Load-Shifting Strategies for Cost-Effective Emission Reductions at Wastewater Facilities

In this talk, Fletcher will discuss how energy flexibility can help reduce Scope 2 emissions of wastewater treatment facilities. Using a facility from the Bay Area as a case study, he investigates three load shifting mechanisms: a raw wastewater storage tank, a low-pressure biogas holder, and a Li-ion battery. Simulating operations using a data-driven model demonstrates how cost-optimal and emissions-optimal operation vary widely, and as a result the cost of carbon used when co-optimizing has a large impact on the resulting operation.
