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 project in Arizona near Casa Grande.


On January 15, 2020, Ramm filed the paperwork for a Federal Energy Regulatory Commission (FERC) license which includes the notice of intent (NOI) and pre-application document (PAD) for its Sacaton project (formerly Sacaton mine or ASARCO) 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.

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.


Ramm Power Group is a proud member of the Energy Storage Association (ESA).
