1. US Army Corps of Engineers BUILDING STRONG ® Greg Mellema Hydropower Master Plan (HMP) Operations Division Omaha District 08 Dec 2015

2. BUILDING STRONG ® Purpose: Develop a strategic master plan that will guide future programming and funding for all hydropower sustainment, rehabilitation, and modernization requirements in a way that provides predictable funding and maximizes efficiencies to ensure that long-term resilience and reliability of this critical National infrastructure. End State: Omaha District hydro-power infrastructure is rehabilitated and modernized no later than CY2035 in order to maximize resilience and provide renewable, reliable energy production to the Nation for an additional 50 years. Commander’s Intent 2

3. BUILDING STRONG ® 3 HMP SCOPE Definition: This project will create a master plan for Missouri River Hydropower plants capital improvement program. Justification: WSPC is interested in funding capital improvements to maintain reliability at USACE run hydropower plants. A master plan will guide the long range sustainable development of USACE facilities by providing a coordinated framework to plan, program, and execute project that fully support the district and division mission.

7. BUILDING STRONG ® Hydropower Master Plan DRAFT Development Goals  PLAN- Develop a comprehensive, feasible, and efficient master plan.  PROGRAM – Program and secure predictable funding for sustainment, rehabilitation, and modernization of power plant infrastructure IAW master planning framework.  PRIORITIZE – Set and adjust priorities of work through risk-informed decisions and communication.  EXECUTE- Complete all programmed and funded work IAW established contracts and agreements. These goals form the foundation for our deliberate planning process… 5

8. BUILDING STRONG ® Operation Project Manager Input LocationHMP Recommendations Big Bend (K. Fink) Last 10 years we have removed low hanging fruit Foresee bigger projects, prior there was no available funding Fear, decisions going away from OPMs Don’t peanut butter spread $$$, highest need first OD walk through plant identifying future requirements Fort Randall (T. Curran) Utilize 60 years worth of data to D-B replacement components How to get more energy with the given water Plan needs to comprehensive without regards to funding stream Risk Management what data is need to determine risk? P3, not a good idea Oahe (E. Stasch) Biggest issue, regulations and trying to meet perfection is not possible Plan needs to be overarching 30K ft view of requirements rather than project specific Need to keep commonality between projects Needs to be useful format, rather than 3” thick Take in consideration future security requirements
