The use of the new guide clarifies measures necessary for entire facilities, resulting in the reduction of initial investment (for engineering, installation work, etc) and the promotion of appropriate maintenance, JPEA said.

The major evaluation items of the guide are (1) titles for power generation business such as power generation, power transmission and business site as well as procedures including regulations related to the use of business sites (land and rights), (2) check of the appearances of site, ground, retaining wall, etc and the states of foundation, mounting system, drainage, etc (civil engineering and structure) and (3) documents related to electricity and the completion of construction, design of electricity, devices to be installed and the design of power generation systems (power generation facilities).

In regard to the evaluation procedure, when the evaluation of a power generation business is requested for selling/buying the business, for example, the business (facility) ID and location of the solar power plant to be evaluated are checked first.

Then, the primary and secondary evaluations are conducted to select evaluation items in accordance with the purpose of the evaluation and decide the details of the evaluation for each evaluation item. Necessary documents are prepared and checked, and on-site check, research and measurement are conducted when necessary.

After that, a report about the results of the evaluation is made, including an overview, detailed list and detailed explanation. If a part that needs to be repaired is found, negotiations will be held with the customer as early as possible. In this way, the customer who requested the evaluation can understand the state of the power generation business and decide to sell, purchase, maintain/inspect or repair a solar power plant based on the results.

In the aim of spreading the use of the new evaluation guide, JPEA intends to publish it online and plan/have related seminars and training courses.
