The REopt™ Lite web tool allows users to:

  • Evaluate the economic viability of distributed PV, wind, battery storage, 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
