You won't find any tourist tchotchkes if you're shopping at Italy's electricity market. The Gestore del Mercato Elettrico (Manager of the Electricity Market, literally) was set up by the Gestore della Rete di Trasmissione Nazionale (Manager of the National Transmission Network) to oversee operations of the electricity market, also known as the Italian Power Exchange (IPEX). The bulk of the buying and selling takes place in the Day-Ahead Market; fine tuning is done in the Intra-Day Market. In the Ancillary Services Market, Terna has a hand in controlling the power grid system operations. The Gestore del Mercato Elettrico (GME), operational since 2004, is owned by the Italian Ministry of Finance and the Economy.
