Having evaluated the submitted documents, the authorities in Suna may submit their viewpoint to the privatization office in this regard. Afterwards, the construction license will be issued during a legitimate time period.

1.1.2. Feasibility study: preparing feasibility study for solar power plant implementation

The feasibility study report must incorporate the following issues in separate chapters: Project description

The project, or the power plant to be constructed, must be described in terms of the following specifications from a technical perspective:

  • Location: this includes an exact map of the location, all paths towards the location, the appropriate path for equipment transport, the power network and gas piping paths and the like and a topography of the land surrounding the location

  • Power plant's technical specifications: this contains the equipment's technical specifications and those of selected processes, the equipment installation methods and their internal connection and the like

  • Layout: this factor comprises the site plan of the power plant location representing the equipment installation method in the power plant, an estimate of the total land square and effective square of the power plant, a determination of water/electricity/gas/telephone splitting for the location at construction time An estimate of the amount of electric energy produced annually

This includes evaluating the available data related to the location, evaluating energy resources, estimating the annual electric energy to be produced in the power plant and determining factors effective in equipment selection. Considering these, use of related software and typical and standard methods will help to guarantee the estimates and calculations. Connection to the main power network

In this chapter, the connection to the power plant network and the mutual effects of the power plant and network are examined. Thus, in addition to the connection-to-network project, it is essential to conduct the following evaluations and calculations:

  • Examining the available networks and those of being under construction in vicinity of the location intended for power plant construction ( including power substations & power transmission and distribution lines and top distribution network)

  • Examining how to distribute electric load within power transmission substations and estimating the amount of load during power plant exploitation time

  • Examining suggested options for network connection in technical terms and an economic comparison and prioritization of suggested plans

  • Studying the transient stability of the power plant under study in conditions of maximum load and minimum load and at the time of short circuit on important network lines

  • Studying short circuit in order to calculate the maximum level of short circuit on network substations' bus bars to select the degree of the power of switch on/off.

Considering Tavanir Co. or the district power distribution Co. as the certified authority to confirm the connection-to-network plan and to issue the related license, it is essential that all the studies be conducted under the supervision of , and based on the factors indicated by, the above-mentioned companies. An environmental evaluation of the solar (or wind) power plant location

Here, the effects of power plants on the environment must be taken into account although renewable power plants are usually considered to be environmental-friendly. Economic evaluation

After all the technical specifications the design plan of the power plant has been stated, applicants are expected to calculate their suggested project’s costs through typical, standard methods in engineering economics and to confirm the feasibility of the project in economic terms. Although the power costs purchased by power ministry from renewable power plants have been determined in advance and such cost may not undergo any changes, the projects with no economic justification will be totally inhibited. The economic analysis of the solar power plant construction must incorporate an examination and separation of investment costs, repair and maintenance, working capital, the annual income earned during the power plant’s useful life, the present value, the payback period and rate, etc. Solar (wind) power plant’s implementation schedule

The project implementation schedule is provided at the end of the feasibility study report. This schedule may be cited in other phases, at the time of the issuing of the construction license and at the conclusion of the power purchase agreement, in particular. The starting time of the project will be the time when the power purchase agreement is concluded. The project timing will contain three periods as stated below:

  • Initial period, comprising preliminary activities such as conclusion of the contractor agreements signed for equipment purchase or the project implementation, and determining how to maintain contract financing

  • Power plant construction period, including operational measures up to the power plant initiation

  • Exploitation period, containing all activities after the power plant initiation

The third phase may be started based on the employer decision, according to the study results and after the order given to Panianir manufacturing group. This phase incorporates stages of detail design and the power plant implementation, installation and initiation.

2. Small-scale generators (SSG), CHP & CCHP

Distributed generation (DG) is an approach that employs small-scale technologies to produce electricity close to the end users of power. DGs are small-scale generators which may yield power in a maximum capacity of 25mw. Below are some DG types:

  • Small-scale generators(SSG)

Internal combustion engines (ICE) are the most typical and most economical type of small-scale generators. These generators are of gas-fuel type and with regard to advances in related technology, they offer a high degree of efficiency and longevity. Moreover, they need a smaller place for installation and also a shorter time to be utilized.

  • Combined Heat & Power(CHP) & Combined Cooling, Heat & Power (CCHP)

A strategy now used worldwide by energy-related policy makers as an effective tool in energy management is energy production based on a simultaneous production of cooling, power and heat (or cogeneration).

As a particular type of distributed generation, cogeneration may be defined as a simultaneous production of two or more energy forms (e.g. electricity, heat or cooling) from an initial simple source ( e.g. the chemical energy from different fuels).
