Village power plant profitable energy storage

How much energy does the village use?

The total load of the village is estimated to be 975.52 kWh/day, (see Table 3), and accordingly a PV system has been designed/sized. The major energy consumption of 928.50 kWh/d is related to domestic home requirements while the medical center and the school account only for 6.84 kWh/d and 8.42 kWh/d of the energy.

What is zero energy village?

The concept of zero energy villages is to install grid connected PV system without battery backup according to the power requirements. During the peak sunshine hours the electricity can be distributed to the consumers and any excess power can be fed to the grid. During cloudy or winter season the consumers can get the energy from the grid.

Can a PV system fulfill the load demands of a village?

In this study, RETScreen model is used to investigate the optimal design options and the techno-economic viability of the PV system to fulfill the load demands of a village in Pakistan. The studied village has small load demands which is estimated based on facility type.

How does solar power work at Donoussa Island?

The installed stand-alone plant at Donoussa Island has the PV field as the sole energy source. The micro-hydraulic system of the plant is used for energy storage. The intermittent nature of solar radiation does not guarantee the uninterrupted power supply.

What is the economic feasibility of the proposed energy system?

The analysis of the proposed system is carried out based on its energy production capacity and economic viability. The economic feasibility of the system is evaluated by comparing it with grid supplied electricity at a rate of 0.15 US$/kWh.
