Highlights from the World of Linemen News
The Black Sea transmission network project is the largest electric power project implemented in the Republic of Georgia since the early 1990s, when Georgia regained independence. The project actually dates back to the 1980s, when construction of a 258-km (160-mile) 500-kV overhead transmission line commenced to interconnect two existing substations, Zestaponi and Gardabani, with the line routed through southern Georgia to create a 500-kV loop.
With a transmission system designed for an independent state, Georgia had to overcome the challenge of breaking down existing border barriers and connecting transmission systems with different technical parameters to establish a means of exporting surplus renewable energy. Read More
Tesla hopes to gain traction for its new Solar Roof by installing the system on its employees’ homes, according to TechCrunch. The roof will cost an average of $21.85 per square foot, which the company says is less than the cost of a conventional roof over its expected 30-year lifetime.
According to the latest white paper from the American Council for an Energy Efficient Economy, titled “Unlocking Ultra-Low Energy Performance in Existing Buildings,” the United States is seeing a promising upward trend in ultra-low energy buildings (ULEBs). While much of this growth is occurring in new construction, the paper notes that growth is also occurring with existing buildings.
“It is estimated that more than half of the homes and buildings that will be in use in 2050 are already built and in use today,” the report states. “Yet efforts to scale up retrofit activity in both the residential and commercial sectors lag far behind the market potential, even for standard retrofits that do not target deeper energy savings.” Read More
California linemen competed alongside line workers from across the country for the opportunity to earn a spot on the 2017 International Lineman’s Rodeo team at the West Coast Rodeo on July 29. Pacific Gas & Electric (PG&E) and IBEW 1245 sponsored the sixth annual event at PG&E’s training center in Livermore, California… Read More
Today, some buildings can produce more energy than they use. Spurred by successful net-zero energy projects (also called zero-net), net-positive endeavors demonstrate the possibilities and potential in building design.
The small step from net-zero to net-positive could present a new world for buildings, public utilities and city planners… Read More
