RiverBasinObject: Powerhouse (hydropower)
A Powerhouse is associated with a dam/reservoir
object and describes the generation of hydropower as a function of
- 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.
- Admin owner/operators;
- Operations describing the efficiency (turbine type and power head, maximum capacity)
and the relation to the dam/resercoir;
- Demand, water allocated for power production
- 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)
- 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.
