Summary of Private Sector Participation in Power Grids: Turkey Case Study

Core Content

This document presents a detailed analysis of the evolution of private sector participation (PSP) in the transmission and distribution (T&D) segments of the Turkish electricity market. It outlines the historical development, legal frameworks, implementation models, outcomes, and challenges faced during the transition from a state-controlled system to a more liberalized and competitive market.

Main Viewpoints

• PSP in Turkey began early with the establishment of the electricity sector in the early 20th century.

• Three distinct historical periods can be identified in the development of the Turkish electricity sector and its PSP models:

  1. Pre-1984: A fragmented system with private concessionary companies and later state-controlled entities.
  2. 1984–2001: Initial liberalization efforts with the introduction of the Law No. 3096, leading to the development of various PSP models such as BOT, TOOR, and Auto-production.
  3. Post-2001: The establishment of a competitive electricity market through the Electricity Market Law (EML), which introduced a licensing mechanism for PSP and restructured the sector.

• Legal and institutional changes were pivotal in enabling and regulating PSP. The Constitutional Court played a key role in determining the legality of different models, often forcing the use of concession contracts despite the original intent of the Law No. 3096.

• Transmission system is operated by a single state-owned company, TEIAS, which is independent of supply and trading activities. This model ensures a centralized and coordinated approach to transmission planning and operation.

• Distribution system has seen more private participation, with the TOOR model being the primary mechanism. The privatization of distribution companies has been gradual, with 13 out of 21 regional companies now privatized.

• Regulatory oversight is crucial for ensuring fair competition and preventing self-dealing. The Energy Market Regulatory Authority (EMRA) plays a central role in regulating the sector and setting service quality standards.

• Challenges include regulatory uncertainty, high-risk premiums, and the need for a strong judiciary to enforce legal frameworks. There are also ongoing issues related to asset ownership and public service obligations.

Key Information

• Law No. 3096 (1984): Introduced the concept of private law assignment contracts, aiming to enable PSP through BOT, TOOR, and Auto-production models.
• Constitutional Court rulings: Initially restricted the use of private law contracts, forcing the sector to rely on concession contracts. This changed in 1999 with constitutional amendments allowing private law contracts and international arbitration.
• EML (2001): Established a non-concessionaire regime, allowing licensing for market activities and restructuring the sector into TEIAS, EUAS, and TETAS.
• PSP in distribution: Implemented via the TOOR model, with 21 regional companies operating under distribution licenses, 13 of which have been privatized.
• Private sector investments: In the last five years, the private sector has contributed TL818 million ($455 million) to transmission infrastructure, mainly for connecting 281 new power plants.
• Service quality improvements: Privatized distribution companies have reported better collection rates, service quality, and loss reduction through the use of advanced systems like SCADA and GIS.
• Public sector investment reduction: After privatization, public sector investment in distribution has decreased by over 50%.
• Future considerations: A stable and clear regulatory framework is essential for attracting private investment. Balancing public benefit and private incentives is crucial for long-term success.

Implementation Models

1. Concessionary Regime (Pre-1984)

• Private companies operated under concession contracts.
• Public companies were also shareholders of concessionary firms.
• Limited private participation, with only two regional transmission and one distribution companies.

2. Post-1984 (Law No. 3096)

• Introduced assignment contracts and models such as BOT, TOOR, and Auto-production.
• Constitutional Court later forced the use of concession contracts for most projects.
• TEAS and TEDAS were established in 1994, marking the first step toward unbundling the vertically integrated structure.

3. Post-2001 (EML)

• Licensing mechanism replaced concession contracts.
• TEIAS remains state-owned and responsible for transmission.
• Distribution companies are privatized under the TOOR model, with EMRA as the regulatory authority.
• PSP in transmission is limited, but private direct lines and generation companies' investments on behalf of TEIAS are allowed.

Results and Challenges

• Before EML: Moderate private capital inflow into generation, but limited in T&D due to legal and institutional constraints.
• After EML: A more competitive market structure emerged, but regulatory uncertainty and political interference continued to affect distribution performance.
• Operational performance: Privatized distribution companies have improved collection rates and service quality, while loss and theft reduction is a key target.
• Challenges: Lingering issues such as legal ambiguities, political influence, and regulatory inconsistency remain, though expected to be resolved over time.

Conclusions and Recommendations

• A strong and independent judiciary is essential for the effective implementation of regulatory frameworks.
• Clear and consistent regulations are needed to attract private investment and ensure market stability.
• Ownership of T&D assets should be carefully managed, as they are public services and cannot be fully privatized.
• Unbundling and regulatory oversight are critical for promoting effective competition and non-discriminatory transmission services.
• Cost-based pricing is important for attracting private investment, but protection of low-income consumers must be balanced with market efficiency.

Lessons Learned

• Legal frameworks must be robust and adaptable to support long-term market reforms.
• Political will and institutional capacity are key to successful privatization and regulatory implementation.
• Private participation in T&D should be carefully managed to ensure public service obligations are met.
• Regulatory consistency and transparency are necessary to build investor confidence and ensure fair competition.
