NYSERDA New York State Energy Research Development

This commitment is the largest renewable energy procurement by a state in U.S. history. These projects, which total 1,696 megawatts, are enough to power more than 1 million New York homes and support more than 1,600 jobs while advancing progress toward Governor Andrew M. Cuomo's newly enacted offshore wind target of 9,000 megawatts by 2035.

High Pressure Grinding Rolls (HPGR) Mining SGS

High Pressure Grinding Rolls (HPGR) is a mature technology that is proven to reduce capital and operating costs in full scale plants when compared to other comminution technologies. The use of a small locked-cycle scale test, such as the Bond ball mill grindability test, was proposed as an alternative way to achieve the same objective in a more controlled manner, and more importantly, with a smaller sample.
