ENERGYINLisbon, November 17, 2015

Identify average consumption patterns in hotels by

energy services

International and national benchmark in terms of

energy consumption

Identify opportunities for renewable energy

Biomass (Space heating, Hot Water)

Solar termal (Pool heating)

PV (all services)

TOPICS

WHAT IS ENERGYIN

IMPROVE THE COMPETITIVENESS OF THE COMPANIES IN THE

ENERGY SECTOR THROUGH THE DEVELOPMENT OF

TECHNOLOGIES AND INNOVATION

o Participation in sectorial studies in energy

Biomass is already

competitive with gas

• Gas (26%)

• Biomass (3%)

Solar thermal is not

competitive

Many electricity

based systems

HOT WATER - CURRENT

Biomass is competitive with other technologies

PV – SELF CONSUMPTION

Source: Csilva2015

Self consumption regulation since 2015

• No Feed-In tariffs

• No net-metering

• Excess can be sold to the market

0,9×Price of the Market

PV – SELF CONSUMPTION POTENTIAL

Source: Csilva2015

SELF CONSUMPTION IS COMPETITIVE WITH THE GRID

• Average installed power = average power

• South-East orientation might be optimal

Many opportunities

Biomass for space and hot water

PV for self-consumption

Traditional solar thermal systems are

deployed

• Opportunities for new solutions
