TECHNICAL AND ENGINEERING SERVICES
Consultancy, project definition and presentation of justification plans
Earning money from solar power plants is the most important factor in attracting funds into renewable energy. But this motivation becomes more attractive by having a comprehensive plan that examines all the economic parameters of the project. These schemes, known as “technical and economic justification”, are the most important step for the construction of renewable power plants. In these plans, by examining the costs and income during the operation period of the power plant, its profitability is accurately calculated and its results are comparable to other economic projects, such as investment in banks. Solar GostarShahran, using detailed technical and economic plans, has the ability to define the projects according to the customers’ demands and outlines the future of these projects.
Usually, investors’ perspective on the construction of a power plant can be viewed from three perspectives:
1. Construction of the power plant based on existing capital
Typically, the amount of your investment will determine your plant’s capacity. But the point that matters to financiers is knowing when to return their capital. The revenue of each power plant depends on the capacity, the amount of solar radiation, the technology used in the plant’s equipment and its overall casualties. Therefore, in this phase, after the presentation of a different technical project, the revenue and expenses of each project will be calculated, and the return on investment, and the rate of profitability of the power plant will be determined, and finally, the best design will be offered to the customer.
2. Construction of the power plant based on the expected income level
One example is: The revenue of solar power plants increases each year due to inflation and currency fluctuations. At times, customers are looking to cover their fixed costs by investing in a solar power plant. Suppose, for example, that a factory will pay $ 100 million annually to its personnel, and each year it will have to raise salaries based on inflation. The director of the factory will pay the salaries of personnel and will not worry about increasing salaries in the coming years to reduce costs by investing in a power plant with an annual income of 100 million tomans and a 4 year return on investment. After 4th year, all the costs of the construction of the power plant are returned to the investor, but the important point is that from 4 to 20 years the power plant still has income, and the owner of the factory from the same income can pay the salaries of his personnel to pay. In fact, the owner of the plant initially pays 4 years of staff salaries and has no paycheck for 20 years.
3. Construction of the power plant based on available land area
Solar power plants require 1.5 hectares of space per megawatt, as shown in the table below, the required power plant area is required. So, if this space is limited, this parameter will affect the size of the power plant.
Network connectivity studies
One of the triple licenses is known as a network connection license to obtain a power plant license. This permit is essential for studies on the simulation of a power plant connection to the national electricity distribution network, and as a result, it is determined that the grid has the ability to absorb the power generated by the solar power plant, As well as in the event of different scenarios such as low-voltage network, overload, voltage drop, or short-circuit, which events are expected to generate power plants.
The study set out in this section by Solar GostarShahran will include:
1 Broadcast studies
2 short-circuit studies
3 Transient Sustainability Studies
4 Power quality studies
5 Conservation coordination studies
6 Earth system studies
These studies are generally conducted by specialized network studies such as Power Factory and Etap.
