RWE’s Thomas Birr on Corporate Strategy in a Changing German Electricity Ecosystem

RWE AG is Europe’s third-largest electricity and fifth-largest gas marketer, with holdings in upstream oil and gas production, power grids, and energy trading.

The EEI’s Campaign for Electric Utility Industry Supremacy

At the Edison Electric Institute (EEI) annual meeting this week in Las Vegas, the tone was one of collaboration with partners from Washington to distributed generation companies. Those partnerships will be needed as the investor-owned utility (IOU) industry fights not so much a war on coal as a war for mindshare and wallet share in […]

Blurring the Line Between Temporary and Permanent Power

Temporary power may be the most widely distributed “distributed” generation worldwide, and its distribution is spreading, thanks to its ability to quickly meet urgent needs not only for event, construction, and post-disaster emergency power but also for fast-growing economies and stressed grids. That’s making it a serious competitor for “permanent” power in some situations. When […]

In addition to a presentation about a microgrid being developed for Necker Island—owned by Sir Richard Branson, founder of the […]

The State of the Microgrid Market: Promise and Present Realities

If, as Navigant Research suggests, the global microgrid market will exceed $40 billion annually by 2020, where is all the capacity going, and what’s fueling it (literally and figuratively)? Peter Asmus, a long-time researcher of smart grid technologies at Navigant, shared that market projection and others at the 4th Military & Commercial Microgrids Summit in […]
