Market Coupling and the Need for Clarity: Navigating Risks and Maximizing Liquidity

Market coupling, a mechanism aimed at reducing market fragmentation and promoting uniform price discovery, has garnered attention for its potential to increase economic surplus. However, amidst its promising prospects, there are areas of ambiguity and potential risks that need to be thoroughly examined and addressed before proceeding. In this article, we will explore the comments and suggestions on market coupling, emphasizing the importance of clarity and the need for independent operation until all aspects are fully understood. Additionally, we will delve into the significance of deepening and broadening short-term transactions on power exchanges to enhance liquidity.

Market coupling, in theory, holds the potential to create a more integrated and efficient power market. By aligning the power exchanges and facilitating cross-border trade, it can lead to a more streamlined market structure. However, the staff paper highlights concerns regarding irreversible and disruptive structural changes that may arise from coupling the power exchanges. These changes demand careful consideration and extensive discussions to minimize potential risks.

To ensure a comprehensive understanding of market coupling, it is crucial to address the areas of ambiguity and potential risks before implementing any changes. Without clarity on these aspects, it would be unwise to introduce market coupling, as it could have unintended consequences. Therefore, until all concerns are thoroughly examined and resolved, it is advisable to allow the three exchanges to operate independently.

Simultaneously, while awaiting clarity on market coupling, it is essential to focus on deepening and broadening short-term transactions on power exchanges. By increasing liquidity, power markets can become more efficient and responsive to demand fluctuations. To achieve this, we propose three actionable advice:

• 1. Enhance market communication: Improved communication between market participants, regulators, and stakeholders can foster transparency and facilitate the sharing of best practices. This can lead to a more informed decision-making process and a better understanding of market dynamics.

• 2. Promote market incentives: Introducing incentives for market participants to engage in short-term transactions can encourage greater liquidity. These incentives can take the form of reduced transaction fees, rewards for active participation, or incentives for providing liquidity during peak demand periods.

• 3. Explore technological advancements: Embracing technological advancements can revolutionize power markets and enhance liquidity. By leveraging digital platforms and smart grid technologies, power exchanges can facilitate faster and more efficient trading, enabling a greater number of transactions and improved liquidity.

In conclusion, market coupling presents an opportunity for increased economic surplus and uniform price discovery. However, it is vital to address the areas of ambiguity and potential risks before proceeding. Until clarity is achieved, allowing the power exchanges to operate independently is a prudent approach. Simultaneously, focusing on deepening and broadening short-term transactions can enhance liquidity and improve market efficiency. By enhancing market communication, promoting incentives, and embracing technological advancements, power markets can unlock their full potential and better serve the needs of market participants.
