Hydro Review ENsights: 45 years ago, U.S. West drought conditions were worse

Also, NYC hydropower transmission line contracts signed

DeZURIK’s Hilton Throttling Knife Gate Valve is an economical, non-cavitating, low level outlet valve for dams with operating heads of less than 200 feet. It provides the variable, regulated flows required by the most dams in the U.S. The throttling knife gate valve may be installed as a free discharge valve or upstream of the outlet discharge. Unlike standard knife gate valves, this design uses a square gate that is fully supported over the complete travel length to prevent vibration and noise.

Are you looking for a segmented axial or radial shaft seal with a proven track record? Opt for Thordon SXL segmented axial and radial seals for a solution that is proven to last longer and reduce life-cycle costs compared to carbon graphite seals. SXL is exponentially more abrasive resistant and routinely replaces carbon graphite and phenolic seal segments. Watch our video and learn how easy SXL is to handle and install.

A new report by hydrologists at Pacific Northwest National Laboratory (PNNL) suggests that the relationship between drought and hydroelectric power is more nuanced than it might seem. Recent headlines have focused on drought conditions across the Western U.S., but often miss the fact that the region’s hydro conditions remain largely viable and in some cases are improving. To paint a…
A transmission line to deliver hydroelectric power took a step forward as Champlain Hudson Power Express finalized contracts with three companies to oversee major construction work on the 339-mile-long underground transmission line that will deliver 1,250 MW of energy from Québec to New York City. Transmission Developers Inc., a Blackstone portfolio company, selected NKT, Kiewit Power Constructors Co., and Hitachi…
The German Federal Government has acquired a 99% stake in Uniper, signaling the company’s nationalization. The nearly 100% stake was acquired as Uniper and the German government, alongside previous majority shareholder Fortum, agreed on an amendment to the stabilization package announced on July 22, 2022 to ensure the ailing company’s stability. Uniper’s primary generating technology is gas, with 17 GW…
Brazil’s electric power watchdog Aneel approved, in most cases, the results of 2022’s A-4 auction for new energy, including 18 small hydro projects. The tender was held May 27 for contracting electric power from new generation projects to supply the demand of Cemig, Coelba and Light as of 2026. According to BNamericas, the 19 projects approved have total installed capacity…

Scientists with the National Renewable Energy Laboratory have received a patent for a fledgling technology domain – distributed embedded energy converter technologies, or DEEC-Tec – that will be applied for marine energy converters. The invention’s first patent is for applications in marine renewable energy from ocean and river waves, currents and tides. But DEEC-Tec (pronounced deck-tech) could eventually transform sources…
A specific focus on sustainability appears to be the key to securing support and eventually achieving long-term infrastructure objectives.
UPCOMING EVENTS
GridTECH Connect Forum will provide an intimate, solutions-driven environment for energy leaders to network, learn, and collaborate outside of their traditional silos for the first time. The events will focus on the interconnection of distributed energy resources — solar, storage, electric vehicles, microgrids, demand response programs, and more.
Watch on-demand at a time that fits your schedule.
Join us July 11-13, in Charlotte, North Carolina for the largest hydropower and dams industry event worldwide hosting over 2,500 hydroelectric power professionals discovering new solutions and networking with industry peers.
The Department of Energy’s Oak Ridge National Laboratory is providing hydropower operators withnew datato better prepare for extreme weather events and shifts in seasonal energy demands caused by climate change. For the new report, ORNL researchers used downscaled global climate projections to simulate future hydrologic conditions at 132 federal hydropower facilities across the U.S. The projections are expected to enable…
Long-term goals to have hydropower meet 46% of Pakistan’s power generation needs by 2030 “could be risky” due to various challenges, according to a report from the Institute for Energy Economics and Financial Analysis (IEEFA). Hydropower has been favored in Pakistan’s renewable energy planning, and it provides almost 30% of the power generated. But the report by Haneea Isaad, energy…
