DTE Energy

1995

A coal-dependent utility masquerading as a diversified energy company — its non-utility projects are real, but their economics are invisible.

DTE Energy is a Michigan-centric utility with a fossil-heavy generation profile and an opaque non-utility expansion. Its business model relies on regulatory protection, not market innovation.

  1. 1:01
    The Regulated Core

    DTE is first and foremost a Michigan utility — not a national energy platform.

  2. 2:50
    The Generation Gap

    In 2022, over half its electricity came from coal — not a transition, but a continuation.

  3. 5:01
    The Unmeasured Expansion

    Its non-utility arm spans 15 states and three sectors — but with no financials attached.

  4. 6:51
    The Geography Claim

    Calling itself 'national and international' stretches the meaning of both words.

Worth your time?

Yes. Study the whole thing.

The written brief1 min read

What the company or idea is

DTE Energy is a Michigan-based, vertically integrated energy company: a regulated electric and gas utility serving 2.3 million and 1.3 million Michigan customers respectively, plus a portfolio of non-utility energy projects across 15 U.S. states.

How it actually makes money

DTE Energy makes money through regulated electric and gas utility operations in Michigan, where it charges customers under state-approved rates, and through non-utility businesses — including industrial energy services, renewable energy projects, and energy marketing — operating across 15 U.S. states.

What works

Its regulated utility model delivers stable, predictable cash flow from 3.6 million Michigan customers. Its non-utility arm has geographic reach — 74 projects across 15 states — and operational focus across industrial, renewable, and environmental services.

What does not

Its 2022 generation mix remains coal-dominant at 54.16%, undermining climate claims. Its non-utility arm operates 74 projects but no revenue, margin, or capital allocation data is provided — making scale and profitability unverifiable.

What to take from it

DTE exemplifies the modern utility paradox: a state-protected monopoly using regulatory certainty to fund diversification — while delaying systemic shifts away from coal, with no disclosed financial weight given to its non-utility ventures.

Is it worth your time

Yes — if you are assessing how legacy utilities manage the tension between regulatory capture, fossil-fuel dependence, and expansion into unregulated markets. No — if you expect evidence of structural decarbonisation or scalable non-utility margins.

MeituanWang Xing · 2010Meituan is a Chinese technology company headquartered in Beijing that operates a platform for local services, including on‑demand food delivery, in‑store services, consumer reviews under Dazhong Dianping, hotel and travel bookings, and instant retail. It monetises through fees on its platform, taking a commission on food delivery orders and charging merchants for booking and in‑store services. Meituan’s rapid user growth is driven by its extensive coverage of local services, its integration of food delivery, in‑store services, and hotel bookings creating a one‑stop shop, and its large merchant base of 14.5 million active merchants providing network effects. Meituan faces regulatory scrutiny in China, its 2021 post by Wang Xing triggered a 7.1 % share plunge and anti‑monopoly investigation, and the company has been subject to scrutiny by Beijing Municipal Human Resources and Social Security Bureau. Meituan demonstrates the power of a diversified local‑services platform, its ability to scale across cities and internationally shows the importance of network effects, and its regulatory challenges highlight the need for compliance awareness. Meituan offers a case study in rapid scaling and diversification, but its regulatory risks caution investors.
