This paper describes the technical-economic analysis of a hybrid renewable energy systems (HRES) connected to the grid, consisting of photovoltaic (PV) source and municipal solid waste (MSW), taking into account economic and technical criteria. Photovoltaic energy and the new technology used for MSW processing have a lower cost and lower environmental impact. The sensitivity analysis shows that improving the rate of return on investment in HRES can be a measure to encourage the use of renewable energies for electricity production, both in terms of costs and environmental impact.

Hybrid Renewable Energy

Nigeria has great renewable energy resource potential comprising solar, wind, biomass and hydro and much work has been done on estimation of this potential. Variability of a single resource type, high cost of energy from renewable sources and impracticability of grid extension to distant rural areas from the national grid has led to the development of hybrid renewable energy systems (HRES). Although Nigeria is rich in these renewable resources, a hybrid application approach seems more feasible to ensure a reliable and cost-effective power supply from these sources. This study was conducted to assess Nigeria’s technological readiness for adopting HRES, its environmental impact and its viability over a 20-year period. A review of past literature was carried out to ascertain the country’s readiness for HRES and its environmental impact, while the discounted cash flow (DCF) analysis, along with other economic indicators of net present value (NPV), internal rate of return (IRR) and payout period (PO) were adopted to estimate the economic viability of the system. The outcome of this paper shows that HRES for power generation in Nigeria is economically viable.

Innovative Solution

Smart energy system is one of the important infrastructures for building smart city. Waste to energy (WtE) is an innovative solution using municipal solid waste (MSW) as a source for electricity. This research was conducted to design WtE Plant in Depok and to asses economic viability of different business models. The technologies applied in WtE are anaerobic digestion and gas engine to generate electricity. The simulation was conducted using SuperPro Designer and UniSim Design software to evaluate the technical performances of electricity production from organic solid waste. The feasibility of project implementation of various business models are evaluated through economic analysis. The result of this study shows that the organic fraction of municipal solid waste in Depok has potential to generate electricity up to 28 MW. From economic aspect, pay off business scheme greatly affects the value of NPV and IRR. Meanwhile, the intervention scheme on fiscal incentives and low loan interest rate have slight effect on IRR values. A combination of Viability Gap Fund (VGF) and increased tipping fees intervention scheme is an optimum business scheme to build WtE plant and achieve electricity price below the offtaker’s willingness-to-pay.

Hybrid Renewable Energy

This paper presents eight hybrid renewable energy (RE) systems that are derived from solar, wind and biomass, with energy storage, to meet the energy demands of an average household in the six geopolitical zones of Nigeria. The resource assessments show that the solar insolation, wind speed (at 30 m hub height) and biomass in the country range, respectively, from 4.38–6.00 kWh/m2/day, 3.74 to 11.04 m/s and 5.709–15.80 kg/household/day. The HOMER software was used to obtain optimal configurations of the eight hybrid energy systems along the six geopolitical zones’ RE resources. The eight optimal systems were further subjected to a multi-criteria decision making (MCDM) analysis, which considers technical, economic, environmental and socio-cultural criteria. The TOPSIS-AHP composite procedure was adopted for the MCDM analysis in order to have more realistic criteria weighting factors. In all the eight techno-economic optimal system configurations considered, the biomass generator-solar PV-battery energy system (GPBES) was the best system for all the geopolitical zones. The best system has the potential of capturing carbon from the atmosphere, an attribute that is desirous for climate change mitigation. The cost of energy (COE) was seen to be within the range of 0.151–0.156 US$/kWh, which is competitive with the existing electricity cost from the national grid, average 0.131 US$/kWh. It is shown that the Federal Government of Nigeria favorable energy policy towards the adoption of biomass-to-electricity systems would make the proposed system very affordable to the rural households.
