Public utilities constantly interact with state and federal regulators. John helps public utilities develop strategies to obtain regulatory approvals and leads litigation before regulatory commissions. He assists utilities with legislative proposals that may impact operations or the regulatory structures that govern them. John counsels on innovative alternative regulation proposals, competitive marketplace disputes, rate increase requests and rate design, acquisitions and merger approvals, service standards, and regulatory rules.

John began his career as a regulator, first as an Administrative Law Judge and later as Chief Administrative Law Judge at the Illinois Commerce Commission, the agency that regulates public utilities, including electric and gas utilities. He now counsels natural gas, electric, and water and sewer utilities, as well as large suppliers of electricity, gas and petroleum. John helps clients avoid regulatory pitfalls, developing successful solutions when problems do arise and providing support as industries and the regulatory environment in which they operate evolve.

Prior to Benesch, John played a key role in obtaining regulatory approval for a pilot program that incentivized renewable natural gas production facilities to locate within Nicor Gas Company’s service territory and provide this environmentally friendly fuel source to customers. He led a team that developed a strategy to present the idea as an alternative regulation plan and crafted the evidentiary presentation to support the proposal, marking it as the first of its kind in Illinois.

Representative Experience

  • Represented ComEd in litigating a request for regulatory approval of its first-ever Multi-Year Integrated Grid Plan, and a corresponding Multi-Year Rate Plan. Together, the plans detail every dollar the company plans to invest in providing electric delivery service over the next 4 years. In addition to ComEd, the case involved 12 parties. A total of 61 expert witnesses offered testimony, including 17  witnesses on behalf of ComEd. The regulator - the Illinois Commerce Commission - approved a $595 million increase in ComEd's revenue requirement and a $3.57 billion increase in rate base over the 4-year period. These figures represent approximately 88% of the values ComEd sought as of the close of the evidence, despite an extremely challenging regulatory environment. The market reacted very positively to the news, causing a marked increase in the value of ComEd's parent company, Exelon.
