Balance sheet of the first year of O&M at the ENCE biomass plant in Mérida

Having received the Final Commissioning Protocol from the Ministry of Agriculture, Rural Development, Environment and Energy of the Extremadura Regional Government, Ence’s biomass generation plant in Mérida started to deliver energy to the electrical system in April 2014. With the construction and commissioning of the Sener turnkey project for the biomass plant having been completed,
Ence – the engineering and technology group – set up the company Biomasa Mérida O&M S.L. to provide operation and maintenance works for the facility’s first two years of operation. Following signature of the provisional acceptance of the plant by Ence, Biomasa Mérida O&M S.L. accepted its mission and started work on 15 September 2014.

The Mérida plant is a facility that generates power from biomass, with an installed capacity of 20 MWe and an annual production of 160 GWh. It is equipped with a high efficiency thermodynamic cycle incorporating reheating and regeneration designed by SENER to meet Ence’s specifications.

The facility consists of a biomass processing and treatment area (PTB in its Spanish acronym) plus a boiler area and a power island. The PTB consists of a storage area for stocking 15,000 tonnes of rolls of biomass (logs), with one month of operational autonomy; a crusher that can process 100 tonnes/hour; a system for screening and separating denser pieces; and a biomass chip storage silo to guarantee an uninterrupted supply to the boiler; in addition to all of the conveyor belts that connect to the system.
