The Lease“The great enemy of clear language is insincerity. When there
is a gap between one’s real and one’s declared aim, one
turns, as it were instinctively, to long words and exhausted
idioms, like a cuttlefish (octopus) squirting out ink”
George Orwell, “Politics and the English Language”

Summary of DER Benefits Customer
– Manage demand– Standby– Lower rates
Utility - Wires Company
– Customer retention– Manage loading
On peak Shutdowns Emergency
Utility - Generation Company
– Energy– Capacity
31
Conclusion
Win – Win (important that utility derive benefits also) Aggregation and Sale can be done through the utility Do not discourage participation with onerous rules and
penalties DER are also important for sticks and wires (not just
generation capacity and energy) Unity power factor at the point of Common Coupling
(DGs to put out vars for voltage and var support also) Utilities need to experiment with DER

Case Study
T&D Substation Expansion $4,000K $400K DR 1 DR Capital Cost $ 880K $ 88K O&M $ 15K $ 15KDR1 Total Cost $ 895K $103K DR2 DR Capital Installation $ 150K $ 15K O&M $ 15K $ 15KDR2 Installation Total Cost $ 165K $ 30K
The installation of the DER is a more economic alternative for the initial deferral of the substation, here again because of having already purchased the DER the saving are even greater.
