Further to this, APX continued its role as a frontrunner of European power market integration by exploring products and solutions to facilitate the changing dynamics of the market.

Market Developments and New Initiatives

Significant progress was made towards an integrated European electricity market. APX, together with its exchange partners and TSOs, is working on several European projects. The NWE market coupling, the first region to implement the Price Coupling of Regions (PCR) solution, is an initiative of European power exchanges and is expected to be launched on 4 February 2014. The solution is developed by the European power exchanges, and it covers 75% of the European power markets. As a result of the NWE market coupling, all APX home markets of the Netherlands, UK and Belgium will be fully coupled, strengthening the role of the exchange in the region. NWE market coupling will also enable APX to launch new products for its members across the markets.

The CWE Flow-Based market coupling, an extension of the existing CWE ATC market coupling, is expected to go live after summer 2014.

In September 2013, Belpex and FEBEG, the Belgian Federation of Electricity and Gas companies, announced their intention to develop a Reserve Capacity Bulletin Board for the Belgian market. It will be made available for all Belgian market participants active on the reserve capacity market. The bulletin board will offer the market parties opportunities to post their intention to buy or to sell reserve capacity. The launch of the Reserve Capacity Bulletin Board is expected in the first quarter of 2014.
