5 Energy & Demand Energy (kwh) Peak Demand Energy is a measure of the amount of power (kw) consumed over a specific period of time (in this case, hours) Demand (kw) Demand (kw) Demand corresponds to instantaneous power (kw) consumed and is typically measured as the average of a 15 minute period Time Energy (hours) Time Slide 5

40 Engage With Financiers Does your existing financier provide solar + storage finance solutions? If not, engage with Geli to determine best fit finance solution Slide 40

41 Re-run Project Economics Just as with a solar PV project, you must consider how the cost of project finance will affect nomoney-down options Slide 41

42 PPA 2.0 Present the Business Case Slide 42

43 Selling the Customer Savings should be meaningful Hedge against rising demand charges Previous solar + storage or energy storage experience preferred, but not required Backup power can be more attractive than savings Existing relationships are key Protect against potential large additions to load Slide 43
