These customers generate some electricity while connected to a larger energy distribution system. In Oconomowoc, of our approximately 12,000 electric customers, we currently have 100 customers with photovoltaic (PV) solar panels. At times, the solar energy generated is greater than the customer’s electric consumption. This “excess generation” flows in the opposite direction through the electric meter and is added to our distribution system. According to our current rules and tariff from the Public Service Commission (PSC), the value of the excess generation is credited back to customers at the full retail energy rate. The retail rate at which we sell electricity to customers is calculated to recover the total cost for the entire process of delivering energy. A customer providing some energy back onto our distribution grid is only providing generation, and should not be compensated for the other components of the electric delivery process. (See image below.) Our surrounding investor-owned utility has already adjusted their excess generation tariff rates. WPPI has been working with the PSC for several years to develop this adjustment for member communities. Earlier this year, this was approved for Sturgeon Bay Utilities. This fall, WPPI is planning to file a group filing for other member communities to adjust their tariffs accordingly. Over the past 12-months, the excess amount credited for excess generation has cost the utility over $57,000. This overpaying for purchased energy unfairly increases costs for all other electric customers. The proposed tariff acknowledges the capital investment made by some customers to install solar PV systems. Customers with existing parallel generation systems as of the effective date of the tariff adjustment will continue to be reimbursed at the retail rates for an additional 10 years. A formal request of support and approval to adjust the PSC tariff accordingly would be made at a future Utility Committee meeting. John Schuh, CPA Utility Accounting Manager 8 COMMITTEE REPORT – August 2026 Oconomowoc Electric Utility Did you know? On July 27, 2026, an EF-3 tornado decimated a large area of the Fox Valley, hitting the City of Menasha and Menasha Utilities extremely hard. The Municipal Electric Utilities of Wisconsin (MEUW) arranged for mutual aid, which is a network of other municipal electrical utilities offering their resources to help in times of need. Oconomowoc was called and sent 4 line workers on 7/29/26 to assist with the restoration of power in Menasha. On August 5th, we exchanged out 4 crew members, with 4 fresh people. In addition, our bucket truck and large hydrovac truck were sent along with some wire, connectors and 6 wooden poles to help replace over 120 broken poles and downed wires. According to the MEUW, a total of over 100 mutual aid line workers from 25 municipal utilities contributed to the restoration event. Crews were sent back home on Friday, August 7, 2026, after power was restored to all customers who were able to receive it. I would like to give proper recognition and thanks to the following employees who re-arranged their personal lives to give Menasha Utilities multiple 16-hour shifts. Oconomowoc employees include:  Group 1: Jason Otto, Dustin Gruling, Chad Garcia, and Matt Magnussen  Group 2: Todd Tremaine, Brandon Gorr, Tim Will, and David Arnott Picture of Damage from 7/27/2026 EF-3 Tornado in Menasha 9 Project Updates: As of August 11, 2026.  The following projects have been completed: o Arrowood #5 – install new streetlights o Costco – new service and metering for main store o Greenland Ave switchgear removal o Lisbon Rd. - B phase cable replacement due to age and condition o Lisbon Rd. - Streetlight replacement related to 1st phase of street project o 2nd St. – move anchor and guy wires in conflict with new bike path project o Shorewest Realty – new service to new office building o Lapham bridge project – install 2 streetlights in project area o Lisbon Rd/N Roosevelt Ave – bore across road for pedestrian crossing signals Services:  New Services/Meters: o 22 new residential services and 32 new electric meters were installed in July. o PSC required periodic testing of three phase electric meters is taking place for 2026. o 13 meters have been changed out for the PSC required testing/replacement of single- phase meters in July.  Customer calls/issues: o 7/29/26: 706 Roland St. – A phase transformer failure, 137 customers out, transformer has been replaced. o 8/3/26: 35855 Hewitts Point Rd – investigating possible neutral issue – recorder set o 8/5/26: 604 Glenview Rd. – secondary fault due to contractor dig-in Traffic Control Lights:  Nothing new to report Substations:  Nothing new to report.

Sampling targets high-risk sites. Action levels are 15 parts per billion (ppb) for lead and 1,300 ppb for copper. Exceeding 10% of samples triggers public notices and treatment changes. The purpose of the Lead and Copper Rule (LCR) sampling is to protect public health by minimizing lead and copper levels in drinking water. Lead and copper enter drinking water mainly through the corrosion of service line pipes and plumbing materials. The LCR establishes action levels for lead and copper based on a 90th percentile level of tap water samples. An action level exceedance (ALE) is not a violation but triggers additional requirements to minimize exposure to lead and copper in drinking water, including water quality parameter monitoring, corrosion control treatment, source water monitoring/treatment, public education and lead service line replacement. All community water systems are subject to the LCR requirements. Some of the key components include: 1. Stagnation time: Water must sit unused in pipes for at least 6 hours before sampled 2. Collection method: First draw from kitchen cold, unsoftened, after stagnation period 3. Site selection: Sites with confirmed lead service lines on both public/private sides 4. Frequency: Required to collect 30 samples every three years 5. Consumer notice: Utility to notify in writing the results within 30 days of lab results. Respectfully Submitted: Scott Osborn P.E. Water Superintendent 11 Wastewater Utility Committee Report August 2026 I. Accomplishments: a. The Evaluation and Preliminary Design Project was awarded to Donohue and Associates at the August 4 council meeting. This work will begin in earnest as soon as agreements are carried out. We anticipate this work will take 18 to 22 months. II. Upcoming Priorities: a. Work is ongoing on the chloride Source Reduction Measures (SRM) items for 2026. b. Installation of lift station communication devices will begin in the next week or two. We anticipate installations to continue at a rate of 3 to 4 per week depending on receipt of new units. c. Staff have narrowed down the maintenance software selections to two providers. We have the capability to beta test each for comparison over the next month. We want to ensure the selected software is efficient and functional for all staff members as the initial investment in time will be substantial. d. We will be bench testing Aluminum Sulfate compounds in the lab to compare with our current chemical, Ferric Chloride, for phosphorus removal. III. Challenges: a. One of the two pumps at Madison St. lift station has failed. Both pumps had been planned to be re-built in 2026. We are expediting repairs and have verified our backup trailer mounted pump can serve an alternative pumping method if needed. b. The second Grit System “tea cup” had been removed for repair. A previous repair to the other unit was very successful. This effort will renew the overall lifespan of this system at a very substantial cost savings versus replacement. IV. OWPP: a. The Oconomowoc Watershed Protection Program (OWPP) has received approval to install four new watershed signs within the public right-of-way at key locations along the boundary of the Oconomowoc River Watershed. The signs will alert motorists and visitors that they are entering the watershed and encourage everyone to help protect its water resources. b. The Oconomowoc Watershed Protection Program (OWPP), in partnership with Farmers for Lake Country, will host a fall field day on September 12th. The event is open to the public. Local government, municipalities, and other community partners are encouraged to attend and learn more about conservation farming practices which influence water quality of our lakes. V. Safety: a. This past month’s training included: i. Safety Refresher Handouts, Hard hats for field workers 12 b. Safety inspections/audits included observation of: i. Mowing activities – DPW & Parks, all employees found to be in compliance with appropriate PPE 13
