  • China Begins Operation of First CPR-1000

    The first unit of Ling Ao phase II (Unit 3) in Guangdong Province, China, entered commercial operation in late September. The 1,080-MW reactor is the first CPR-1000—a Chinese design—to be built, and its start-up marks a major milestone in the country’s concerted nuclear power expansion.

  • Microturbine Technology Matures

    Microturbine technology has evolved from early systems of 30 kW to 70 kW to today’s systems, which can have individual ratings of 200 kW to 250 kW. Packages up to 1 MW are now available that can be assembled into multipac units for projects of 5 MW to 10 MW. These modern units are packaged with integrated digital protection, synchronization, and controls; they produce high combined heat and power efficiencies; and they are capable of using multiple fuels.

  • Correction (November 2010)

  • NERC: EPA Regulations Could Impact System Reliability

    Regulations being proposed by the U.S. Environmental Protection Agency (EPA) could significantly affect the bulk power system’s reliability, a new report from the North American Electric Reliability Corp. (NERC) shows. The quasi-public agency recommends that the proposed rules provide sufficient time to procure replacement resources that would offset capacity reductions expected as a result of unit retirements and deratings from environmental control retrofits.

  • E.ON Pulls Plug on Kingsnorth CCS Project in the UK

    E.ON last week shelved plans to build its controversial Kingsnorth coal-fired plant in Kent, and it withdrew from the UK’s government competition to build the first of four planned large-scale pilot power plants to demonstrate carbon capture and storage (CCS). The company said the project could not meet “competition timescales.”
