Electricity Demand Management; As clearly stated in the reports published by the Electricity Market Supervision and Regulatory Board (EPDK) and the Ministry of Energy, Turkey's transmission and distribution network is getting older and lagging behind the requirements of the age.
Figure-1 has shown an increase in demand by year. Considering the electricity demand increase estimated at 6.7% each year and 7.5% with high scenario, our transmission and distribution network will be under increasing amounts of electrical and thermal stress in the near future.
Imported energy dependency is 71.5% in turkey's electricity market, europe's 6th largest economy and electricity market. High external dependence on meeting energy demand; Epdk's energy investment needs for the period 2010-2030 has played an important role in predicting the need for investment as $225-280B.
In addition, the importance of evaluating domestic and renewable resources, the need for resource diversification; With the goal of increasing our gross electricity consumption per person (3099 kWh/year) to similar levels at about a third of the EU average, the economy has great potential for high energy density, increased energy efficiency and new energy investments.
Proximity to resources from our geopolitical position and our potential to become an energy terminal have forced us to take supply-demand security in the energy field more seriously.
Southeast Anatolia and Eastern Anatolia regions, especially; Technical loss and leakage rates of up to 70% on transmission distribution lines have sent distribution companies to take precautions and improve network infrastructure.
With the increase of unlicensed production to 1 MW and the cheapning of technology; Renewable power plant installations, especially wind and solar plants, are increasing day by day.
Such plants do not show a specific structural sequence, but are generally built away from central consumption points.
Energy losses (I2R) occur due to the resistance of the conductor in transmission and distribution lines. Energy quality is as important as losses in electricity transfers. Technologically sensitive devices need quality, safe and sustainable energy.
Electricity Demand Management – ENTSO-E
Turkey has not yet been fully integrated into the European transmission and distribution system (ENTSO-E) due to voltage fluctuations, frequency changes and power outages caused by overloading in the current energy transmission system.
In to solve these problems, energy quality was monitored by established a national energy management center and energy analyzers were established on the primary side of certain power transmission lines.
Turkey's transmission system is monitored in real time by the National Power Quality Monitoring Center and the negativity in the system is tried to be removed with the necessary interventions.
Thus, the necessary energy quality standard is tried to be provided in order to comply with entso-e system. The connection phase to ENTSO-E was planned to take place in 3 stages and the first 2 stages were successfully performed.
Phase 3 of the trial operating period is planned to be completed by autumn 2013. Currently, trade with Bulgaria and Greece is limited to the monthly tender procedure.
When all stages are completed, trading is planned on a daily daily period. European Union countries that implement nuclear power de-power policies continue to invest more in renewable energy sources.
Therefore, it wants to transfer its energy potential in Turkey to the union continent via ENTSO-E connection. In addition, with projects such as Desertec, which is expected to be carried out in the long term, Turkey is expected to be a strategic bridge for energy resources in North Africa and the Middle East and consumption in Europe.
Turkey continues to work on disseminating the real-time monitoring system on transmission lines. However, real-time monitoring systems are not yet widely installed on distribution networks. The data collected from the monitored points can not yet be evaluated with detailed analyses.
Electricity distribution privatisations are nearing completion and the loss-and-leak rate is an average of 18%. Figure-5 illustrations of region-by-region distribution companies after privatisations.
According to TEİAs 2010 data, the annual transmission loss rate in Turkey was 2.8%, while the transmission loss rate 1.9% edificased according to 2011 data after the SCADA/EMS National Energy Monitoring System was established.
