Utility Capital Markets Counsel in 2026: Big Tickets, Repeat Clients

A treasurer choosing utility capital markets lawyers is buying for large deals that recur. Sartori & Partners data show 949 utility, water and waste deals in the 12 months to October 2026, and those deals came from 377 distinct clients. Where a value was disclosed, the median deal was $802.5 million, the highest in this comparison, which sets utilities against power and renewables, banks and financial institutions, and the capital markets practice as a whole. Capital markets lawyers worked on 62.3% of the sector's deals. The outside counsel decision for a utility is less about finding a firm for one transaction and more about choosing a bench that can carry large mandates again and again.

The median disclosed utility deal was $802.5 million, against $660 million for banks and financial institutions and $500 million for power and renewables. The utility median is 1.6 times the power median, although the two sectors sit side by side in energy and share several advisers. Across every capital markets deal on record, whatever the client sector, the median was $563.2 million. A median rests only on deals with a disclosed value: 32.5% of utility deals carried one, against 27.7% in power and 24.1% for banks, so each comparison stands on a minority of the sector's work. The direction is still clear. For a utility the consequence is staffing: at a median of this size, the firm on the mandate has to field partners who run deals of that scale routinely, and the engagement letter should name them.

In the Sartori & Partners deal record, 377 utility clients accounted for 949 deals over 12 months, or 2.5 deals per client. Power and renewables ran at 2.1 deals per client, banks and financial institutions at 2.6, and the capital markets practice across all sectors at 2.6. On frequency, utilities sit close to banks and to the practice average, and above power, whose deal count is spread across many more clients. The repeat pattern matters more than any single price. A utility that returns to market several times a year gains from standing terms: one team that stays on the account, documents that carry over from one offering to the next, and rates agreed once. Treating each deal as a fresh pitch gives that advantage away.

Across all dated deals, capital markets lawyers appear on 26.4%; on utility deals the figure is 62.3%, and on bank deals 51.0%. Power and renewables, the closest neighbor, runs the other way: capital markets lawyers worked on 26.0% of its deals, while projects and infrastructure lawyers worked on 32.9%. Inside the utility mix, corporate and M&A lawyers came second at 16.2%, then banking and finance at 7.3%; one deal can involve several practices, so these shares overlap. Seen from the practice side, utilities are the client sector on 4.7% of all capital markets deals, ahead of power and renewables at 4.1%. For a general counsel, the capital markets partner is the relationship that shapes the panel, and the M&A and finance benches form the second layer.

Utility deals rose 13.6% year on year, from 861 to 978 in the settled 12-month windows. The capital markets practice as a whole rose 10.0%, from 11,838 to 13,024, and all dated deals rose 10.6%. Power and renewables grew faster still, rising 27.6%, while bank and financial institution deals rose 7.2%. The partners who know regulated energy assets are therefore busier than a year ago, with utility and power clients both adding work. A utility planning an offering should confirm the named team's availability before the market window opens, not after the mandate is awarded.

New York remains the main base: 46.3% of the sector's deals were handled with lawyers in New York, against 32.9% of power and renewables deals. The sharper gap is in Texas. Lawyers in Houston worked on 22.1% of utility deals and lawyers in Dallas on 17.6%; for power and renewables the figures were 12.2% and 5.3%. London and Washington run the other way, at 11.9% and 10.1% of utility deals against 19.0% and 17.0% in power. One deal can count in several cities, so these shares overlap and are never added together. A utility with a recurring bond or equity program should expect part of the work to run through Texas offices, and should ask whether the firm's Houston or Dallas team holds the relationship or only supports New York.

The utility list below counts all of the sector's deal work, not only capital markets mandates; there is no separate ranking for capital markets work on utility deals. Set against the capital markets practice's own ranking across every sector, six names appear on both: Latham & Watkins, Davis Polk & Wardwell, A&O Shearman, Sidley Austin, Simpson Thacher & Bartlett and Linklaters. The other four on the utility list, Hunton Andrews Kurth, Morgan, Lewis & Bockius, Troutman Pepper Locke and Gibson, Dunn & Crutcher, rank among the sector's ten without a place in the capital markets ten, a sign of sector depth that a ranking by issuance volume does not capture. Sartori & Partners counts individual deals for these lists, shown as bands rather than exact totals. A panel that pairs one firm from the overlap with one sector specialist covers both the volume of offerings and the regulatory knowledge a utility needs.

First, judge fees against the size of the work. With a disclosed median of $802.5 million, utility deals sit above bank and power deals, and a proposal should be read against deals of that scale, not against the practice-wide median of $563.2 million. Second, buy for frequency. At 2.5 deals per client in 12 months, a utility is a repeat client, and the terms of a standing program are worth settling once rather than deal by deal. Third, test the Texas bench: with 22.1% of the sector's deals handled with lawyers in Houston, a firm without real depth there will staff part of the work from elsewhere. Fourth, expect competition for the same partners, since utility deals rose 13.6% year on year and power deals rose 27.6%. Sartori & Partners builds these figures from public law-firm announcements, firm websites and professional profiles, checked monthly.
