Summary: We develop a lead-time quotation model for a Make-To-Order production or service system with risk-averse customers. By analyzing customers' decisions and the optimization problems of the provider and social optimizer, we study dynamic and single lead-time quotation policies and identify the optimal entrance thresholds. The research shows that the detrimental effects of risk aversion can be addressed more efficiently for the provider's problem compared to the social optimizer's one.

Summary: This paper investigates the obstacles that prevent companies from flexibly adjusting their power consumption, including economic, regulatory, technological, organizational, behavioral, informational, and competence obstacles. The study combines a structured literature analysis and a case study, finding that technical risk, lacking revenues, and low cost savings are the main reasons why companies do not flexibilize their power consumption.

Summary: The increasing use of volatile renewable energy sources poses challenges in balancing supply and demand. Therefore, demand-side flexibility becomes more important for system operators and balancing authorities. This paper proposes a set of novel flexibility management methods for ventilation systems, aiming to integrate them into the flexibility service.

Summary: This paper establishes and tests a model of buyer-supplier relational investment that connects supply chain integration (SCI) with supplier flexibility performance (SFLEX) advantages in various manufacturing environments. It finds that social exchange investments in relationship stability and information quality fully mediate the positive performance relationship between supply chain integration and supplier flexibility performance. However, the relative importance of different forms of investment in enhancing supplier flexibility performance varies depending on the manufacturer's order fulfillment environment.

Summary: A randomized field experiment compared the household consumer welfare effects of reacting to dynamic electricity price incentives and time of use incentives. The study found that dynamic incentives only induced half the change in electricity consumption compared to time of use incentives. This suggests that a combination of time of use and dynamic pricing incentives is likely the optimal tariff structure for balancing demand flexibility and consumer welfare costs.

Summary: The buildings sector can provide important demand-side flexibility for renewable energy integration. A normalized and parameterized model is dispatched to evaluate the potential revenues obtained from providing grid services. The results show regional and seasonal differences in the flexibility value of building load shifting, suggesting the need for different demand response program designs and business models based on building technologies and grid environments.

Summary: This paper provides a comprehensive analysis and assessment of power flexibility from HVAC loads in U.S. commercial buildings. It reveals that cooling loads in commercial buildings offer more flexibility for increasing power consumption than for decreasing it, with potential for a significant increase and decrease in power consumption on peak summer days.

Summary: The decarbonisation of heat supply is crucial for emissions reduction, but there is uncertainty about achievable levels and optimal technology mix, which can impact future electricity and gas demand. This study uses an integrated model to quantify the impacts of heat decarbonisation on future electricity and gas demand, with a case study in Great Britain. The results show that electrified heat supply leads to a volatile electricity demand, while hydrogen-based heat supply reduces peak gas demand and shifts seasonality towards electricity. Sensitivity analysis highlights the importance of relative heat demand and performance of heat pumps. Demand-side flexibility can help balance the electricity system and minimize infrastructure requirements. The findings have relevance for global energy transition.

Summary: The study highlights the high potential of Demand-Response (DR) in power systems planning, which helps delay future investment in power capacity and reduce CO2 emissions. However, the limited potential of DR to integrate additional renewable plants and uncertainties related to future weather conditions need to be emphasized.
