Growth in energy demand together with the increased volatility from growing intermittent electricity production requires new sources of demand flexibility to maintain power system balance. End-use specific curtailable electricity contracts are one incentive-based Demand Response (DR) instrument that could help increase flexibility. This paper employs a choice experiment on a representative sample of electricity consumers in Ireland to elicit their preferences for these types of contracts on household appliances during peak load hours. A welfare analysis is then conducted to determine the compensating variation for different contract scenarios and examine the potential savings associated with a selection of scenarios from the perspective of the power system. The results suggest that there could be potential for flexibility from curtailable electricity contracts. On average, consumers are found to be mostly indifferent to curtailable contracts compared to their status quo contract. More specifically, the type of household appliance in these contracts has the most influence on preferences, while contracts at low event frequencies that include advance notice and an opt out are most preferred. In general, the net benefits to the system in curtailing the tumble dryer or dishwasher at low monthly frequencies are found to be positive, while net benefits are estimated to be negative for the other appliances.

能源需求的增长以及间歇性电力生产不断增加的波动性需要新的需求灵活性来源来维持电力系统平衡。最终用途特定的可削减电力合同是一种基于激励的需求响应 (DR) 工具，可以帮助提高灵活性。本文对爱尔兰电力消费者的代表性样本进行了选择实验，以了解他们在高峰负荷时段对这些类型的家用电器合同的偏好。然后进行福利分析以确定不同合同情景的补偿变化，并从电力系统的角度检查与选择情景相关的潜在节约。结果表明，可缩减电力合同可能具有灵活性。平均而言，与现状合同相比，消费者对可缩减合同大多无动于衷。更具体地说，这些合同中的家用电器类型对偏好的影响最大，而包括提前通知和选择退出的低事件频率的合同是最受欢迎的。一般而言，系统在减少每月频率较低的滚筒式干衣机或洗碗机方面的净收益是正的，而其他设备的净收益估计是负的。这些合同中的家用电器类型对偏好的影响最大，而包括提前通知和选择退出的低事件频率的合同是最受青睐的。一般而言，系统在减少每月频率较低的滚筒式干衣机或洗碗机方面的净收益是正的，而其他设备的净收益估计是负的。这些合同中的家用电器类型对偏好的影响最大，而包括提前通知和选择退出的低事件频率的合同是最受青睐的。一般而言，系统在减少每月频率较低的滚筒式干衣机或洗碗机方面的净收益是正的，而其他设备的净收益估计是负的。
