Description

Solar Micro-Grid: To address the issue of electricity in rural communities residing in and around Cairn operational areas in Barmer, Cairn India has established a rural solar mini-grid Solar Pilot Project through its partner, Sun Edison and has provided 500 solar home systems to the community at Barmer • A solar micro-grid involves a centralized solar energy production and storage facility, and T&D lines to connect each household to the central system. Polycrystalline MEMC SunEdison) solar Panels were provided of total capacity: 27kw; the T&D network is spread across as much as 6kms with the potential to service 100 households; along with a high technology Imergy Vanadium Based Flow battery (170kwh) solution with in-built Inverter • A micro-grid provides the benefit of being able to pool the total availability of power due to a central storage facility, hence each household can avail more power. The central facility is easily scalable (through addition of more PV modules) and hence can be easily ramped up. • Post the installation of the PV modules, the ownership of the solar facility was transferred to the Gram Panchayat and will be be run by a Village Electricity Committee (VEC) comprising community members who will be responsible for collecting payments, operations, basic maintenance and security of the facility • Under the micro-grid system, each household is connected to a micro-grid of total 27 Kw capacity, through which they can obtain power for common household appliances such as lights, fans, TV etc. • Each household supplied with 100 feet wires, 2 sockets, 3-4 light points. Socket can be used to charge mobile phones, run TVs, fans and other electrical appliances. Interior wiring and fitting was done by 10 electricians trained at the Cairn Enterprise Centre (CEC) as part of their On-the-Job (OJT) training • The solar micro-grid would support an average household load of 121 watts for 6 hours, that is, on an average 726 watt hour of usable energy would be available on an average for a household. However, micro-grid has the added pooling-in benefit due to the larger central storage, hence there is no fixed limitation on household use; only a limitation on aggregate use. • The battery bank being proposed is large enough (240V, 860 Ah) to provide almost 1 day’s autonomy ie almost 2 days of solar power generation can be stored. In case of scenarios when generation does not take place or is less due to some plant condition or weather, still there will be storage to supply power in the evening that day. • Community is much better off than before for currently they pay for charging mobile phones at nearby establishments and kerosene used for lighting purposes. Total cost incurred in past: ~INR 200 per month. With the implementation of a solar micro grid, the expense is likely to be only INR 60-70 per month • Sun Edison will provide O&M for a period of five years. Any complaint will be addressed within 72 hours and any faulty parts replaced Solar Home Systems • Cairn has also provided 500 Solar Home Systems (SHS) through which each household is provided solar panels on their own rooftop to generate power. • Model: The project also involves community participation to ensure ownership and sustainability. Approximately 20% of the total project cost will be contributed by the community (each household will contribute INR 7,500 which will be collected by the vendor directly); as in the case of the micro-grid. • The capacity of each system is 200 Wp (minimum of 0.5 units per day of usable power); an run 4 CFLs, 1 fan and 1 TV (for few hours) and mobile charger, this is needed to create satisfaction among community. Vendor will also provide 3 switches, 2 holders for CFLs, a socket where a mobile charger, TV or fan may be plugged and internal wiring

Objective

To provide electricity to those households in Barmer which had no electricity provision till date with a view of improving their quality of life
