In the process of BSP membership participation there are also several other large European utilities that see Southeastern Europe as a great opportunity. BSP SouthPool management believes that the growth of new members will have positive impact on increasing the liquidity of regional energy exchange.

First results of improved liquidity were already seen in February 2009.  This refers to bigger number of bids and concluded transactions.  The total volume of orders on the Slovenian day-ahead market in February compared to the previous month increased for 70% due to enlarged activities of the members of the exchange.

By the summer, management of BSP SouthPool expects to have 25 members. So far, the exchange has 15 members:  Danske commodities, Electrabel, Edison Trading, EGL, Elektro Maribor, Elektro primorska, Elektro prodaja, Enel Trading, Energy financing team, Gen-I, Holding Slovenske elektrarne, Petrol energetika, Rudnap Group, Termoelektrarna toplarna Ljubljana and Verbund.
