California’s grid gurus say they can make it through this summer, but the future may pose real problems for a hydro-heavy regional system. As the grip of California’s four-year drought tightens, will the long-running event crimp electricity generation in the state? So far, according to the California Independent System Operator (CAISO), which dispatches much of […]

In the opening move of what is certain to be a long and contentious process, Sen. Lisa Murkowski (R-Alaska), chairman of the Senate Energy and Natural Resources (ENR) Committee, introduced a suite of bills covering a broad range of energy issues, from infrastructure to regulatory reform to civil enforcement. Along with several others introduced by […]

ALLETE Inc., a Minnesota holding company known mostly for its Minnesota Power subsidiary, is making a major strategic transition into the broader world of energy services, exemplified by its recent purchase of U.S. Water Services. At the same time, Minnesota Power, which previously transitioned from hydro to coal, now is shifting to a portfolio of […]

The ongoing record drought in California has caused significant changes in the state’s power mix as water available for hydroelectric generation becomes increasingly scarce, according to a recent report from Oakland-based nonprofit the Pacific Institute. The California Independent System Operator warned last year that water shortages were likely to substantially impact the state’s generation, with […]

Water is the lifeblood of a thermal power plant. As such, obtaining clean and pure makeup water and dealing with wastewater has been a requirement since the first steam generating unit went into operation. As

Worldwide, the U.S. is the largest producer of geothermal power; however, geothermal energy provides less than 0.5% of total generation in the U.S. Given geothermal’s small piece of the U.S. electricity pie

Alloys found in the condensate and feedwater systems of power plants include carbon steel for piping, pumps, and in some cases heat exchangers. Many systems still have some copper-based alloys from admiralty

Geothermal resources have important strategic value for New Zealand, as they are able to directly supply both heat and electricity (see “New Zealand Geothermal Industry Is Poised for the Future” in this

Brine, the waste stream of the geothermal power production cycle, is usually considered a nuisance. High in corrosive minerals, even when reinjected, it’s challenging to manage. So when Simbol Inc. showed it had a way to turn this waste stream into a revenue stream by mining it for high-value minerals like lithium, a lot of […]

Water and energy are intimately linked. Water is necessary for the production, distribution, and use of energy. Energy is needed for the withdrawal and delivery of water. The two are inseparable. Several
