In Spain, electricity distribution represents a quarter of the total electricity cost, and consists of 347 companies classified in two different groups: five larger utilities, which feed from the transmission and have, on average, five million points of supply (P.o.S.); and 342 smaller companies, which feed from lower voltage levels and have, on average, less than 5.000 P.o.S. The unitary remuneration is four times higher in the case of the smaller companies, which are operating at lower voltage levels and with a worse quality of service.

We analyze, for the year 2011, a representative sample of 102 smaller distributors in Spain using DEA methodology. Our analysis introduces the change of perspective from the individual firm to the Regulatory body. The DMtTs are the companies, but the information provided by the DEA models is oriented to reducing remuneration of inefficient units (maintaining quality), with corresponding savings for the overall system. The total reduction would rise close to 60 million Euros per year considering only the smaller companies.
