Programme overview
Introduction:
Hydropower plant engineering, covering turbines, penstocks, powerhouse and pumped storage, is a 10-day course for plant engineering, powerhouse operations, maintenance and owner's engineering teams, ending with a Hydropower Station Upgrade and Pumped-Storage Operating Plan. Many stations run ageing units away from best efficiency, lose head in neglected waterways and miss the balancing value that solar and wind growth creates. Nominees already operate, maintain or assess hydro units; the first week builds turbine, waterway and control skills, the second adds pumped-storage operation, condition monitoring and refurbishment, taught through inspection walkthroughs. CoreConcept Training Center delivers this hydropower plant engineering course.
Course Objectives:
- Estimate the energy output of a hydropower scheme from net head, flow duration and plant factor data
- Select Pelton, Francis or Kaplan turbines for a site duty using specific speed and hill charts
- Calculate penstock and tunnel head losses and check intake, trashrack, surge tank and powerhouse arrangements
- Set governor, excitation and unit control parameters for stable synchronisation and frequency response
- Assess cavitation, erosion, test and condition monitoring data to plan runner refurbishment and uprating
- Plan pumped-storage operating modes that balance solar and wind output and prepare a Hydropower Station Upgrade and Pumped-Storage Operating Plan
Target Audience:
- Hydropower plant engineering teams responsible for turbine, generator and waterway performance
- Powerhouse operations staff who start, load, synchronise and shut down generating units
- Mechanical and electrical maintenance staff who inspect runners, governors and excitation systems
- Owner's engineering staff who review refurbishment, uprating and new unit proposals
- Pumped-storage scheduling staff who plan pump and generate cycles with the grid operator

Why Attend This Course:
- Deliver a Hydropower Station Upgrade and Pumped-Storage Operating Plan to the station manager and the asset investment committee
- Decide whether a worn runner should be repaired, replaced like for like or uprated to a new hydraulic profile
- Avoid forced outages, cavitation damage and lost grid services caused by units run outside their efficient range
- Brief operators and maintenance crews on governor settings, mode transitions and inspection priorities
Conclusion:
Back at work, the participant gives the station manager and the asset investment committee a Hydropower Station Upgrade and Pumped-Storage Operating Plan for one of the organisation's stations. Managers use it to decide which units to refurbish or uprate first, which governor and excitation settings to revise, and how pumped-storage or flexible units are scheduled against solar and wind output. After the first outage season or scheduling cycle, the unit should compare measured efficiency, availability and forced outages with the plan's targets and update its priorities.
Frequently Asked Questions (FAQ):
What should participants know before a hydropower plant engineering course?
Participants should already work on the operation, maintenance or assessment of hydro units and read basic hydraulic and electrical drawings. Bringing anonymised unit data, test records or an inspection report from their own station makes the walkthrough and case work more useful.
How does hydropower plant engineering differ from a dam safety or general rotating equipment course?
It concentrates on the generating chain: turbines, waterways, governors, generators, powerhouse and pumped-storage operation. Dam safety courses cover structures, spillways and emergency planning, and general rotating equipment courses cover process pumps and compressors, which this course touches only briefly.
Why does pumped storage matter in hydropower plant engineering today?
Pumped storage absorbs surplus solar and wind output by pumping water to an upper reservoir and returns it as generation when demand rises. Its fast ramping, reserve and frequency support make it a practical balancing resource as variable renewable output grows.
What do participants take back from the hydropower plant engineering course?
Participants take back a Hydropower Station Upgrade and Pumped-Storage Operating Plan built on a case station, with a walkthrough checklist, a condition findings ranking, an uprating option comparison and a mode schedule to adapt for their own plant.
