RESPONSIBILITIES AND SANCTIONS OF ELECTRICAL PROJECT AUTHORITY IN ENERGY EFFICIENCY

Where is the Electrical Project Designer in these responsibilities?

As you know, the responsibility of the project owner in our country is to design and prepare the project in accordance with the current legislation and regulations, to finalize the project phase by getting the approval of the project from the authorized institutions and organizations. Although it is directly responsible for determining the compensation system capacities, it cannot be held directly responsible in practice for issues such as calculation errors and productivity losses that occur during operation in the design of these systems. One of the main reasons for this is that the "electrical internal facilities project preparation regulation" does not specify the limits of responsibility and sanction related to this issue. At the same time, demand power calculations, which were first used in 1984 and have survived with some revisions over time, become a binding and basis for project authors. The experience we have gained is that the demand power calculations specified in the standard in the measurements made in most of the projects that have been completed and put into operation differ greatly in practice. We do not think that holding the project authors directly responsible and imposing sanctions on this issue will be the solution. Considering that the biggest losses are in distribution transformers and lines, even distribution companies cannot find a solution by reaching a consensus on this issue, and they are not faced with a direct sanction.

Where is the main productivity problem in Projects and Business?

We can list many factors in this regard. However, when we get to the center of the problem, especially in the projects designed for the public, the project authorship costs are quite low, the time given in the design of the projects is limited, the expectations from the project related to the project construction work are not sufficiently specified by the ADMINISTRATION within the scope of the project construction work, and the projects in which the efficiency is not already taken into consideration have emerged. it causes. In the projects put into operation, in order to get the best efficiency from the systems, there is a shortage of competent personnel who can primarily operate the system, monitor the functioning system, and follow the systems in the breakdown, maintenance and repair phases, and the necessary resources for these costs.

What has been done so far?

In some of the projects has been made so far, especially recently, the specifications require the use of high-efficiency devices. At the same time, the infrastructure and equipment that make it convenient to monitor and even interfere with the systems are included in the systems. Automation systems have started to be used especially in subjects such as heating, cooling and ventilation where energy consumption is high.

However, in the design of many projects, lighting designs are still made without considering the lighting calculations, and transformer, generator, UPS, compensation calculations, cable section selections are made with standard power calculations without examining the load profiles. Specifications require the use of directly imported products in many projects, push domestic manufacturers out of projects and prevent them from making necessary R&D investments. In almost none of the projects that are suitable geographically and architecturally, the use of renewable energy systems is not planned by carrying out the necessary feasibility studies.

What can be done next?

Today, where energy resources are so limited and costly, we think that this issue should be carried out especially with a state policy. We think that a very serious feasibility study, planning, design and benefit/cost studies will contribute to the future of our country by managing this in a medium-term process. If it is necessary to list the items;

» The number of projects currently in operation in our country, regardless of the public and private sectors, is determined as the load profile. First of all, the load profiles in the projects that have been implemented should be monitored, the periodic consumptions and losses of all systems should be recorded. will reveal an accurate calculation method. State-private sector-university cooperation is very important in this regard.

» The use of transformers with high A+ energy class efficiency in transformer selections will prevent transformer losses together with the correct power transformer selection.

» Especially the selection of the main energy supply cables of the building as aluminum NA2XH will benefit from high copper cable costs, this gain will contribute to the inclusion of energy efficiency and automation systems in the projects, and the creation of resources for the operation and maintenance of the systems.

» Generator systems selected with high power have high initial investment costs as well as fuel and maintenance costs in operation. In our country, where there are no long-term interruptions, load shedding automation in the projects and the operation of the heating, cooling and ventilation systems, which are mostly for comfort and consume high power, with mains energy, independent of the generator, will provide gain in the initial investment and operating costs of the generator. Services can be obtained for finding mobile backup power supply solutions for extraordinary situations.

» Encouraging the selection of UPS systems with high efficiency and modular type will prevent UPS losses.

» It is necessary to centrally control and monitor the lighting and air conditioning systems away from human control and initiative, and prevent unnecessary high-capacity operation of the air-conditioning devices (open windows and doors, insulation faults, etc.).

» National standards regarding all systems should be reviewed, their deficiencies and faults should be eliminated, domestic manufacturers should be brought to the level of these standards and the use of domestic manufacturers in projects should be encouraged, and the resources allocated for these projects should be prevented from going abroad.

» During the operation phase, it is necessary to outsource services and allocate resources for this issue in order to monitor the systems from a central point, especially in the public sector, and to make determinations for malfunctions and maintenance.

» Feasibility studies related to the use of renewable energy resources should be evaluated for each project and a feasibility study should be carried out, renewable energy sources should be included in the projects.

Although we think that the correct demand power calculation is the priority, we think that this issue is too important to be left to the initiatives and predictions of the project authors, and that the regulations and calculation methods on which the project authors can rely on this issue should be reintroduced. With these studies to be carried out with the cooperation of the State-Private Sector-University and an energy efficiency process managed as a state policy, the designs of the project authors will gain full meaning, their competence and ability levels will be revealed, and the project authors will be held directly responsible for the wrongly designed projects.
