RiverBasinObject: Powerhouse (hydropower)

• power head (vertical distance between storage level of the reservoir and the altitude of the powerhouse and its turbines;
• flow of water to the powerhouse and thus over the turbines;
• the associated economics of power generation.

The primary information relates to location (including vertical position relative to the dam), extent and water provided; please note that a powerhouse does not include any consumptive use, i.e., inflow - outflow.

They are primarily described by their HEADER and the hypertext description and imagery.

Attributes are grouped into topics and shown in pop-up windows that are triggered by BUTTONS.
They include:

1. Admin owner/operators;
2. Operations describing the efficiency (turbine type and power head, maximum capacity) and the relation to the dam/resercoir;
3. Demand, water allocated for power production
4. Economics cost and benefit data:
   • investment (annualized)
   • operating costs (monthly and/or per unit water used)
   • benefits per unit electricity generated (may be time-dependent with differences between base- and peak power)
   • penalties for water shortfall (unsatisfied demand, optional)
5. Links to other objects: Please note that a powerhouse can be either
   • linked to a dam/reservoir as a source of water and gradient (power head);
   • or directly between two river reaches, represent an in-stream turbine for run-of-the-river with a minimal head but large flow/volume and the corresponding turbine types.
