What is a Demand Management System?
A demand management system is an innovative technology that lets you automate when major appliances run during on-peak hours to make sure they don't run at the same time. With a demand management system, you can:
- Monitor and control your home's electric load.
- Reduce peak demand costs and help reduce your electric bill.
- Optimize when your home uses energy.
How does Demand Management work in Sighten?
Given a utility has demand charges, when you go to the project phase, then you can turn on demand management for the project in the details. You will be required to enter a kW demand cap. Upon saving, Sighten will automatically smooth your demand during on-peak hours to ensure your demand does not exceed the cap. The Sighten demand model will consider solar, storage and EE enhancements and their impact on demand. If the post project profile can be successfully shifted during peak hours, you will receive a green toast message saying the update was successful. The model does not remove any usage, it just redistributes under the max cap. Thus, it is possible to specify a demand cap that does not that does not allow the demand to be shifted. When a failure occurs, the min required cap will be displayed and the profile will not be updated. You can easily update the max cap, and re-apply the demand management.
Additional Notes
- Demand management is not automatically available for all organizations. If you would like to turn this functionality on for your account, please reach out to support@sighten.io.
- Sighten will need to manually add tariffs to work with the demand management functionality. If you have demand management turned on in your account and you do not see the functionality on a given job, please reach out to support@sighten.io with the utility, tariff name, the job url, and call out the need to use demand management.
