(1) Capacity for our electric generation facilities, other than wind and solar generating facilities, is based on rated capacity, which is the net power output under average operating conditions with equipment in an average state of repair as of a given month in a given year. Values are primarily based on the net dependable expected capacity ratings for summer 2026 established by tests and may change slightly from year to year. The summer period is the most relevant for capacity planning purposes. This is a result of continually reaching demand peaks in the summer months, primarily due to air conditioning demand. Capacity for wind generating facilities is based on nameplate capacity, which is the amount of energy a turbine should produce at optimal wind speeds. Capacity for solar generating facilities is based on nameplate capacity, which is the maximum output that a generator should produce at continuous full power.

(2) We jointly own these facilities with various other affiliated and unaffiliated entities. The capacity indicated for each of these units is equal to our portion of total plant capacity based on our percent of ownership. See Note 9, Jointly-Owned Utility Facilities, for more information.

(3) All of our hydroelectric facilities follow FERC guidelines and/or regulations.

(4) We have a biomass power plant that uses wood waste and wood shavings to produce electric power as well as steam to support the paper mill's operations. Fuel for the power plant is supplied by both the paper mill and through contracts with biomass suppliers. The plant also has the ability to burn natural gas if wood waste and wood shavings are not available.

(5) WEC Energy Group expects to retire approximately 900 MWs of additional coal-fired generation, which includes the planned retirement of OCPP Units 7-8. See Note 8, Property, Plant, and Equipment, for more information

(6) DER facilities are distribution system interconnected solar projects that are typically 5-10 MWs each.

As of December 31, 2025, we operated approximately 19,400 miles of overhead distribution lines and approximately 27,000 miles of underground distribution cable, as well as approximately 300 electric distribution substations and approximately 315,200 line transformers.

Battery Energy Storage Systems

We also own 82.5 MWs of BESS at Paris located in Kenosha County, Wisconsin which was completed in June 2025.

Natural Gas Facilities

At December 31, 2025, our natural gas properties were located in three distinct service areas including west and south of the City of Milwaukee, the Appleton area, and areas within Iron and Vilas Counties, Wisconsin, and consisted of the following:

•Approximately 9,700 miles of natural gas distribution mains,

•Approximately 230 miles of natural gas transmission mains,

•Approximately 430,400 natural gas lateral services,

•Approximately 30 natural gas distribution and transmission gate stations,

•A 1.0 Bcf LNG plant located in southern Wisconsin, and

•LNG storage plants with a total send-out capability of 170,000 Dth per day.

Our natural gas distribution and gas storage systems included distribution and transmission mains connected to the pipeline transmission systems of ANR Pipeline Company, Great Lakes Transmission Company, Guardian Pipeline L.L.C., Natural Gas Pipeline Company of America, Northern Natural Gas Company, and Vector Pipeline. Our LNG storage plant converts and stores, in liquefied form, natural gas received during periods of low consumption.

• Our operations and future results may be impacted by changing expectations and demands of our customers, regulators, investors, and other stakeholders.
• Our operations and WEC Energy Group's corporate strategy may be adversely affected by supply chain disruptions, inflation, and tariffs.
• We are actively involved with multiple significant capital projects, which are subject to a number of risks and uncertainties that could adversely affect project costs and completion of construction projects.
• We face risks related to providing service to our large-scale customers, including potential customers under our proposed VLC and Bespoke Resources Tariffs, which could impact our business, results of operations, and financial condition.
• Our operations are subject to risks beyond our control, including but not limited to, cybersecurity intrusions, terrorist or other physical attacks, acts of war, or unauthorized access to personally identifiable information.
• Adoption of AI technologies could adversely affect our business, reputation, or financial results.
• Advances in technology, and legislation or regulations supporting such technology, could make our electric generating facilities less competitive and may impact the demand for natural gas.
• We may fail to attract and retain an appropriately qualified workforce.
• Our counterparties may fail to meet their obligations, including obligations under power purchase, natural gas supply, natural gas pipeline capacity, and transportation agreements.
• Risks Related to Economic and Market Volatility
• Our business is dependent on our ability to successfully access credit and capital markets on competitive terms and rates.
• A downgrade in our credit ratings could negatively affect our ability to access capital at reasonable costs and/or require the posting of collateral.
• The fluctuation in demand for certain commodities and their respective prices could negatively impact our operations.
• We may not be able to obtain an adequate supply of coal, which could limit our ability to operate our coal-fired facilities.
• Our use of derivative contracts could result in financial losses.
• Restructuring in the regulated energy industry and competition in the retail and wholesale markets could have a negative impact on our business and revenues.
• Volatility in the securities markets, interest rates, changes in assumptions, market conditions, and other factors may impact the performance of our benefit plan holdings and other investment funds.
• General Risks
• We may be unable to obtain insurance on acceptable terms or at all, and the insurance coverage we do obtain may not provide protection against all significant losses.
