Need for Change: Industry Challenge
Investor-Owned Utility legacy model
No innovation for decades
Guaranteed rate of return on invested capital Not incentivized to be capital efficient Regulators focused on rates, not operations Industry counts on Feds to support R&D Repels private venture capital Utilities spend nearly $0 on R&D
Need to be transformed like Telecom
Changes in regulation brought new era of change and fueled innovation for consumers

Utilities need Energy Storage ► Industry builds grid infrastructure to meet peak demand
Renewables mandated need storage – intermittency Distributed deployment maximizes benefits – T&D Supply & demand mismatch – seasonal peaking Load growth exceeding distribution system capacity Lower generation World Load Growth Q BTU fleet capacity factors < 45% utilization Source EIA
