Ceuta is one of those odd corners of the globe, a political anomaly cast up after centuries of political storm. Approximately 7-sq.mi. (18 sq km) territory on the north coast of Africa just west of Morocco, it lies about 12 mi (20 km) across the Strait of Gibraltar from Spain. Its strategic location has made it a contested bit of real estate all the way back to the Carthaginians. At various times, it has been under Roman, Byzantine, Moorish, Berber and Portuguese control. Since 1580, it has been claimed by Spain, and is now a Spanish "autonomous city."
But Ceuta is no backwater. It is a very modern city with daily, high-speed ferry service to and from Cádiz in Spain. It is a free port, and oil, industry, retail and tourism drive its economy. Its population of some 78,000 gets its electricity from the Spanish electric power provider Endesa Generación.
Endesa generates 33% of Spain's electricity and has 25 plants spread over the Iberian Peninsula, plus five in the Balearic islands in the Mediterranean, nine in the Canary Islands, and two in Ceuta and Melilla, a similar city on the north coast of Africa near the Moroccan border. The power plant in Ceuta has an installed capacity of about 100 MW provided by nine diesel generators and a gas turbine.

Like most electricity providers today, Endesa's objective is to optimize its competitive position by producing electricity at a minimum cost, all while maximizing the availability of its equipment, ensuring the safety of its employees and respecting the natural environment. This is a tall order given that Endesa has electrical generating facilites spread out all over the Iberian peninsula, the southwestern Mediterannean and out in the Atlantic Ocean off the west coast of Africa.
Part of fulfilling this tall order means that keeping track of greenhouse gas emissions for regulatory and sustainability purposes is a big issue for Endesa. This effort is supported by Endress+Hauser's Promass flowmeters installed on its facilities' gensets. But installing flowmeters is only part of the solution. Those meters have to be calibrated, in Ceuta's case, every three years. And here's where things get a bit more complicated.
