Cross-Border Hydro Planning

Cross-Border Hydro Planning

Huge floods that have swept through Central Europe have pushed hydropower development and its role in managing water flows to the top of the political agenda.
Replacing an Aged Woodstave Penstock

Replacing an Aged Woodstave Penstock

The 40-plus-year-old penstock supplying water to the 29-MW Rocky River pumped-storage plant was replaced with a smaller-diameter pipe that actually increases water flow to the plant, boosting power generation.
Pricing German Power Positively

Pricing German Power Positively

Pigs haven't yet flown when the wind blows hard in Germany, but when considering unlikely scenarios, prices on the wholesale day-ahead spot market for electricity have plummeted to -500&€/MWh, while more than 700 km to the south, water flows uphill in the Austrian Alps.
Brazil’s Drought Brings Water Supply to Near Zero Capacity at Hydroelectric Facilities

Brazil’s Drought Brings Water Supply to Near Zero Capacity at Hydroelectric Facilities

Brazil is experiencing a debilitating drought as the nation endures the driest period since South America’s most populous country began keeping records in the 1930s. As a result of the arid conditions, reservoir levels and lake water flow to hydroelectric facilities that supply power to Brazil’s most densely populated city of Sao Paulo are nearing zero capacity.
