  • Acquisitions Reset the Global Gas Turbine Market

    A series of acquisitions among major suppliers in the gas turbine market over the past couple of years has changed much of the global landscape for gas-fired power. Several long-standing firms have been swallowed up, while others have gained new prominence thanks to conditions laid on the big deals by regulators. What this means for […]

  • A 2016 Roundup of Power Sector Wheeling, Dealing, and Repositioning

    The past year saw an astonishing number of mergers, acquisitions, and business reconfigurations of electricity and energy companies, without any obvious organizing theory. Is it possible to make sense of the activity, or is it just business Brownian motion—aka, random behavior?  Gas companies spun off power generating assets. Power companies sold offshore businesses. Independent generators […]

  • Newtonian Shift Game Helps Power Industry Comprehend Transition

    How do you get generating company executives and those who interact with the power industry to think outside the box when planning for the future? The answer may involve a board game. Humans are pre-programmed to prefer routine, tradition, and regularity, without questioning whether longevity equals good. Fear of the unknown, and the power of […]
