“…Uncertainty is also a concern in the recent work of Alqahtani and Patino-Echeverri (2019). These researchers study how uncertainty about whether "business-as-usual" conditions will prevail and the extent to which buildings will comply with energy codes greatly affects the extent to which there will be cost savings and carbon dioxide emission reductions from the large increase in residential rooftop PV system installations in the Carolinas.…”

“…The previous works [21,22] show that the combination of sizable electricity generation capacity from inflexible base-load NPPs and the limited ramping capability of gas and coal-fired power plants set the penetration limit of rooftop solar PV systems to about 9% (10.8 GW). Here, we examine the economic and the environment merits of the power system when the penetration limit of rooftop solar PV systems and the flexibility of NPPs are increased.…”

This paper estimates the maximum integration level of residential rooftop solar photovoltaic (PV) capacity within the power network of the Duke Energy Progress (DEP) and Duke Energy Carolinas (DEC) under two scenarios embodying different assumptions about the flexibility of nuclear power plant (NPP) operations. A mixed-integer optimization model was constructed and simulated to find out the maximum solar penetration level under each scenario and to calculate the expected total system’s electricity generation costs, energy mix, atmospheric emission reductions, and emission abatement costs. Analysis reveals that improving NPP operation maneuverability would increase the maximum solar PV penetration level in the DEP and DEC power networks by 39%, from 8.9% to 12.4% of the total system’s electricity generation. Consequently, it would further improve the electricity generations’ unit costs and CO2 emission reductions by 3% and 8% points, respectively. On the other hand, increasing the solar PV penetration limit under high flexible NPP operation scenario leads to increase in the CO2 emission abatement costs by 8% points. The results of the study indicate that the flexibility of existing power system resources may present a barrier for a large uptake of solar energy.

“…The relationship between different income levels and solar uptake in Australia is analyzed in [10], thereby bringing out a case for detailed study of socio-economic indicators for policy updates. In [11]- [12], reduction in 2 emissions by upgrading all households to comply with energy star standards combined with increased roof-top solar PV installations and optimization for net zero energy homes are addressed. A case-study of a PV agricultural business model is presented in [13] in which greenhouses with rooftop PVs generate revenue from PV generation whereas the greenhouse space is leased out to agricultural ventures thus creating a complete entrepreneurial ecosystem.…”

Background Domestic solar PV installations in India are yet to become a valuable proposition for both the prosumers and utility because of the deficiencies in the formulation of the policy parameters. This paper presents a comprehensive analysis of the consumer-centric business model for rooftop solar PV installations in India. We explore areas where potential policy interventions may be introduced to improve collective stakeholder benefits and incentivize more domestic consumers to install rooftop solar panels in their premises. We propose a policy framework that seeks optimal Feed-in Tariff (FiT) rates, PV capacities and Average Billing Rates (ABRs) towards maximizing stakeholder benefits. The stakeholders considered are the consumers/prosumers and the utility. Results Case studies with three residential prosumers of different demand and generation profiles (extracted from data provided by Indian utilities) are presented. A multi-objective problem is formulated with the FiT, generation capacity (as a function of demand) and ABR as decision variables, exploring the various welfare trade-offs. The pareto-optimal front is identified for prosumer and utility benefits and suitable points with reasonable tradeoff are selected based on sensitivity analysis of the impact of the decision variables on collective welfare. Conclusions The paper provides a workflow to fix tariff, FiT and local PV capacities in active residential distribution systems. The suitability of prevailing tariff and FiT rates of three Indian utilities namely, MSEDCL, TATA POWER (Delhi) and TANGEDCO are studied, and their impact on prosumer savings and utility profits is brought out. The paper recommends optimal installation capacities for prosumers based on their load demand so as to encourage the adoption of roof-top solar without affecting collective benefits. This provides policymakers and prosumers an effective decision-making tool.
