Solar Power Plant

Today, anyone can set-up a solar power plant with a capacity of 1KW to 1MW on your land or rooftop spaces. The Govt. of India (MNRE) latest guidelines state that “Now anyone can generate electricity through solar power system and surplus electricity can be export through net-metering system. The installation of net-metering at the site will connect it to grid via state electricity board or distribution companies. Ministry of new and renewable energy (MNRE) and state nodal agencies are also providing 20%-40%  subsidy on solar panel for residential consumers.These regulations were long awaited. This will boost solar or green power generation across the state and encourage people to install solar power system on their rooftops.

On Grid Solar Power Plant

On grid solar system is grid (Government electricity supply) connected system. In the first priority this system will run your home appliances or connect load (without any limit). If your connected load will exceed the capacity of installed solar power plant it will automatically use the power from main grid. And if your connected load is less, it will supply surplus power to the grid. This type of system is recommended to reduce electricity bills only.

Government’s special scheme for farmers for the installation of solar pumps and grid-connected solar power plants 

India is an agriculture-based country. The agricultural sector provides a livelihood to over 50% of India’s population. In fact, the sector contributes 18% to the country’s GDP. However, the agricultural sector needs proper irrigation facilities and other amenities to reap proper benefits. The major constraint in this sector is farmers’ dependency on pumps for irrigation. Most of the farmers use pumps some of which are connected to the grid while some pumps run on diesel and other fossil fuels.

According to a study conducted by KPMG.this sector consumes almost 20% of the installed power in India. 

Another issue in this sector is related to the plight of farmers. Since some of the crops are seasonal, most of the farmers are deprived of regular source of income. Furthermore, farmers are not being able to earn anything from their dry/uncultivated land. Solar energy can be put to good use to address these critical issues of the agriculture sector.  Solar energy is one of the most vital renewable sources of energy that can be utilized for various purposes. 

Solar energy is widely being adopted in residential, commercial and industrial sectors and it has huge potential to benefit the agriculture sector. So, with an endeavour to offer financial and water security to farmers, the Indian government has launched various schemes to promote the installation of grid-connected solar power plants and solar pumps. 

The scheme is divided into three different components – installation of standalone solar pumps, solarisation of grid-connected pumps and commissioning of grid-connected solar power plants. Through this scheme, the government targets to add 25,750 MW of combined solar capacities (all three components) by the year 2022.  

Components of the new scheme 
The scheme has a total of three main components: 

  • Component A – 10,000 MW of Decentralized Ground-Mounted Grid-Connected Renewable Power Plants of 500 kW to 2 MW individual plant size to be commissioned by 2022. 
  • Component B – 17.50 lakh standalone solar powered pumps with capacity up to 7.5 HP to replace diesel-powered agricultural pumps. 
  • Component C – 10 lakh grid-connected agricultural pumps with up to 7.5 HP individual pump capacity to be solarised by 2022. 
  • The government intends to execute components A and C of the scheme in a pilot mode till 31st December 2019 whereby commissioning of 1000 MW capacity of ground-mounted solar power plants and solarisation of 1 lakh grid-connected pumps would be completed. In the case of component B, the entire scheme would take place full-fledgedly.  
  • Component A and its implementation: 
    1000 MW of decentralized ground mounted grid-connected renewable power plant 

    • Individual farmers, panchayats, cooperatives, Farmer Producer Organisations (FPO) can install solar power plants of capacity ranging from 500 kW to 2 MW. In specific cases, distribution companies (Discoms) may allow installation of plants with less than 500 kW capacity. 
    • It is preferred to install the solar plant within 5 km radius of substations to keep the losses and well as the cost of sub-transmission lines low. 
    • Discoms will declare sub-station wise generation capacity which can be fed to the grid by solar plants through a particular sub-station.
    • Discoms would purchase the power generated by solar plants. 
    • The State Electricity Regulatory Commission (SERC) of each state determines the feed-in-tariff (FiT) at which Discoms can purchase power. A PPA (power purchase agreement) for 25 years will also be signed by them. 
    • If the aggregate capacity generated is more than that notified by the Discom, then a bidding route will be followed as directed by MNRE. Here, the ceiling tariff for bidding will be the FiT.
    • The project can be installed on any land. In the case of agricultural lands, stilt fashion should be adopted to set up the power plants and sufficient space between panel rows must be ensured. In this way, farming can also be carried out in the land. 
    • The Indian government will offer Procurement Based Incentive (PBI) at the rate of 40 paise per kWh or Rs 6.60 lakhs per MW per year (whichever is lower) to Discoms. The PBI will be given for five years from the plant’s Commercial Operation Date. 
    • If the applicant is not being able to gather enough equity for the installation of the project, then they can approach the local Discom or a developer. In such a case, they can receive lease rent for their land. The rent will be set after the mutual agreement of both parties. A model lease agreement will be created by MNRE. 
    • If developers are involved, then the lease rent would be set as Rs/unit energy generated/unit land area or Rs/year/unit land area. 
    • The lease rent will be directly credited to the bank account of farmers/landowners.
    • The State Nodal Agencies (SNAs) in coordination with Discoms, State/ UTs and farmers will implement the scheme. 
    • Farmers will receive assistance from SNAs throughout the project be it in case of project development, DPR creation, PPA/EPC contracts, getting bank loans or issues related to the selection of power plants. 
    • The Discoms would act as facilitators for the beneficiaries and help them in the successful implementation of the scheme. ‘Must-run’ status of the plants and ‘ON’ state of feeders during the daytime would be ensured by them. 
    • Benefits 
        • It will offer a stable source of income to landowners for at least 25 years. 
        • In this way, farmers can even earn from their uncultivable land. 
        • A minimum installation height will ensure that farming activities can take place along with solar plants in case of cultivable lands. 
        • Through the scheme, sufficient solar power can be generated to power agriculture pumps and to fulfil other power requirements of the area. 
        • Transmission losses can be reduced as the decentralized power plants would be installed near substations and agricultural loads. 
        • Discoms can achieve RPO target through the scheme.

Component B and its implementation: 
17.50 lakh standalone solar pumps to be installed 

  • In the case of agricultural lands where there is no source of power, the individual farmers will get support to replace diesel-powered pumps with a standalone solar pump of up to 7.5 HP capacity. 
  • The central government will provide Central Financial Assistance (CFA) of 30% of the benchmark cost or 30% of the tender cost (lower one of the two). 
  • The central government will provide Central Financial Assistance (CFA) of 30% of the benchmark cost or 30% of the tender cost (lower one of the two). 
  • The state government will also provide financial support (30% of benchmark cost). So, the farmers would be required to pay only 40% of the cost of the standalone solar pump. However, the farmer can avail bank finance of up to 30% of the cost. In this way, initially, only 10% cost will be borne by the farmer.
  • In case of states like Jammu & Kashmir, Sikkim, Himachal Pradesh, Uttarakhand, Lakshadweep, Andaman & Nicobar Islands and northeastern states, CFA is 50% of the benchmark cost or tender cost (lower one of them). Financial support equivalent to 30% of the cost is offered by the state government. Out of the remaining 20%, farmers can avail a bank loan for 10% of the cost. In this way, initially, they only have to pay 10% of the installation cost. 
  • This scheme is only applicable for replacing diesel pumps with solar pumps in dark zones/black zones (areas where groundwater level is below critical level). It is not applicable for new standalone solar pumps.
  • In order to save water, micro-irrigation techniques would be encouraged. 
  • In case the area is facilitated with a grid in the future, the surplus power generated by standalone pumps can be fed to the grids and farmers can make some extra income out of it.
  • 2% of the CFA will be given as service charges to the implementing agency — Discoms, Irrigation Department, Agricultural Department or any other department — as designated by the state government. 
  • Implementing agencies must set up remote monitoring systems in order to monitor the system’s performance after installation. 
  • SECI, EESL or other similar agencies would be responsible for the centralised procurement of pumps/panels/controllers.
  • Benefits 
    • Solar pumps can save a huge amount of cost that is spent on buying diesel. 
    • They provide a reliable source of irrigation to farmers. 
    • Solar pumps can also help in curbing pollution that is caused by burning diesel.

Component C and its implementation: 
Solarisation of 10 lakh grid-connected agricultural pumps 

  • Support will be given to farmers under this scheme to solarise their grid-connected agricultural pumps. Two times the pump capacity in kW is the permissible generation capacity of the solar PV system to be installed. The generation capacity can be lower, as per the decision of the state government, but it cannot be less than pump capacity in HP.
  • Through solarised pumps, farmers can meet their irrigation needs and sell the excess power generated to Discoms.
  • A CFA of 30% of the benchmark cost/tender cost (lower one of them) is offered to farmers. 
  • 30% of financial support is given by the state government. 
  • Out of the remaining 40% cost, the farmer can avail a loan from the bank for 30% of the cost. So, initially, the farmer has to pay only 10% of the cost.
  • In case of states like Jammu & Kashmir, Sikkim, Himachal Pradesh, Uttarakhand, Lakshadweep, Andaman and Nicobar Islands and northeastern states, CFA is 50% of the benchmark cost or tender cost (lower one of them). 30% of the cost is offered as financial support by the state government. Out of the remaining 20%, a bank loan of 10% can be availed by farmers. So, initially, they’ll have to pay only 10% of the installation cost. 
  • The upper limit of the CFA would be the cost of the solar PV system with a generating capacity which is twice the pump capacity in kW or 15 kW (lower one of the two). The CFA would be limited to the CFA that can be availed for a 7.5 HP pump even if the capacity of the pump is higher than 7.5 HP
  • 2% of the CFA will be given as service charges to the implementing agency (Discoms, GENCO or any other department as designated by the state government).
  • Only existing grid-connected pumps would be solarised in dark/black zones. 
  • Discoms should ensure ‘must-run’ status of the plants and the feeders should also be in ‘ON’ state during the daytime.
  • Benefits 
    • The farmers will receive a reliable source of power for irrigation. 
    • Farmers can feed surplus power to the grid and save both water and electricity.
    • Farmers can get a secondary source of income by selling electricity to Discoms 
    • Discoms can meet their RPO targets.

Off Grid Solar Power Plant

Off grid is a battery based solar power system, In the first priority this system will run your home appliances or connect load (as per solar inverter capacity). And surplus power feed in to the solar battery bank, provided with the solar power system. This type of solar power are recommended where power cut are the major problem.

Hybrid Solar Power Plant

Hybrid is a combination of on grid solar system as well as off grid solar system. One side hybrid solar system connects with the main electricity grid and simultaneously it will also provide battery backup to you.

Business Models:

Solar Plant Investment Model

There are two ways to get solar power system installed at your home, business, institute or industry.
 In India principally there are two major business models: 
• CAPEX – capital expenditures are provided by the rooftop owner; 
• OPEX – capital expenditures are covered by third party. 


CAPEX Model (One Time Investment)

In CAPEX model (capital expenditure will be yours) you will have to pay the complete system’s cost to system installation company in one shot and this would be your own system. And you will be get benefited for free electricity for next 25 plus years. If you are planing to install solar system for home or small business and your instillation size is less than 100 kW, then the best way to get it installed is CAPEX model.

Rooftop-solar-power-plantsweb-768x243 HOME


In OPEX model (operation expenditure will be yours) system installation company will install the complete system at their own cost on your rooftop through a 15-25 year Power Purchase Agreement (PPA) between you and installation company. After that you just need to pay per unit on monthly basis. The PPA rates (Rs. 5.50 to Rs.10) are depend on your installation size, PPA time period and your company’s credit rating. If you want to install solar system for your institute, business or industry and your installation size is above 100kW. You can go for OPEX model.
OPEX or PPA model :
You might not want to build your own solar system but rather then this, you want to buy the electricity produced by the solar system. That way, you don’t have the upfront costs, construction and maintenance to worry about. Maybe someone else will be happy to build a solar plant on your roof (or nearby) and sell you the power through a Power Purchase Agreement (PPA). This model works typically for industrial and commercial solar system consumers and Indian companies have started offering it to residential customers in some cities. A PPA is a formal agreement between an electricity consumer (in this case, you) and the electricity generator (usually an investor) that specifies terms and conditions of electricity purchase. Details usually include the length of the PPA (typically 15- 25 years) or  the price (tariff) for the power from the solar plant and annual escalations (if any). OPEX model is also called the power purchase agreement.
