ABB wins $20 million HVDC refurbishment order

ABB has won an order worth about $20 million from Vermont Electrical Power Company VELCO to refurbish a more than 25-year old HVDC high-voltage direct current transmission station.

The original station was delivered by ABB in 1985. The order was booked in the first quarter.

ABB will modernize the Highgate back-to-back converter station, which links the electrical systems of the state of Vermont and the province of Quebec. A contract to import hydropower to Vermont from Quebec has recently been extended for another 25 years.

The project’s scope includes the installation of ABB’s state-of-the-art control and protection system MACH2, and replacement of the valves and valve cooling system. The planned outage time for the link is only 21 days – an important factor that will minimize the impact of the station being out of service. The upgraded station is expected to be in operation by the end of 2012.

“The upgrade of the HVDC station will bring greater transmission efficiency, improve stability and provide greater security of power supply,” said Martin Gross, head of ABB’s Grid Systems business, a part of the Power Systems division. “It will also facilitate the transfer of clean hydropower from Canada.”

The MACH2 system is the world's most popular control system for HVDC and FACTS with over 700 systems in operation. It is extensively used across a range of installations from highly demanding HVDC Light installations, to large HVDC power links with power ratings of over 6,400 megawatts MW.

From smart meters to big batteries, co-ops emerge as clean grid laboratories

WASHINGTON - Minnesota electric cooperatives have quietly emerged as laboratories for clean grid innovation, outpacing investor-owned utilities on smart meter installations, time-based pricing pilots, and experimental storage solutions.

“Co-ops have innovation in their DNA,” said David Ranallo, a spokesperson for Great River Energy, a generation and distribution cooperative that supplies power to 28 member utilities — making it one of the state’s largest co-op players.

Minnesota farmers helped pioneer the electric co-op model more than a century ago, pooling resources to build power lines, transformers and other equipment to deliver power to rural parts of the state. Today, 44 member-owned electric co-ops…
