Hourtoule, Electricity contract: scope and forecasted consumption, 16/07/2015 © ITER Organization It will take about 3 years to implement the full transition form the present (CEA Cadarache) to the future point of delivery (400 kV grid). Therefore, the historical consumption data cannot be used to forecast the consumption during the coming 2 years. Transition from present to future point of delivery

Page 24J. Hourtoule, Electricity contract: scope and forecasted consumption, 16/07/2015 © ITER Organization During the ITER Project construction phase, the consumption will increase. The variation of power (and energy) demand can be reasonable predicted. Vice versa, there are significant uncertainties on the start-up date of each main consumer. Forecasting accuracy: main uncertainty

Page 25J. Hourtoule, Electricity contract: scope and forecasted consumption, 16/07/2015 © ITER Organization The test and commissioning of the Cryoplant implies the 24h/day, 7days/week operation of some high power (5 MW) compressors. The starting date for the test will be planned some months in advance. But, the actual scenario will be quite different. Forecasting accuracy: example

Page 26J. Hourtoule, Electricity contract: scope and forecasted consumption, 16/07/2015 © ITER Organization In case it is economically viable for the ITER Organization: The ITER Organization can regularly communicate to the electricity supplier (example every month) the forecasted consumption. However, during the testing and commissioning phase, there could be up to 2-4 months uncertainty on the actual starting date of the consumption. The ITER Organization can promptly communicate to the electricity supplier any unexpected event (example a plant fault), which has a significant impact on the forecasted electricity consumption. The ITER Organization is interested in reward schemes for peak shaving capacity. Routine forecasting, anticipated changes and peak power shaving

Page 27J. Hourtoule, Electricity contract: scope and forecasted consumption, 16/07/2015 © ITER Organization Contracts scope includes both the supply of electricity and the service of Balance Responsibility Entity. The initial contract will be for 1 year with two options to extend the contract by a further year, giving a maximum total of 3 years for the duration of the contract. Although the forecasted consumption is relatively low (0.3 MW, 4 GWh/year), in 2018 is expected to increase up to (20 MW, 80 GWh/year). The electricity consumption will further increase during the following years (new call for tender will be launched). The variation of power (and energy) demand can be reasonably predicted. Vice versa, there are significant uncertainties on the start-up date of each main consumer. The ITER Organization can communicate to the electricity supplier (example every month) the forecasted consumption. There could be up to 3-4 months uncertainty on the actual starting date of the consumption. The ITER Organization is interested in reward schemes for peak shaving capacity. Conclusions
