R&D and D Continuous improvement
• In 40 years, from 70 to 80% cycle efficiency • Availability, Reliability, Cycling • Very High or Very Low Head (<50m & >800m)
More challenging sites
• Head range increase • Underground reservoir • Sea water operation • Variable Speed offering - New Plants: faster – higher power
Flexibility
- Upgrade of existing units • Power range increase to increase capacity reserve • Reaction time reduction
