The energy industry is being impacted by rapid and disruptive changes faced in today’s environment. We are witnessing a wholesale shift away from fossil fuel generation to renewables, very low natural gas prices, changing environmental regulations, the growth of microgrids and distributed generation, and heightened interest in regional transmission and reliability. Combined, these changes are influencing state and federal energy policy and prompting regulatory action. This activity can create opportunities for entities that proactively plan.

At Calfee, we provide our clients with strategic support based on decades of experience, a track record of success at the state and federal levels, public policy advocacy and deep transactional experience. Our lawyers include a former utility regulator and general counsel, former Director of the Ohio EPA, and several other attorneys with decades of experience – both in house and as outside counsel – handling the full range of issues confronting energy companies, utilities and large consumers of energy.

Our clients have included a broad range of investor-owned utilities, municipal utilities, regional transmission organizations, telecommunications entities, pipeline companies, coal companies, investors, lenders, renewable resource developers and utility customers.

State Regulatory Matters. Our attorneys have successfully represented clients before state utility commissions throughout the Midwest, including the Public Utilities Commission of Ohio, Indiana Utility Regulatory Commission, Illinois Commerce Commission, Wisconsin Public Service Commission, Missouri Public Service Commission, and the Iowa Utilities Board. Our clients benefit from our experience counseling clients through complex regulatory issues, including rate cases, certifications for public convenience and necessity, rule makings, and M&A and utility asset transfers.

Federal Regulatory Matters. Our attorneys have extensive experience representing clients before the Federal Energy Regulatory Commission in rule makings, tariff and rate schedule filings, complaint proceedings and enforcement actions. Our attorneys regularly assist clients in the development and implementation of strategies around wholesale electricity market design, new market entry, large-scale integrations, and complex, multi-jurisdictional matters involving both federal and state regulation. This experience also includes representation of clients in appeals of agency actions before the U.S. Court of Appeals for the D.C. Circuit.

Renewables and Energy Transactions. We enable our business partners to capitalize on a variety of energy industry opportunities, including power purchase agreements, brokerage agreements, creation of microgrids, electric power and natural gas supply purchases, interconnection agreements, asset transfers, market entrance and integration analysis, and environmental permitting. These efforts have included the negotiation of contracts for the installation of onsite solar power production, including related lease agreements, power purchase agreements for the off-take of the power produced by onsite solar systems, as well as onsite microgrid projects.

In addition, we advise our clients on the implementation of on-bill and off-bill customer-facing service and product offerings. We also assist with navigating permitting, insurance, and other compliance considerations, and negotiating financing and underwriting arrangements, supplier agreements, and software and licensing contracts—all while helping clients control and mitigate their risk while diversifying offerings to ratepayers and customers.

Energy and Environment. Calfee provides energy clients with a full range of environmental counseling from the initial permitting stage through operational issues. Clients have included underground coal production, pipeline permitting and construction, natural gas and coal-fired electric generating units, and alternative fuel providers. These services include Clean Water Act NPDES and Section 401 and 404 permitting, Clean Air Act permitting, Power Siting Board permitting, compliance counseling, and defense of enforcement actions against these providers once the infrastructure has been completed.

Public Utility, Energy and Telecommunications Litigation. Because of Calfee’s extensive knowledge of the utility business, our litigators bring a unique problem-solving perspective to litigation involving utilities and energy companies. We routinely represent our clients in litigated matters before state and federal regulatory agencies. Moreover, our lawyers are experienced state and federal trial and appellate litigators, handling a wide range of disputes that include personal injury and other tort claims, tax, real estate, environmental and securities claims related to the energy industry.
