- ERCOT Distributed Generation and Demand Response in ERCOT
Audio Description (Extended) Script
Narrator: ERCOT relies on all generation resources to help meet demand on the electric system.
0:06 (Extended): Five graphics appear: a power plant, solar panels, a windmill, a battery source with electric towers, and a power wall.
Narrator: Distributed Generation, or DG, refers to smaller power systems connected at the distribution level that can supply power to the grid when needed.
There are three types of DGs in ERCOT. Unregistered DGs are mostly rooftop solar systems owned by residential customers.
0:24 (Extended): A sequence of text phrases appears:
“Typically less than 1 megawatt.”
“Not registered with ERCOT.” and
“Not compensated by ERCOT.”
Narrator: These systems are connected to the electric grid, but not all of them actually push power onto the grid. Settlement-Only DGs are often supplemental generation resources located at businesses where they can provide backup power during outages.
0:39 (Extended): Text appears, “Each unit is typically less than 10 megawatts.”
Narrator: These resources are registered with ERCOT and compensated for the energy that they export to the grid, but they are dispatched by the resource owner. Distribution Generation Resources are typically standalone resources.
0:52 (Extended): A dashed line flows through graphics of three side-by-side battery sources.
Narrator: Similar to SODGs, they are registered with ERCOT and compensated for their energy, but they are dispatched by ERCOT…
0:59 (Extended): A sequence of text phrases appears:
“Compensated and dispatched by ERCOT for energy and additional services.” and
“Each unit is typically less than 10 megawatts.”
Narrator: …and can also be compensated for providing additional services, such as reserve power.
Demand Response, or DR, refers to lowering electric load when grid conditions are tight. ERCOT’s markets allow participation by industrial and commercial customers who agree to reduce their load when needed. Electric providers may also implement their own load reduction programs…
1:23 (Extended): A graphic of an ERCOT home thermostat appears, showing the temperature setting adjusting from 74 to 80 degrees.
Narrator: …and certain customers may voluntarily reduce their demand in response to higher energy prices.
By using all of these techniques, ERCOT is able to operate a reliable electric grid for the people of Texas.
