The extension consists of an additional 800 kV power line between two existing 800 kV substations that were built some 25 years ago. ABB will expand and upgrade the two substations on a turnkey basis, integrating existing third-party components with state-of-the-art ABB 800 kV equipment. The customer is Edelca, Venezuela’s largest electric utility. Within the turnkey contract ABB is also responsible for engineering, erection, managing and commissioning both substation projects, as well as ensuring that completion takes place exactly on time, ready for transmission in July 2008. Supplying the world’s 800 kV grids Although ABB has previously supplied 800 kV power transformers and high voltage equipment to countries with 800 kV systems - including Brazil, Canada, Russia, South Africa, South Korea and the United States - this is the first time that ABB has been awarded a turnkey substation contract for the extra high voltage rating. ABB has a longstanding position as the market and technology leader in extra-high and ultra-high voltage power transmission, both in the delivery of AC and DC bulk transmission systems to power grids all over the world and as the innovator of groundbreaking technologies that make reliable and low-loss transmission at 800 kV possible. These technologies include HVDC （high-voltage direct current）, for which ABB last year opened the world’s first testing facility for 800 kV; and FACTS （flexible AC transmission systems）, which enabled ABB to be first to develop transmission systems for 400 kV, 500 kV and progressively up to 800 kV. Helping Edelca deliver clean hydropower The Guri dam is the world’s second largest hydropower plant, and generates the power for Venezuela’s 800 kV transmission system. ABB is currently upgrading the control, protection and instrumentation systems of the 20 generating units, and is modernizing part of the 230/400/800 kV switchgear in the plant’s three high-voltage switchyards. ABB has also supplied several 400 kV and 230 kV substations to Edelca. One of the most important of these is the substation for the 2,160 MW Caruachi hydropower plant, which was connected to the grid in 2004. The power transmission interconnection between Venezuela and Brazil, with two substations at 400 kV and one at 230 kV, was built and delivered by ABB in 2001.[/color][/font]
