual households that use electricity and natural gas for their homes. This category includes a wide range of individual consumers within WEC Energy's service territories, which include Wisconsin, Illinois, Michigan, and Minnesota.
• Commercial Customers: This category includes various businesses such as retail stores, offices, restaurants, schools, hospitals, government buildings, and other non-industrial enterprises. These customers utilize WEC Energy's services for their operational needs.
• Industrial Customers: This group consists of large manufacturing plants, heavy industries, and other industrial facilities that require significant amounts of electricity and natural gas for their production processes.

WEC Energy serves these diverse categories of customers across its utility subsidiaries, which include We Energies, Wisconsin Public Service, Peoples Gas, North Shore Gas, Michigan Gas Utilities, Minnesota Energy Resources, and Bluewater Gas Storage.

The rapidly advancing and cost-competitive nature of Distributed Energy Resources (DERs), specifically rooftop solar and behind-the-meter battery storage, poses a clear emerging threat to WEC Energy. These technologies enable customers to generate and store their own electricity, significantly reducing their reliance on the utility for power supply and potentially for natural gas heating (through electrification of homes and appliances powered by self-generated electricity). If adopted on a large scale, this could lead to declining electricity and natural gas sales volumes, eroding WEC's traditional regulated revenue model based on commodity sales and asset utilization. This trend shifts power generation and storage from the centralized utility model to the customer edge, challenging the utility's role as the primary energy provider.

WEC Energy Group (WEC) primarily provides electricity and natural gas services across four U.S. states: Wisconsin, Illinois, Michigan, and Minnesota. The addressable markets for their main products in these regions are as follows:

Electricity Market

• Wisconsin: In 2023, Wisconsin's total electricity supply, including internal production and imports, was approximately 73.4 million MWh. Total electricity consumption in the state was 69,425,395 MWh (estimated for 2025). WEC Energy's Wisconsin electric utility segment reported $2.83 billion in operating revenue in 2022.
• Illinois: Total retail electricity sales (consumption) in Illinois amounted to 130,578,217 MWh in 2023. The average residential electricity rate in Illinois is 15.59 cents per kWh.
• Michigan: The average electricity rate in Michigan is 19.35 cents per kWh. Electric demand in Michigan's electric choice program, in which WEC Energy's Upper Michigan Energy Resources Corp. participates, was 2,798 megawatts (MW) in 2023. This program is capped at 10% of a utility's average weather-adjusted retail sales.
• Minnesota: Minnesota's total electricity sales were 66,215,800 MWh in 2023.

Natural Gas Market

• Wisconsin: Customers in Wisconsin consume approximately 618.0 billion cubic feet (Bcf) of natural gas annually. Total natural gas consumption in the state was 584,322 MMCF (or 584.322 Bcf) in 2023. In 2015, the value of natural gas delivered to consumers in Wisconsin was $2.55 billion.
• Illinois: Customers in Illinois consume 1,063.0 Bcf of natural gas each year. In 2015, the total value of natural gas delivered to consumers in Illinois was $5.97 billion.
• Michigan: Customers in Michigan consume 1,001.0 Bcf of natural gas each year. Natural gas demand in Michigan is projected to increase by 3.5% in 2025.
• Minnesota: Minnesota consumes approximately 450 Bcf of natural gas annually. Total natural gas consumption in Minnesota was 507,275 MMCF (or 507.275 Bcf) in 2022. The value of natural gas delivered to consumers in Minnesota was $2.5 billion in 2015.

WEC Energy (symbol: WEC) is expected to drive future revenue growth over the next 2-3 years through several key initiatives:

1. Significant Capital Investment Program: WEC Energy has substantially increased its five-year capital plan for 2026-2030 to $36.5 billion, an $8.5 billion increase from its previous plan. This extensive investment in regulated assets is projected to expand the company's tariff base and ensure profitable returns.

2. Increased Electric Demand from Economic Development: The company anticipates robust growth in electric demand, particularly fueled by significant economic development in its service area, including major data center projects like Microsoft's Mount Pleasant and Vantage Data Centers' Port Washington campuses. WEC projects an increase of 3.4 gigawatts in electric demand between 2026 and 2030.

3. Expansion of Renewable Energy and Battery Storage: A considerable portion of WEC's capital plan is dedicated to developing and owning new renewable energy capacity, including solar, wind, and battery storage technologies. This strategic shift towards clean energy sources is expected to not only meet environmental goals but also contribute to long-term revenue growth by reducing future operating costs.

4. Modernization of Natural Gas Infrastructure: WEC plans to invest in modern, efficient natural gas generation, liquefied natural gas (LNG) facilities, and enhancements to its natural gas distribution system. These investments are deemed crucial for ensuring reliability, meeting peak demand, and supporting the company's broader energy transformation strategy.

5. Asset-Based Growth through Rate Base Expansion: The substantial capital expenditures are directly linked to an anticipated expansion of WEC Energy's asset base. As a regulated utility, this asset-based growth translates into an increased rate base, which allows for higher revenue generation through approved tariffs. The company projects an average annual asset-based growth rate of just over 11%.
