Ultra-low Partial Discharge - Comparison of New and Old HV Winding Electrical Insulation Performance
How ASI Marine Protects Hydropower from Invasive Mussels
The Advisory Council on Historic Preservation's (ACHP) Anticipated Regulatory Changes and Likely Effects for Hydro Developers/Licensees
Ultra-low Partial Discharge - Comparison of New and Old HV Winding Electrical Insulation Performance
presented by Arwyn Thomas, PhD, Preformed Windings, and Ratanak So, PhD, U.S. Army Corps of Engineers
This presentation provides insights into the development of ultra-low partial discharge insulation systems to increase the life of hydro generators and improve reliability. It provides direct comparisons of new and old windings from the Chief Joseph facility.
How ASI Marine Protects Hydropower from Invasive Mussels
presented by Dan Butts, ASI Marine
Zebra, Quagga, and now Golden mussel are already moving through North American waterways, finding intakes, penstocks, and fire protection systems before most hydropower operators have a program in place. Drawing on nearly 40 years managing invasive mussel programs, ASI Marine lays out a proven Risk Assessment, Monitor, Control framework built to keep hydropower assets running.
The audience will walk away with three things:
-- 1. Certainty that mussel infestation is a matter of when, not if
-- 2. A repeatable framework of: Risk Assessment, Monitor, Control, for getting ahead of it
-- 3. Proof, at scale, that the framework holds up on a real hydropower asset
The Advisory Council on Historic Preservation's (ACHP) Anticipated Regulatory Changes and Likely Effects for Hydro Developers/Licensees
presented by Troutman Pepper Locke
This presentation focuses on anticipated changes to the Advisory Council on Historic Preservation's regulations governing consultation under section 106 of the National Historic Preservation Act. The audience will benefit from hearing about how these proposed changes, which are expected to be significant and far-reaching, will affect hydropower facilities, including the consultation process required for license amendments and relicensing actions.
