Minus 3% Project

SHINING EXAMPLE
prepared within the project
“Shining Examples for the Implementation of the Energy End-use Efficiency and Energy Services
Directive”
TITLE
OF ACTION: SUBSTITUTION OF THE GASOIL BOILER
BY BIOMASS BOILER AT “LAS ANEJAS” PUBLIC SCHOOL
(ESCO PROJECT FOR SME)
PLACE OF IMPLEMENTATION: Teruel City, Spain
The city of Teruel is the capital of the province of the same name and together
with Zaragoza and Huesca, they make up the Autonomous Community of Aragon,
located in the Northeast of Spain.
Located at an average elevation of 915 m above sea level, it has mountainous
topography
and
a
continental
mountain
climate. Its summers are
warm and dry with
significant
thermal
variations and very cold
winters; it is characterized
by scant rainfall (373
mm/year) and frequent,
strong,
dry,
cold
Northwest
wind
(the
Cierzo).
The cold winters and thermal oscillations added to strong and cold winds increase
the consumption needs by heating, especially from October to May.

AIM OF THE ACTION:
 10 % energy saving.
 Reduction > 147 Tn CO2 emissions / year.
 12,000 € / year saving (electricity invoice).
 Modernization of the heating facilities and SHW.
 Applying of new maintenance protocols and for management.
 Increase of citizens’ awareness on environment.
DESCRIPTION OF IMPLEMENTED MEASURES:
Energy services contract oriented to SME and maintenance fully guaranteed (best offer
through public tender).
 Operation of the energy management and maintenance; giving
full guarantee for the heating installation of the “Las Anejas”
public school by Energy Services Company (ESCO) to give
following provisions:
o
Energy management for the right functioning of the facilities
(heating and SHW).
o
Preventive maintenance of the facilities.
o
Repair and replacement of all those devices deteriorated in
the facilities (full guarantee).
o
Improvement works and renewal of the facilities (execution
+ financing):

Substitution of the 697 Kw gas oil boilers by a 800 Kw automatic biomass boiler
(pellet and woodchips).

Improvement of the pipes insulations, installation of an energy counter and
optimisation of use schedules...

KEY ECONOMY DATA
SIZE OF INVESTMENT/ANNUAL COSTS IN EUR:
EXPECTED ANNUAL SAVINGS (EUR/YEAR):
SIMPLE PAY-BACK PERIOD (YEAR):
280,000 € ( depreciation included)
Energy cost reduction: 12,000 €/year.
Annual net profit: 2,100 € (depreciation
included) during a 15 years period
15 years
OTHER BENEFITS:
Outsourcing of the use and exploitation of the facility.
Efficiency improvement and modernisation of the facilities free of charge for the Town Council.
Generation of synergies for improving the energy efficiency and the use of biomass.
Increase of the citizenship’s environmental awareness.
The economic feasibility study carried out has been executed on the basis on the following
fundamental elements: energy costs, maintenance, reparation of components and finally
depreciation of the facilities.
With the current management juncture, the yearly cost amounts to 43,259 €:
- Energy cost:
30,875 € (gasoil)
- Reparations costs: 2,445 €
- Maintenance cost:
645 €
- Depreciation cost: 9,294 € (4)
With the management cost planned through the ESCO, the yearly cost amounts to 41,095 €:
- Energy cost:
18,824 € (pellet)
- Reparations costs: 3,100 €
- Maintenance cost:
645 €
- Depreciation cost: 18,526 € (5)
(2) Total expected savings by 2020 in final energy terms: 30% on 26,738,860 kWh/year = 8,021,658 kWh/year
(3) Neutral cycle of emissions from biomass.
(4) Current cost of the facilities /useful life = 158,006 € / 17 years.
(5) Estimated cost / useful life = 277,890 € / 15 years.

MINUS 3% PROJECT
MINUS 3% is a 3 year project supported by the European Commission, through the Intelligent Energy
for Europe Programme. Its aim is to establish shining examples for the implementation of the Energy
End-use Efficiency & Energy Services Directive (2006/32/EC) in cities.
The participating cities will show that it is possible to save 3% of the City Authority’s own energy
consumption per year. The energy reduction targets are long term to reach minus 30% by 2020, and each
city will have a different year-by-year result to meet this target.
The participating cities are implementing, with assistance of their local Energy agencies, energy saving
measures and will demonstrate to other cities, that systematic energy consumption reduction is possible!
The project also promotes energy services and their market development through the application and
assessment of energy services contracting in the cities own building stock.
