This paper mainly dealt with the technical and economic feasibility of an off-grid hybrid power generation system for a remote rural Turtuk village of Ladakh, located in the northern part of India. The study showed that the proposed configured renewable integrated hybrid system, using Hybrid Optimization of Multiple Energy Resources (HOMER) software, efficiently met the energy demand, exhibiting optimum performance with low investment. The proposed PV(115 kW)/Wind(1 kW)/Battery(164 strings of 6 V each)/DG(50 kW) hybrid system was a highly commendable, feasible solution preferred from a total of 133,156 available solutions resulting from HOMER simulations. The net present cost and energy cost of the proposed configuration were $278,176 and $0.29/kWh, respectively. The proposed hybrid configuration fulfilled local load, with 95.97% reduced dominant harmful carbon dioxide emission, as compared to the sole us of a diesel generator power supply system. The technical performance of the hybrid system was ensured, with advantages including the highest renewable penetration and least unmet load. Furthermore, the analysis exclusively evaluated the impact of the system’s economic parameters (namely, its expected inflation rate, nominal discount rate, and project lifetime) on the net present cost and cost of energy of the system using a noble single fix duo vary approach.

The limited availability of fossil fuels such as coal and increasing air pollution levels due to the burning of coal have pushed the trend of generating electricity from fossil fuels to generating it from locally available renewable resources. It is expected that the cost of electricity will decrease when locally available renewable resources are used. In this paper, it was proposed to commission a solar PV system in a part of an academic building of SRM IST University. The present study is an effort in-line with many initiatives taken up by the Indian Government. The performance index of solar PV system was analyzed. Supporting data were obtained from the NASA PDAV tool and then techno-economical analysis was carried out on HOMER. The average performance ratio and capacity factor of the solar PV system were obtained as 64.49% and 14.90%, respectively. For the optimal configuration, the net present cost and the levelized cost of electricity are $639,981 and $0.34 per kWh, respectively. As per the estimation, there will be no air pollution due to the proposed configuration, whereas if only a diesel generator is commissioned, then 200,417 kg of carbon dioxide will be emitted annually.

This paper presents atechnical and economic analysis of the proposed solar PV/diesel generator smart hybrid power plant for a part of SRM IST, Delhi-NCR campus. The analysis was performed using five battery storage technologies: lead-acid, lithium-ion, vanadium flow, zinc bromide and nickel-iron. The analysis also used the HOMER Pro software. The analysis was conducted to assess performance parameters such as initial cost, simple payback period, return on investment, energy produced, renewable penetration and emission of air pollutants. The optimal solution was obtained as SPP(200 kW)/DG(82 kW)/ZB(2000 kWh), with cycle charging dispatch strategy. The initial cost of this configuration is estimated to be USD163,445, and the operating cost is USD534 per year. The net present cost is estimated to be USD170,348, and the estimated cost of energy with this configuration has been obtained as USD0.090 per kWh. It is estimated that with this optimal solution, the diesel generator may consume only 110 L/year of diesel, which is the minimum of all configurations. Sensitivity analysis was performed between the size of the solar PV array and the size of the battery, along with variations in the battery’s nominal capacity and renewable fraction.

This work intends to perform technical and 2E (economic & environmental) analysis for the proposed hybrid energy generating system for a part load at SRM IST at the Delhi-NCR campus, India. The investigation has been done for electricity generation and hydrogen production through renewable energy sources, mainly solar energy. It is in line with the Indian Government’s initiatives. The proposed hybrid system has to meet the electric load demand of 400 kWh/day with a peak load of 74.27 kW and hydrogen load demand of 10 kg/day with a peak demand of 1.86 kg/h. The analysis has been performed for both on-grid and off-grid conditions. As a result, optimum results have been obtained off-grid condition, with $0.408 per kWh cost of energy, $16.6 per kg cost of hydrogen, low O&M cost ($21,955 per year), a high renewable fraction (99.8%), and low greenhouse emissions (247 kg/year). In addition, sensitivity analysis has been performed between—(1) the solar PV array size & the number of battery strings, with NPC, renewable fraction & CO₂ emissions as sensitivity variables, and (2) reformer capacity & hydrogen tank capacity, with NPC as sensitivity variable.

This chapter focuses on the feasibility analysis and different challenges toward deployment of renewable energy to achieve global sustainability. The analysis emphasizes that the technological advancement, cost, and efficiency are the basic elements for mass adaptation of renewable energy. At the same time, huge available resources, favorable economies, and large social-economic benefits attract major parts of the globe toward the transition from conventional to renewable energy. The proposed chapter also indicates the major options and barriers toward the deployment of different renewable energies in India, which will act as a catalyst to achieve the India’s dream renewable energy target of 175 GW by 2022. In the current era of modern technologies, highly CO2 releasing countries like India and China demand a wide range of renewable energy integration into their power generation portfolios to meet the requirements of global sustainability. Therefore, the proposed chapter will also provide a strong base of energy security for upcoming generations.
