Positive start for Greek, Italian, Slovenian intraday coupling

The coupling of the Greek, Italian and Slovenian intraday markets took a positive first step yesterday with a successful trial. According to Greek energy exchange sources, the transition from local intraday auctions (LIDAs) to regional intraday auctions (CRIDAs) covering the three countries was successfully completed.

Two complementary CRIDAs have been staged without any problems, while a third session is scheduled to take place early today.

The first CRIDA session ended with electricity price levels at 149.64 per MWh, 14.31 percent below the LIDA auction level recorded a day earlier. The initial CRIDA session’s transactions represented a total electricity amount of 2.53 GWh.

As a result of the market coupling, intraday market transactions will no longer be limited to domestic restrictions but will also utilize the capacity of the Greek-Italian grid interconnection left over once electricity import and export activity, through day-ahead markets, has been completed by the two neighboring countries.

Utilization of the grid interconnection’s leftover capacity will offer greater flexibility to suppliers, producers and self-supplying consumers.

The coupling of the Greek, Italian and Slovenian intraday markets represents a first step towards European intraday market unification.

It is planned to be followed, on March 8, by Greece’s entry into the European Cross-Border Intraday Market (XBID), offering continual intraday market transactions, via Italy and Bulgaria.

Greek-Italian-Slovenian intraday market coupling in autumn

Market coupling of the Greek, Italian and Slovenian intraday markets has been scheduled for September 21 through complementary regional intraday auctions (CRIDAs), a further step towards full unification of the European electricity market.

This market coupling move promises to bolster the liquidity of Greece’s intraday market, which has remained subdued since its launch several months ago, while also easing balancing market burdens of participants.

A liquidity boost in the intraday market is necessary for optimal management of intermittent production, as is the case with most RES units.

Greece’s coupling with Italy and Slovenia constitutes the first step in this direction, the intention being to avoid significant discrepancies for RES units and costs they cause.

The degree to which this coupling step will impact Greece’s intraday market remains to be seen, given the limited capacity of an existing subsea cable linking Greece and Italy, offering 500 MW.

This interconnection will require a capacity boost if high-level intraday market activity is to be achieved, as the infrastructure will need to be able to facilitate physical deliveries of electricity amounts ordered.

Also, the interconnection’s leftover capacity for intraday market trading will depend on the level of electricity import and export agreements established through the preceding day-ahead market.

For example, if, on certain days, the interconnection’s capacity is entirely taken up for day-ahead transactions, then intraday market trading will not be possible.

A second step in the coupling of Greece’s intraday market is planned with the country’s entry into the continual XBID (Cross Border Intraday) market with Italy and Bulgaria, planned for the first quarter of 2022.

PPC list of electricity import traders for 2019 contains surprises

The main power utility PPC’s list of traders chosen for electricity imports in 2019 from grid interconnections north of Greece contains certain surprises.

A number of major players have not made PPC’s recently approved list of traders for 2019, while firms limited to minor transboundary electricity trade roles last year –  through Greece’s grid interconnections with Bulgaria, Fyrom (Former Yugoslav Republic of Macedonia) and Albania – have been included.

PPC’s list of traders for 2019 is comprised of Alpiq, CEZ, EFT, Elpetra, Enmar, Freepoint, Grand Energy, HSE, Green, LET and Terna Energy Trading.

Four of these, Elpetra, Enmar, Freepoint and Grand Energy, were not involved in any trading activity with PPC last year.

According to a related monthly industry report, electricity imports last December were provided by six traders, these being Alpiq (33.302 MWh), CEZ (19 MWh), EFT Slovenia (21.295 MWh), HSE (28.375 MWh), GreenEnv (33.116 MWh) and LE Trading (1.417 MWh).

PPC and Alpiq operate a subsdiary firm in Bulgaria focused on transboundary electricity trade.
