JS 433 123 310 -248 Capacity Value Summary of Findings The value of customer adoption of SIS units has been investigated from many perspectives and in many sensitivities in the case study above. The only scenario to show a positive TRC benefit is when generation capacity is valued at $250/kW-yr. The only scenario with a positive PCT benefit was under the PG&E TOU tariff. Two scenarios showed a positive RIM benefit: larger SIS units, and high generation capacity price.
