Scott Lauber and the arithmetic of keeping the lights on

In 2014, Scott Lauber had to explain what happens when one utility company buys another. His audience was the Illinois Commerce Commission. His subject included accounting entries, financial planning and the proposed acquisition of Integrys Energy Group. It was the sort of assignment unlikely to inspire a movie. Yet it offers a useful opening scene for the career that followed. Before Lauber was responsible for deciding where a major energy company would go, he was responsible for explaining how its numbers worked.

Twelve years later, the company that transaction helped create has a $37.5 billion investment plan for 2026 through 2030. Lauber is its chairman, chief executive officer and president. Wisconsin is attracting electricity-hungry data centers, and the arithmetic now reaches well beyond a hearing room. It reaches the household opening its utility bill, the factory planning an expansion and the new computing campus expecting power when construction is finished.

His route to this point began with a much smaller number: 1990, the year he joined Wisconsin Energy. The useful thing about that date is the distance it puts between arrival and authority. Lauber spent decades inside the business before becoming its chief executive. The grid acquired a new set of demands while he was learning the old set of obligations.

The accountant at the witness table

Lauber studied accounting at the University of Wisconsin-Whitewater, graduated with honors and became a certified public accountant. Before joining the utility, he worked in Arthur Andersen’s Milwaukee office. His early professional vocabulary was built around accounts and audits. In a business that must finance expensive equipment long before customers use it, that vocabulary has practical consequences.

The 2014 testimony makes those consequences unusually clear. As Wisconsin Energy’s vice president and treasurer, he described work that covered long-range financial planning, revenue requirements, treasury and cash management. He had also helped prepare financial elements of rate cases, including budgets and sales forecasts. A utility’s budget, in other words, was already connected to the prices its customers might be asked to pay.

He was explaining the proposed Integrys acquisition, including its accounting implications for Peoples Gas and North Shore Gas. The subject matter required precision about what would change on corporate books and what remained under review. There is a particular kind of responsibility in such work: a number has to survive questions from people whose job is to examine it, rather than applaud it.

WEC Energy Group was formed in June 2015. Lauber became its vice president and treasurer. The next April, he became chief financial officer. By then, the company’s new name sat on top of an organization he had known through years of financial work. His advancement came with continuity, but also with a larger set of decisions to answer for.

When the spreadsheet meets the plant

In June 2020, Lauber moved into the chief operating officer role. The remit included power generation, major projects, information technology, supply chain, supplier diversity, and infrastructure and fuels. Those responsibilities put the financial plan alongside the machinery and organization needed to carry it out. A funded project still needs equipment, people and a workable sequence.

That move matters to the shape of his career. A finance executive can spend years evaluating the consequences of investment. An operating executive must deal with the conditions that determine whether investment becomes useful service. Lauber had responsibilities on both sides before he became president and CEO in February 2022, succeeding Kevin Fletcher.

Gale Klappa remained an important figure in the company’s leadership. A photograph from WEC’s 2022 climate report puts Klappa and Lauber together beside a marble staircase. The setting is formal; the assignment behind it was less comfortable. They were discussing how to change an energy system while continuing to deliver affordable and reliable service. The photograph catches a succession still in progress.

On May 7, 2026, the board appointed Lauber chairman after Klappa retired from the board. The company also gave Klappa the honorary title of Chairman Emeritus. For Lauber, the chairmanship added governance responsibility to the operating leadership he had already held for four years. The long internal career had reached the board’s central seat.

Wisconsin’s new appetite

The next assignment is being shaped by customers with an unusually large appetite for electricity. Data centers are physical buildings with a digital purpose. Their power requirements have to be met through generation, wires and connections. The cloud, for all its airy branding, is a demanding tenant.

In a February 2025 interview, Lauber put the immediate problem plainly: “Economic development is strong in Wisconsin.” He discussed the additional capacity, distribution and transmission needed to meet that development. His answer connected a regional business story to the work of a utility. An announcement of new investment elsewhere becomes a construction and financing assignment for the energy provider.

“Economic development is strong in Wisconsin.”

Scott Lauber · February 2025

By August 2026, WEC was describing a five-year capital plan of $37.5 billion. Its scope includes electric generation, electric distribution, natural gas distribution, liquefied natural gas capacity in Wisconsin and transmission. This is a collection of different systems and projects, each with its own purpose. The total attracts attention; the details determine what customers actually receive.

Lauber’s career makes the questions behind that total especially interesting. Treasury experience concerns how a company obtains and manages money. Operating experience concerns the assets that money buys. At this scale, the two are inseparable. A delay, a changed forecast or a financing decision can alter the economics of a project long before its first useful unit of electricity arrives.

The customers already here

Growth creates another question, and it is the one a household is entitled to ask: who pays? New infrastructure may be needed because of a new, very large customer. Existing customers still expect dependable service and a reasonable allocation of costs. The arrival of a large project does not make that expectation disappear.

In May 2026, Wisconsin regulators rejected a proposed arrangement under which customers would have shared some costs associated with powering data centers. They instead called for the technology companies or developers to bear costs tied to the plants and transmission built to serve them. Lauber’s work therefore unfolds within a public process that can change the financial terms of growth.

The generation choices are contested too. WEC has delayed retirement of Oak Creek coal units, while environmental groups have criticized the implications of continued fossil fuel use. The company’s near-term carbon reduction goals were paused amid tight energy supply. These are material complications in the transition Lauber helps direct, and they give the phrase “reliable energy” a difficult set of practical questions.

The company’s August 2026 responsibility update described a mix of modern natural gas generation, renewables and battery storage. It reported a 53 percent reduction in carbon dioxide emissions from electric generation compared with 2005 and retained its long-term goal of net carbon neutral electric generation by 2050. The reported reduction and the future goal belong in different columns. One measures progress to date; the other remains an obligation ahead.

A second set of commitments

Lauber’s public work also extends into Milwaukee’s civic institutions. He serves on the boards of American Transmission Co., the Metropolitan Milwaukee Association of Commerce, and United Way of Greater Milwaukee & Waukesha County. Together, those positions place him in conversations about infrastructure, regional business and community needs.

For United Way’s 2025 community campaign, he joined Kurt Bechthold of Walbec Group, Steve Booth of Baird and Raquel Filmanowicz of VC 414 as a co-chair. The campaign launched with a $56 million goal. Its priorities included family homelessness, employment barriers and access to technology. These are local questions with specific organizations, donors and volunteers attached to them.

That December, the We Energies Foundation and employees pledged almost $1.5 million to the organization. Employees committed more than $300,000, and the foundation contributed more than $1.1 million. Those were collective commitments, and their scale should remain attached to the people and institution making them. Lauber’s role was campaign leadership within a broader civic effort.

It is a useful addition to a career often described through titles. The company operates in communities that also supply its employees, customers and civic partners. His United Way role makes that relationship visible beyond a balance sheet. A campaign goal, like an infrastructure plan, is a promise that requires many people to turn it into something usable.

The arithmetic continues

In July 2026, WEC reported second-quarter net income of $299.2 million, compared with $245.4 million a year earlier. Lauber emphasized customer service, financial discipline and operating efficiency. The vocabulary was familiar to the accountant who had spent years with budgets and forecasts, even if the scale of the assignment had changed.

His career gives the present moment an unusual depth of context. He has been inside the company before and after its 2015 formation, through finance and operations, and now through a change in board leadership. The experience does not settle the arguments over future investment. It explains why the decisions have landed on his desk.

The next chapter will have visible measures: equipment placed in service, customers connected, bills paid and emissions recorded. For someone who began by explaining the numbers, that is a demanding final examination. Every forecast must eventually meet an ordinary evening, when someone reaches for a light switch and expects the arithmetic to have been done.
