Due to the characteristics of the operation of a hospital, their demand for supplies and the need for uninterruptibility, hospital
becomes an energy-intensive building. Currently, energy policies of building operation are based on strategies of energy saving
and efficiency. In order to carry them out, it is necessary to get information about the consumption profile of the target building
and make decisions based on it. The aim of this work is to analyse the different options for contracting an electricity supply for
large consumers, such as hospitals, in an attempt to achieve the greatest savings in energy costs. The possibilities of managing the
purchase of energy from these large consumers were discussed and analysed. It was concluded that there is a wide range of
contracting possibilities beyond the traditional ones (fixed or indexed contract). It also highlighted the need for qualified personnel
to assume the responsibility of studying the different modalities of purchase since it will provide an enormous benefit to hospital
management.

del mismo, el hospital se convierte en un edificio energéticamente intensivo. En la actualidad, las políticas energéticas de
explotación de edificio se basan en estrategias de ahorro y eficiencia energética. Para poder llevarlas a cabo, es necesario
disponer de la información acerca del perfil de consumo del edificio objetivo y tomar decisiones en base a ello. El objetivo de este
trabajo es analizar las diferentes opciones de contratación del suministro eléctrico para grandes consumidores, como hospitales,
presenten el mayor ahorro de costes energéticos. Se discutieron y analizaron las posibilidades de gestión de la compra de energía
a estos grandes consumidores. Se destacó como principal conclusión el amplio abanico de posibilidades de contratación más allá
de los tradicionales (contrato fijo o indexado). Asimismo, se destacó la necesidad de disponer de personal capacitado para asumir
la responsabilidad de estudiar las diferentes modalidades de compra puesto que aportará un enorme beneficio a la gestión
hospitalaria.

Spanish hospitals amounted to 419 ktoe, representing 6.71%
of the total consumed by the service sector [3].

he current technological level associated with the daily
activity of a hospital demands an enormous amount of
electrical energy to meet medical and comfort needs.
Hospitals are very energy-intensive buildings operating
uninterruptedly 24 hours a day, 365 days a year [1].
Quantifying the costs incurred during the life cycle of a
building, it is summarized that: 5% correspond to the project
phase, 20% to the construction phase, 65% to maintenance
and operation and the remaining 10% to rehabilitation or
demolition [4]. Hospitals are energy-intensive during
operation, so they will have a higher percentage of costs
during this phase.
In addition, they have a continuous need for availability of
supplies, medical equipment, special requirements for air
conditioning and air quality and disease control, which makes
their energy intensity superior to other buildings in the tertiary
Although it is expected that in the near future this demand will
