Welcome to Ramm Power Group

At Ramm Power Group, we’re developing sustainable, pumped hydro power storage systems that transforms clean, carbon-free renewable energy into continuous, reliable dispatchable peak power. We’re currently working on several projects, including the Sacaton Energy Storage Project in Arizona near Casa Grande.


On January 15, 2020, Ramm filed the notice of intent (NOI) and pre-application document (PAD) with the Federal Energy Regulatory Commission (FERC) for its Sacaton project using the Commission’s Traditional Licensing Process (TLP). The company has also successfully sourced the required funding to construct its Pumped Storage Hydro (PSH) power storage facility on the retired Asarco copper mine site near Casa Grande, Arizona just south of the greater Phoenix metropolitan area. Read the press release.


Section 21, 16 U.S.C. § 814 (2012) provides Ramm Power Group a unique opportunity to acquire the requisite land required to build the Sacaton Pumped Hydro Storage facility. Therefore, any considerations for utilizing the Sacaton project for other commercial opportunities will be secondary to those of Ramm once a Federal Energy Regulatory License is granted.
