Turbine Hill Chart: How to Read It (and Dispatch Well Without One)

The hill chart is the map every dispatch decision walks over. Most operators have never been shown how to read it against a market price, and many plants no longer have a reliable one at all. Here is what the chart says, what it hides, and what to do when yours is missing.

What it maps

Efficiency vs unit flow and unit speed

What it hides

Damage, cavitation and start-stop cost

Reference result

+7.82% net uplift, 300 MW Francis unit

90-Day SMARD Backtest: Revenue Uplift From DP Dispatch, With Wear Explicitly Priced

A 90-day SMARD-backed backtest shows where dynamic programming created measurable revenue uplift versus a naive top-price-hours baseline, and where the current wear-aware stochastic configuration still needs tuning.

Dataset

SMARD DE-LU, 90 days

DP revenue signal

+€3.93M (+178.96%)

Wear result

No reduction observed

Francis Turbine Cavitation: Quantifying Wear Cost and Optimizing the Operating Point

Cavitation in a Francis unit is not just a maintenance defect. It is an operating cost that should be priced into dispatch when the unit moves away from BEP or into low-sigma hillchart zones.

Hydraulic signal

Sigma margin and Hn

Mechanical signal

von Mises stress cycles

Decision metric

Revenue minus wear cost

Cavitation Damage in Francis Turbines: How to Quantify Wear Cost and Optimize Your Operating Point

Cavitation damage in a Francis turbine is not only a maintenance issue. It is a dispatch cost. If the operating point drifts into low-sigma, off-BEP zones, the plant may gain short-term megawatt-hours while quietly destroying runner life and margin.

Damage signal

Sigma margin and BEP distance

Cost metric

EUR/hour wear penalty

Decision rule

Revenue uplift minus damage cost

Pumped-Storage Optimization: Maximize Arbitrage Revenue with Dynamic Programming

For pumped-storage fleets in France and Switzerland, the real arbitrage value does not come from a simple spread rule. It comes from a state-aware schedule that combines EPEX Spot prices, reservoir dynamics, turbine efficiency, and dynamic programming.

Target market

France + Switzerland

Core method

Dynamic programming

Typical uplift

8-15% vs. naive scheduling

Pumped-Storage Optimization: Maximizing Arbitrage Revenue with Dynamic Programming

Pumped-storage arbitrage is no longer about a simple buy-low, sell-high rule. The highest-value schedules combine EPEX Spot spreads, reservoir trajectories, turbine operating points, and state-aware optimization.

Target market

CH / DE / AT

Core method

Dynamic programming

Typical uplift

8-15% vs. naive planning

Pumped-Storage Hydro Scheduling: Maximize Arbitrage Revenue with Dynamic Programming

For pumped-storage operators and energy trading desks, the real edge is not spotting a single high spread. It is scheduling the whole reservoir trajectory, mode changes, and hourly loading so EPEX Spot volatility becomes repeatable arbitrage revenue.

Target market

EPEX Spot day-ahead + intraday

Core method

Hydro scheduling dynamic programming

Typical uplift

8-15% vs naive scheduling

Hydro Power Optimization with Dynamic Programming — More Revenue, Less Wear

Hydropower optimization is no longer just a static efficiency problem. The best dispatch blends hill charts, reservoir value, EPEX Spot prices, balancing markets, and turbine wear.

Core method

Dynamic programming

Market signals

EPEX Spot + aFRR/mFRR

Typical uplift

5-15% per turbine/year

Pumped-Storage Hydro: How to Maximize Arbitrage Revenue with Optimal Dispatch

Pumped-storage operators do not earn their margin by simply pumping at night and generating in the morning. The value comes from choosing the right hours, reservoir trajectories, and unit loading across EPEX Spot day-ahead and intraday markets.

Core market

EPEX Spot + ENTSO-E

Main problem

Day-ahead and intraday dispatch

Typical upside

5-15% uplift per turbine
