1 GridWise Architecture Council RATES Retail Automated Transactive Energy System Transactive Energy In Real Life! June 13-15, Portland, Oregon Michel Kohanim CEO Universal Devices, Inc.

2 About RATES (Retail Automated Transactive Energy System) Funded by California Energy Commission, with support from Southern California Edison and the California ISO Implementation of Transactive Energy in its purest form Perfect example of the near-future building: off-the-shelf devices, DER, Smart Meter, automation/energy management, and even AI assistants Joint project of Universal Devices, Inc. and TeMix Inc. Will be installed in up to 200 SCE residential and SMB First installation was done in May of It s beautiful! 2

4 Transactive Energy Is Not: Prices to Devices Grid instability since most devices buy/sell at around the same time Difficult to recover fixed/variable costs for parties Bids/Offers without binding delivery and payment commitments Very difficult for settlement between parties Very difficult for grid operators to forecast response Requires estimated baselines and measurement/verification 4

5 Transactive Energy Is: Transactions at specific locations and time intervals Energy related products such as Real and Reactive Power Transport related products such as two-way energy transport Full lifecycle Tender (or offer), transaction, and delivery Bi-directional: in case of selling what was previously purchased and/or excess DER generation Settlement does not require measurement/verification Tariffs can be implemented using Transactive Energy 5

6 RATES Retail Tariff Forward transactions & subscriptions with spot transactions Subscribe at specific costs and quantity for each interval Easily automated using subscriptions, positions, and goals Buy more at spot prices if necessary Sell at spot prices if desired Shed/shift load and/or DER Two-way transport tariff recovers more fixed costs at higher prices when circuit is more heavily loaded in either direction Solves Bill, revenue, and grid volatility issues with prices to devices (bids/offers) Recovery of both fixed and variable costs for all parties 6

7 RATES Helps DER! Voltage depends on Real & Reactive Energy/Power flows Just like Real, Reactive is an Energy product that can be transacted using Transactive Energy Forward Transactions and Subscriptions Make DER revenues stable Optimize the operation of DER 7
