The Ence biomass generation plant in Puertollano, a SENER project, is opened

On Thursday, January 9, the new ENCE low-emission, 50-MW, renewable biomass energy plant was opened in the city of Puertollano (Ciudad Real), developed as a turnkey project by the engineering company SENER Engineering.

The event was led by the President of the Board of Castilla-La Mancha, Emiliano García-Page, and was attended by the Mayor of Puertollano, Isabel Rodríguez García, as well as by the CEO of ENCE, Ignacio Colmenares, and its Honorary CEO, Juan Luis Arregui. Representing SENER were the Group's CEO, Jorge Unda, the General Manager of SENER Engineering, Jorge Sendagorta Cudós, among others.

The speeches remarked how this renewable biomass energy plant provides an example of a just energy transition that contributes very positively to the environment. Also significant is the large number of direct, indirect and induced jobs it has created (nearly 27 jobs per installed MW). It will produce an estimated 325,000 MWh/year, enough to supply the energy needs of more than 60,000 people. It will do so by consuming some 238,000 tons of biomass a year, including olive mill waste, vine shoots, olive leaves, and woody forest and agricultural waste.


The Puertollano facility is the third turnkey or EPC project that SENER for ENCE in Spain, after the successful construction of the biomass plants in Mérida - currently in operation - and in Huelva (in commissioning and start-up stage). In all cases, the contract covers the design, supply, construction and commissioning of the plant, as well as the operation and maintenance during the first two years of operation.

All three power plants apply SENER technology, a highly-efficient, regenerative thermodynamic cycle with reheating capability, which includes a furnace with a reheater and a turbine with two bodies - high and low pressure -, as well as several extractions. Also, the plant is refrigerated using cooling towers. All of this will contribute to bringing the plant's gross output to over 35 %. Due to their innovative design, which combines high efficiency and low emissions, ENCE's three power plants designed by SENER serve as a benchmark among biomass power plants.
