Project Status

Project Result

The CPRs #3 were conducted. The team continues to evaluate data for both sub projects and has requested a 3 month extension due to COVID related delays on the water side of the project. The refrigeration team is also working with CEC staff to discuss participation in a refrigeration workshop planned for the summer.

The Issue

During periods of peak electrical usage, matching supply and demand for the electric power grid has become increasingly challenging due to increasing penetration of variable renewables into the supply mix. Demand response (DR) provides an opportunity to mitigate grid instability and the high cost of purchasing electricity at critical times. California's industrial sector has the potential to provide fast and flexible DR through the development of control strategies.

Project Innovation

The project develops technologies with the potential to achieve at least 20% demand reduction or adjustment for fast and flexible demand response (DR). The pilot demonstrations are at 2 different end use sectors: 1) a water pumping station and 2) commercial refrigerated food warehouse. The control strategies demonstrated can be replicated to show plant managers a way to integrate control strategies to reduce and adjust demand, to achieve new levels of operational reliability and efficiency.

Project Benefits

This project develops technology that will enable industrial customers to provide automated DR service to the grid including fast ramping, operating reserves, frequency regulation, and peak load reduction in support of California's goals for DR and energy efficiency as well as renewable integration and greenhouse gas emissions reduction. For refrigerated warehouses, the ability to shed load during periods of grid stress will be important, especially during summer heat waves like those experienced in 2020.

Lower Costs

Affordability

The project has the potential to reduce demand for a variety of grid use cases including fast ramping, operating reserves, frequency regulation, and peak load reduction. This can result in lower demand charges and energy costs to the customer.

Greater Reliability

Reliability

Supporting fast and flexible demand response helps to augment power system reliability and results in less stress on the grid by reducing peak loads. These services can help with maintaining system reliability.
