Cuddalore, Tamil Nadu

The average monthly per capita expenditure of rural agricultural households is relatively low for the district, suggesting poor purchasing capacity of the farmers here. For average crop revenue per holding, the district appears among the top 25 percentile of districts, implying higher investment capacity of the farmers here. There is a comparatively high level of farm mechanization in the district, implying a positive outlook towards progressive technologies amongst the farmers. The district has a relatively high proportion of small and marginal farmers.

Deployment Approaches

Approaches Feasibility
Individually owned off-grid solar pumps Limited Suitability
Solarisation of feeders Limited Suitability
Solar based water as a service Not Suitable
Promote 1 HP and sub-HP pumps Limited Suitability
Solarisation of individual grid-connected pumps Limited suitability

Individually owned off-grid solar pumps

Limited Suitability

The district has a comparatively high concentration of diesel pump users, high crop revenue per holding, and a relatively high disbursement of institutional credit. However, groundwater availability is below the safe limit. Water conservation and efficient irrigation practices (such as drip irrigation) should be promoted to improve the viability of solar pumps.

Parameter Value Percentile
Number of cultivators reporting use of diesel pumps 36,688 67
Water Availability Index 0.68 54
Crop revenue per holding (INR) 163,536 78
Medium and long term institutional credit disbursed in a year (in INR Crore) 30.5 51

Solarisation of feeders

Limited Suitability

The district has a relatively high penetration of electric pumps, and its DISCOM incurs a high cost for supplying power, but the district has a comparatively low extent of feeder segregation. Solarisation of the feeders will only be possible once the district separates agricultural feeders from the rest.

Parameter Value Percentile
Actual cost of power supply (INR/kWh) 6.69 84
Extent of feeder segregation 0% 0
Proportion of cultivators reporting use of electric pumps 33% 80

Solar based water as a service

Not Suitable

The concentration of small and marginal farmers is rather high in the district, but groundwater availability is below the safe limit. In addition, a relatively low proportion of unirrigated area makes it very difficult to promote solar-based irrigation through the water-as-a-service model here, unless it undercuts the price of water from existing sources, and improves water utilisation through promotion of micro-irrigation.

Parameter Value Percentile
Water Availability Index 0.68 54
Proportion of small and marginal cultivators 93% 71
Unirrigated net sown area as a share of total net sown area 14% 16

Promote 1 HP and sub-HP pumps

Limited Suitability

The district has a relatively high proportion of gross cropped area under horticulture crops and a rather high concentration of marginal farmers. But, groundwater availability in the district is below the safe limit, and disbursement of institutional credit to marginal farmers is comparatively low, making it very difficult to promote 1 HP and sub-HP pumps here. Promotion of such pumps must accompany support for marginal farmers (subsidies and loans), along with promotion of micro-irrigation.

Parameter Value Percentile
Area under horticulture crops as a share of gross cropped area 15% 70
Water Availability Index 0.68 54
Proportion of marginal cultivators 80% 76
Medium and long term institutional credit disbursed in a year (in INR Crore) 30.5 51

Solarisation of individual grid-connected pumps

Limited suitability

The district has a relatively high penetration of electric pumps and power supply to its agriculture consumers is heavily subsidised. But the district has a comparatively low extent of feeder segregation and its groundwater availability is below the safe limits. Solarisation of individual grid-connected pumps will only be possible once the district separates agricultural feeders from the rest. Further the approach should be taken up with extreme caution as it may aggrevate the groundwater depletion.

Water Availability Index 0.68 54
Actual cost of power supply (INR/kWh) 6.69 84
Extent of feeder segregation 0% 0

Leveraging Solar Pumps to Promote Policy Objectives

If you are deploying solar pumps in this district then you can further these policy objectives.

Doubling Farmers’ Income – Capital Investment

Given the high concentration of small and marginal farmers, and their relatively better access to institutional credit, the district is suitable for doubling farmers’ income through capital investment. Solar pumps could be one of the farm technologies to invest in for farmers, especially 1 HP or sub-HP pumps for marginal farmers.

Parameter Value Percentile
Proportion of small and marginal cultivators 93% 71
Medium and long-term institutional credit disbursed in a year to small and marginal cultivators (in INR Crore) 30.5 51

National Mission on Oilseeds and Oil Palm (NMOOP)

The relatively low share of oilseeds and oil palm crops under gross sown area in the district makes it a suitable candidate for promoting NMOOP. Solar pumps could meet irrigation needs for these crops and help farmers diversify their yields beyond cereals.

Parameter Value Percentile
Area under oilseeds as a share of total cropped area 49

Per Drop More Crop

In the district, crops suitable for drip and sprinkler irrigation occupy a relatively high proportion of gross cropped area, making it easy to adopt such high precision irrigation methods. Solar pumps, along with other efficient and precise water application devices, could be deployed under Per Drop More Crop to promote efficient irrigation.

Parameter Value Percentile
Area under crops suitable for drip and sprinkler irrigation as a share of total cropped area 27% 58
