A green power corridor

The Sunrise Powerlink transmission line project brings renewable energy from generation sites in the Valley to San Diego.

In the far southeastern corner of California on the border of Arizona and Mexico lies the arid Imperial Valley. Irrigation and the Colorado River have made it some of California`s most productive farmland, but this desert region is now also a hotbed of renewable energy projects.

It`s partly driven by California’s mandate to generate 33 percent of its power from renewable sources by the end of 2020, but also by the Valley’s excellent solar, geothermal and wind resources, its proximity to large population centers on the coast, and large tracts of otherwise unusable desert land.

The latest installation is the Sunrise Powerlink transmission line project, owned and operated by San Diego Gas and Electric, and built to carry renewable energy from generation sites in the Valley to San Diego (pop 1.3 million), 190 km away.

The line adds about1,000 megawatts (MW) of transmission capacity to Southern California`s power hungry electric grid, and will help maintain grid reliability in the most populous U.S. state. California`s aggressive renewable energy goals will require transmission lines capable of moving renewable energy from remote generation sites to urban centers where it is needed.

But even with the Sunrise Powerlink, solar and wind generation is more volatile than power generated by conventional means. This also affects power quality and calls for special technology to help capture and transmit renewable energy.

This technology includes the ABB Series Capacitor installed in the new 500 kV Suncrest substation, a key component of the Sunrise Powerlink. Series Capacitors improve power transmission capacity and preserve voltage stability of transmission lines, ensuring they can deliver maximum amounts of stable, usable power to users, particularly through bulk transmission corridors – another ABB specialty.

Since the Imperial Valley is a seismically active area, an ABB patented mechanical spring damper mechanism is incorporated in the SC platform design, and the equipment meets the IEEE`s (Institute of Electrical and Electronics Engineers) High Seismic Qualification level Standard 693.

Several utility-scale renewable energy projects are being built along the Sunrise Powerlink route, including  a solar photovoltaic project under construction by Tenaska Solar Ventures and the Pattern Ocotillo Express Wind project, which when completed will make the Sunrise Powerlink a truly green transmission corridor, a project ABB is proud to be part of.

    DEAR SIR
    NOW I AM HAPPY TO SEE THAT GREEN ENERGY IS FORMING
    AND HOPE NEW FUTURE WE COULD ACHIVE TO  HIGHER TECHNOLOGY
    TO GET ABILITY TO USE SUN ENERGY FOR ALLOVER THE WORLD
    I THINK  WE CAN  FIND BEST SOLUTION FOR SOLVE THIS MATTER.
    THEN WE CAN LEAVE OIL AND GAS AND HAVE BETTER CLIMATE AT THE SAME TIME WE USE OIL AND GAS AS A VALUABLE SOURSE FOR HUMMANITY.
     
    THAN YOU IN ADVANCE
    BEST WISHS

    Japan and Germany will pay residents between 32- 52 cents per kilowatt hour, here in California they will pay us 4 cents per kilowatt hour, want to change our Feed in Tariff? Campaign to allow Californian residents to sell electricity obtained by renewable energy for a fair pro-business market price. Will you read, sign, and share this petition?http://signon.org/sign/let-california-home-owners

    India is having lots of power generation and renewable energy. GTP IS ALSO MORE GENERATION IS NOT SUFFICIENT AND FAILURE OF GRIDS, LOSSES, NATURAL CALAMITIES POWER CUTS ARE MORE. HOW THESE SYSTEMS IMPLEMENTED IN OUR COUNTRY WHERE WE NEED THIS MORE.
