Some figures:

More than 180MW photovoltaic, 100MW thermosolar, 4.000MW wind energy, 28MW biomass and a large number of 400KV, 220KV and 132KV electrical substations.

SISENER INGENIEROS was created in Zaragoza (Spain) as a spin – off of Circe in the year 2000, with the clear intention of providing specialized engineering services for generation, transformation and distribution of electricity, focusing on renewable energy.

SISENER INGENIEROS has offices Zaragoza, Madrid, Santander, Barcelona, Malaga (Spain), Milan (Italy), Lima (Peru), Cuenca (Ecuador), Phoenix (USA). The firm has 52 employees in Spain and it reaches 65 employees adding the international offices.

We are developing works for the huge utilities (REE, ENDESA, IBERDROLA, HIDROCANTABRICO), electrical installers (ISOLUX, SEMI, MAESSA, MAETEL, CYMI, TESSAG, EIFAGGE, ELECNOR, GES,ETS), as well as for manufacturers, technologists and promoters (ABB, AREVA, SIEMENS, VESTAS, RENOVALIA, GAS NATURAL, GEA, MOLINOS DEL EBRO, etc.).
