Improving Generator Reliability

One session of the 7EA User Conference dealt with generator reliability. The factors affecting reliability include the unique characteristics of each machine, its age/condition, history, operational and operator actions (cycling, loading, trips, restarts, synchronous condensing, motoring and so on), environment, external events and acts of god. The smart policy is to form a maintenance plan and carry it out systematically.

NRGreen Power

NRGreen Power and GE recently announced plans for a new recovered energy project that will produce power without additional emissions using the first global application of GE's ORegen system. The technology will be installed at Alliance Pipeline's Windfall Compressor Station near Whitecourt, Alberta, to generate electricity through the use of waste heat. The ORegen system is the latest in Organic Rankin Cycle technology.


Siemens is increasing its stake in Britain’s Marine Current Turbines Ltd. to 45 percent. Michael Axmann, CFO of the newly founded Solar & Hydro Division within Siemens’ Energy Sector said, “We will actively shape the commercialization process of innovative marine current power plants.” Effective October 1, 2011, Siemens realigned its renewables business into two independent units.

Andrew Tyler, CEO of MCT, said: “We are about to approach investors to secure funding for our first two tidal array projects.”

The Gas-Solar Alliance

This year's Solar Power International show in Dallas featured a panel promoting
the value of the solar and gas industries working together to their mutual
advantage. By 2015, analysts are predicting that another 140 GW of solar
capacity will come onto the grid. In the same time frame, natural gas should
bring on another 314 GW of capacity. If the estimate is correct, that will mean
gas accounts for 40 percent of the U.S. total while Solar reaches 20 percent.

User Group

The GE 7EA User Group met this month in San Antonio, Texas. The event kicked off with a reliability day and a presentation on oil analysis, and some key points were made. One of the points was that the primary reasons for oil analysis failure were that the vendor takes too long doing the analysis, and user delays in sending the samples. By the time the results are in, they are meaningless as too much time has elapsed.

New generation

Black Hills Corp. utility subsidiaries Black Hills Power and Cheyenne Light, Fuel & Power recently announced that they have filed for a certificate of public convenience and necessity with the Wyoming Public Service Commission to construct and operate a new $237 million natural-gas-fired electric generation facility within Cheyenne city limits. If approved by the Wyoming Public Service Commission, construction would begin in 2012, and the facility would begin serving customers in 2014.
