The REopt® web tool allows users to:
- Evaluate the economic viability of distributed PV, wind, battery storage, combined heat and power (CHP), and thermal energy storage
- Identify system sizes and dispatch strategies to minimize energy costs
- Estimate how long a system can sustain critical load during a grid outage.
Step 0: Login and Gather Data
Logging in (optional) enables you to:
save your evaluations
create a custom electricity rate
build a critical load profile
manage typical and critical load profiles
Data needed for a Financial run:
location
electricity rate
load (interval data or building type)
fuel cost (if CHP is modeled)
Data needed for a Resilience run:
critical load assumptions
outage duration
outage start date and time
