The budget for the execution of the Okina phase amounts to a total of € 320,000.00. (VAT included) and for this purpose, the Basque Government’s Rural Development and Environmental Development program financed € 259,921.04. Taking into account that these grants arrive once the project has been executed and paid, the owner of the work has to previously disburse the total amount thereof.

2011-2015 KNOWING

The budget for the entire bioenergy part, including the distribution network is € 582,128.00. And the same as in Okina, there is funding from the Basque Government of € 456,359.43. It should be remembered that these grants arrive once the project has been executed and paid, so the owner of the work has to previously disburse the total amount thereof.

For disposal of to the wood generated from the cleaning of the forests of the municipality, it was decided to build a biomass plant that would provide heating and hot water to the 20 buildings of the town.

Sabando

Supply of sanitary hot water and heating through micro heat networks in the municipality, to take advantage of the biomass existing in the surroundings of the municipality, optimizing the performance of these common systems with respect to the individual ones, generating local work and cleaning the mountain, with what this implies in fire prevention.

OKINA

EXECUTION : PHASE I 2010

Given the pressure on the start of the works, it is decided to execute the project in two phases. The first phase consists of introducing the district-heating necessary for the conduction of hot water to the buildings, taking advantage of the opening of trenches planned for the renovation of the basic services described. This is already done with the necessary tests for possible leaks before paving.

EXECUTION: PHASE II 2013

And this second phase, consisted of:

1. The construction of boiler room.

2. Acquisition and assembly of heat production boilers together with the accumulator elements, safety and control valves and the agitation system. These boilers will be fed with woodchips that will come from the annual management of the forest, which is mostly beech forest.

3. Acquisition and assembly of exchangers, measuring elements and connections with individual installations.

Heat production: 2,500 kWh / month for public buildings and 30 single-family homes. Wood chips obtained from forest resources in the area for the biomass boiler.

In Okina remote heating is provided to all inhabitants in an environmentally friendly way through a 500 m pipe network.

It stands out for being the first town in which a distribution network is installed that reaches all its buildings, both public and private.

SABANDO

EXECUTION: 2013

In 2013 the installation and burial of networks was undertaken and the appropriate tests were carried out before paving.

Heat production of 3,500 kWh / month fed through a network of 1,500 meter pipes to individuals.
