Assemblymember Jones-Sawyer tour of Nant de Drance Pumped Storage Project

Assemblymember Jones-Sawyer touring the Nant de Drance Pumped Storage Project, the  largest underground energy storing plant in Geneva, Switzerland. It cost $2 billion and they plan a Return on Investment in 80 years.  It's taken 10 years to build and opens in 2020.
NANT DE DRANTZ.

Nestled in the heart of the Alps, the Swiss are building one of the world’s most advanced pumped storage hydropower projects: Nant de Drantz. Once completed, the 900 MW facility will feature six variable-speed turbines that can change their power output to more precisely serve system needs. These two-way turbines can both produce electricity as the water flows down from the upper reservoir and, conversely, act as a super high capacity pump to move water back up from the lower reservoir. This impressive feat of engineering is more than just another energy project, it’s vital infrastructure that will play a pivotal role in intercountry electricity grid incorporating increasing levels of variable renewable energy.
