Work has begun on a $700-million ferronickel plant in eastern Cuba, near Moa, that is slated for completion in 2013. The Las Camariocas plant is the largest construction project now under way in the island nation. It has been undertaken by Quality Cuba S.A., a joint-venture contractor comprising Cuba’s state-owned engineering and construction firm, Quality Couriers International S.E.A., and the government of Venezuela. Upon completion, the plant is expected to annually produce 68,000 tons of ferronickel, which is an ingredient in stainless steel. Quality Cuba S.A. also is partnering with Brazil’s Odebrect to build a $600-million container terminal at the
The U.S. Army Corps of Engineers gave final approval July 27 to Central Maine Power, a subsidiary of the Spanish-owned company Iberdrola USA, to begin work on a $1.4-billion electricity transmission network, one of the largest construction projects in Maine’s history. The project includes five, 345-kV substations linked by 450 miles of new or rebuilt transmission line. The line’s southern end will tie into the New England grid near the New Hampshire border and its northern end will link with Canadian transmission lines in Orrington, Maine. The utility has contracted with Maine contractors Cianbro Corp., Pittsfield, and RJ Grondin &
More than any other European nation, the U.K. is pinning its hopes for a low-carbon-electricity future on offshore wind power. It already has more offshore generation than any other nation, at over 1,000 MW. But with construction costs posing the major hurdle to reach the U.K.’s goal of generating 12,000 MW by 2020, the quest is on for the best foundations in ever-deeper waters. Because of supply bottlenecks and other factors, the real construction cost of offshore wind farms has risen 20% since the first commercial schemes were built seven years ago, says Rob Hastings, head of marine resources at
Aiming to cut costs of offshore wind power, British engineers are developing a vertical-axis turbine that would eliminate the need for a tower, reduce stress on blades and foundations and ease installation work. The developer of the 10-MW device hopes to have a 1-MW proof-of-concept machine at work within two years. A full-scale demonstration would follow.

These arms rise from a vertical axle in a module sitting just above
Earthquakes, wind and ice can make electric service transmission poles topple like dominoes, costing millions of dollars to replace. Illustration By Walter Konefal div id="articleExtrasA" div id="articleExtrasB" div id="articleExtras" Jon Rouse, a civil engineering professor at Iowa State University, hopes to eliminate that cost by incorporating hinges into the base of poles to deflect stress and bounce the poles back—like Weebles, the 1970s toys that “wobble but don’t fall down.” Currently, the industry relies on sturdy and costly “dead-end structures” every five to 10 miles to block poles from cascading. Rouse’s 110-kv poles, now being tested at the university, eliminate
Conceding that they lack the votes--at least for now--to pass a comprehensive energy and climate-change bill, Senate Democrats instead will propose narrower legislation. Majority Leader Harry Reid (D-Nev.) said July 22 that he soon will introduce a scaled-back measure that includes more accountability for oil spills and a handful of other targeted provisions. After meeting with his fellow Senate Democrats, Reid told reporters that there are no Republican votes at present to support a wide-ranging energy measure. Reid said that "in the next few days" he will introduce a four-part energy package and that it would move to the Senate
A 290-MW photovoltaic powerplant is on track for construction to start later this summer in Arizona, marking the beginning of a wave of utility-scale solar projects expected to wash over the Southwest. Photo: Courtesy First Solar Designed to provide 290 MW of power, this Yuma-area project is expected to be the first of many solar powerplants. The push to build solar plants like the Agua Caliente project near Yuma is driven by two key factors: state renewable-energy requirements and a drop in solar prices, especially for photovoltaic technology. Nine western states have renewable portfolio standards requiring utility electric sales to
Groundbreaking took place this week for the $452-million Lodi Energy Cen-ter powerplant project in northern San Joaquin County. The California Energy Commission and Northern California Power Agency teamed up to get the project off the ground; the NCPA will construct, own and operate the plant. The center will be a natural-gas-fired, combined-cycle 255-MW power generation facility. Completion is scheduled for June 2012. A major component of the center will be a new technology: Designed to allow for the steam turbine’s earlier startup in a process that decouples the gas turbine from the heat-recovery steam generator, the technology is intended to
Alyeska Pipeline CEO Kevin Hostler will retire from management of the 800-mile Trans Alaska Pipeline System (TAPS) in September, three months earlier than planned. “Retiring at the end of September is good for the pipeline,” Hostler, 55, said in a statement. Photo: courtesy Alyeska Pipeline Service Co. Alyeska Pipeline CEO Kevin Hostler Hostler announced on July 7 that his last day is September 30. Members of the TAPS Owner Committee are now looking for a new CEO and will appoint an interim CEO if the position is not filled in time. Hostler’s announcement will not alter controversial staffing or maintenance
The planned construction of a $780-million wind power project in Kenya is about to get under way. The consortium heading the project announced it is close to selecting contractors for the construction of transmission lines, roads and bridges to and from the project site, located in the remote district of Marsabit. The completion of the 300-MW Lake Turkana Wind Power Limited (LTWP) project, Africa’s biggest, would increase the capacity of Africa’s installed wind turbines to more than 1,000 MW, or approximately 0.7% of the total worldwide capacity. The consortium, LTWP, led by Aldwych International (51%) and Industrial Development Corp. of
