Conversely solar PV for irrigation systems on load control rates and without net metering have poorer economic returns. For more than 60 years, Valley ® center pivot irrigation equipment has earned its reputation as the most trusted brand in the industry. Pryor points out that the energy cost alone in this example for each inch of The number of acres covered by each 1,295-foot pivot also varies between Cases 1 and 2. Total costs for the wheelline and center pivot systems were estimated to be $191.73 and $176.81 per irrigated acre, respectively. To compare operating costs across the three cases, we assume 5-acre … It is clear from these scenarios that irrigation costs can vary significantly from field to field. The model simulations show that solar PV arrays with interconnection agreements which include net metering have shorter paybacks than interconnection agreements without net metering. Conversely solar arrays on center pivots which can utilize a load control rate have longer payback periods and lower net present value. Using SAM allows for detailed analysis using hourly load data and hourly solar PV production estimates. Center pivot is the most expensive method of row crop irrigation. On an annual basis (spreading costs over the useful life of the equipment), Case 2 has the lowest cost per acre of $139.26. Because the number of acres and water sources differ between Cases 1 and 2, a smaller 25 HP pump is required in Case 1, compared with a 50 HP pump in Case 2. Additionally, Nebraska’s net metering law calculates excess generation at the end of each month, so during months with no electric load all solar PV generation is net excess generation and is compensated at the avoided cost rate. The decision whether or not to invest in solar is an individual decision. Case 1 uses a 50 HP variable frequency drive while Case 2 uses a 50 HP soft start pump panel. Electricity or fuel charges will normally cost $4-5 per inch of water applied. All of the additional costs from irrigation must be covered by the increase in yield from irrigating. An estimated 55,000 center pivot systems are being used in Nebraska to irrigate about 6.7 million acres… Consequently, the cost of 3 acre-feet of water for lettuce growing in a city is nearly $5,000. Additional data needed for these calculations are the number of adjacent acres to be irrigated and the estimated acre … The cost per acre for a pivot varies directly with its length. The time required for a rotation depends on the system size, pump, or well capacity and the amount of water to be applied at each application. May 1, 2009 Q1. Learn how pivot irrigation can be a smarter and more cost-effective way to irrigate a variety of key crops around … 160 Acre Center Pivot Example Estimating Annual Irrigation Operation Costs Standard 160 acre system and end gun with actual irrigated area of 132 acres installed at a cost of $48,000 with a power and water source and connecting equipment cost of $30,000. It is a self-propelled system that rotates around a central pivot point. The center pivot makes a full circle with a pivot length of 1,142 feet, so it covers 111 acres. Most systems in use today have electric drive systems. A field’s distance from the electric grid can also significantly affect the initial costs of irrigation. We towed it to four different pivot points for several years. Net present value is by far the best financial metric to determine if an investment is worth pursuing. How do you set a “fair” price for irrigation, given the following scenario? With no-till farming and a savings of 3 to 5 acre-inches of irrigation water, the annual operating cost savings range from $20.10 per acre to $33.50 per acre. The conclusion here is not whether to invest or not, but rather which center pivot scenarios are better suited for better return on investment and which pivots a farmer may want to target first if considering solar installations. In Case 1, the center pivot rotates a half circle covering 64 acres, while in Case 2, the center pivot rotates the full circle so it covers 134 acres of cropland. For more than 60 years, Valley ® center pivot irrigation equipment has earned its reputation as the most trusted brand in the industry. Pryor points out that the energy cost alone in this example for each inch of water applied is $4.62 per acre. Conversely, without net metering all excess generation is valued at the avoided cost rate. In return for this limitation farmers receive a reduction in the cost of electricity. This was especially visible on some of his hilly, sandy acres … Linears travel back and forth across your field, instead of around a central point as a center pivot does. Lettuce needs about 3 feet of water with conventional irrigation (sprinkler, flood or furrow). Fipps recommends center pivot or linear move for large acreage with sprinkler irrigation. This calculates out to a direct irrigation … On a quarter-mile (1320-foot-long) pivot that irrigates 126 acres, the installed cost may average The depth of water applied in a given application is determined by the speed at whi… Even though total investment costs were largest in Case 2, investment costs per acre in Case 1 were the largest due to the smaller number of acres covered by this pivot. Costs of drilling a well typically range from $30,000 to $60,000 based on the depth of drilling and the ease of which a suitable ground water source is found. A new center pivot irrigation system needs a water source (well or surface water), a pump, a power source (electric motor or engine), controls and often a buried pipeline. Since the product of the system is electricity, there is greater benefit when electricity prices are higher. At 2018 prices, the average cost of a new quarter section It is important to get field-specific cost estimates from equipment dealers, electric companies, or well drilling companies during the planning process to ensure that your decision to irrigate will be economically sustainable in the long run. Behind the meter solar PV have the best chance of economic return for center pivots on farms without load control and with net metering. The cost to install center pivot is high — approximately $325 per acre for F. John Hay 402-472-0408 Jhay2@unl.edu https://bioenergy.unl.edu, 105 Ag.

So how do you know if your irrigation investment will pay off in the long run? 40 acre Center Pivot System Example. When beginning the planning process, talk with your electric supplier to get an estimate of the initial and operating costs associated with a given field. acre, the most costly system was linear move. Solar PV generates electricity during the daylight hours peaking in early afternoon. For questions or comments please contact F. John Hay. The center pivot makes a full circle with a pivot length of 1,142 feet, so it covers 111 acres… Decisions on whether to invest in irrigation equipment are tough to make, but irrigation can mitigate one of the largest risks in crop production. Rather these provide calculated estimates used for comparison of payback values and net present value compared to load control and net metering. To study the economic feasibility of solar connected irrigation systems, scenarios were created and modeled using the National Renewable Energy Labs System Advisor Model (SAM). The System Advisor Model is a free modeling tool which can be used for solar PV system design as well as economic analysis. Center pivot irrigation system. In Case 3, surface water is pumped from a pond to the irrigation site. In Case 2, groundwater is pumped directly to the center pivot from a well. A soft start pump panel reduces the torque during startup to limit stress on the system and minimize pressure surges. Zimmatic Center Drive with AT Gearbox. The difference is predominately caused by electric rate schedules (electricity cost) and net metering policy. If a field does not have access to electricity, the farther it is from the grid, the more expensive it will be for the electric company to provide a line extension. The farmer in Case 1 would need a much higher increase in yield worth roughly $207 per acre to consider investing in that irrigation system. Check your state's policy at.

Electricity used on site usually has higher value than electricity sent to the grid. DIYers need to factor in the cost … will reduce pumping cost per acre results in an increased water application rate for a center pivot. Lamm notes that on similar smaller fields, the cost of a center pivot per acre may be about the same cost of SDI. Communications Bldg.Lincoln, NE 68583-0918. The center pivot cost includes an estimate of income foregone on 30 corner acres … The drive mechanism for this system may be water pressure, hydraulic oil, or Some electric companies may charge extra fees to turn on electricity each month to a specific field or for running a high-powered electric pump. Field size have decreased and equipment prices have more than doubled in two decades. Two factors causing some of the largest variation in irrigation investment costs are access to surface water and electricity. Irrigation - Center Pivot acre $22.43 1.00 $22.43 Power unit acre $9.88 1.00 $9.88 acre $24.50 1.00 $24.50 $56.82 _____ ____ Well, pump, and gearhead Interest on durable equipment Irrigation - Center Pivot acre $28.04 1 The center pivot makes a full circle with a pivot length of 1,142 feet, so it covers 111 acres. The economic impact of system size was observed in the modeling results of and not detailed in this article. The model also allows for individualized economic inputs such as tax rate, insurance, loan amount, loan rate, depreciation, incentives, and discount rate. Yet the net present value is determined using a discount rate to discount future cash flows. Our oldest pivot was new in 1983 and it was a three tower towable Valley. Hourly load data was created (mock data) to represent each of these scenarios. Estimating Annual Irrigation Operation Costs 3-10. ... Total Head (m) (pivot only) $1.20 per litre diesel $1.50 per litre diesel $2 per litre diesel; 21.0 m(30 psi) 25.20… Case 3 had the smallest per-acre investment costs, though operating costs per acre were nearly twice as much as in Cases 1 and 2. See how pivot irrigation can increase yields. The model simulations show that solar PV arrays attached to center pivot irrigation systems with non load control rate schedules have the fastest payback and highest net present value. In addition to calculating your total irrigation costs, it can calculate the cost of using a pivot to irrigate a parcel on adjoining land. Behind the meter systems can be sized to produce up to 100% of annual load, yet generally systems sized to produce 50% to 75% have better economics than larger systems. Initial cost of Anthony’s drip system was about $1,400/acre. This is because with net metering, some of the solar kilowatt hours flowing to the grid (excess generation) are valued at the retail rate of electricity. Solar electric generation, often called photovoltaic (PV) and center pivot irrigation appear to be good partners. If the center pivot is used for the full 20 years, the annual fixed cost per acre would be $129.21. Proper installation and regular monitoring will ensure long lasting system performance needed to maintain energy production.
