Spot Pricing

Definition

Spot Pricing is a highly sophisticated deregulated utility billing model dynamically pegging the explicit financial rate charged to a consumer against the volatile, 15-minute fluctuating baseline commodity cost dictated instantly by the live external energy exchange market.

Business Purpose and Architecture

In extreme deregulated environments, major corporate consumers agree to assume total market volatility risk to attain cheaper absolute energy baselines. Architecturally, the utility no longer defines the active price. Instead, Interval load shapes map through the RTP Interface directly against a parallel ‘Price Profile’ actively synchronized with the energy bourse. Standard formulas internally aggregate the delta—charging the exact market Spot Price for any active load drawn completely above the customer’s predefined stabilized capacity baseline.
