ENERGY CONTEXT OF THE CANARIAN ARCHIPELAGO
Total population: 2 Millions (+ approx. 250.000 equiv. permanently living tourists
= 12 Million per year!!))
7 islands with different dimensions and features (total area: 7.500 km2 Socioeconomic considerations
)
Significant economic development in the last 15 years, GDP based on tertiary
sector (tourism)
Energy
Total external energy dependence
Constant (significant) increase of energy demand
Electricity generation based on fossil fuels (oil), relatively small power stations)
(5) insular electrical systems, very difficult to interconnect (volcanic origin of the
islands)
Low heating energy demand, decentralized heat production

3
ENERGY CONTEXT OF THE CANARIAN ARCHIPELAGO
Recent entry in force of national legislation concerning insular and
extrapeninsular eletrical systems, and entry of the system operator (Red
Eléctrica de España)
Will to diversify energy sources (combined cycle power plants already installed,
waiting for LNG introduction)
Historical lack of water resources and big experience in the search of artificial
water production systems (desalination market began in the 60’s) - Importance
ofthewater-energybinomial
Important weight of the transport sector
Renewable Energies
Excellent potentials (particularly wind and sun), but still low contribution to the
energy balance
Still lack of information, at all levels, about energy saving technologies, demand
management and RE
Very favourable normative framework for RE deployment (National Royal Decree
436/2004 and future Building Technical Code)
Existence of qualified research groups and technology centres with know-how
in this field

RENEWABLE ENERGIES
Other Renewables
Biomass exploitation possibilities: biogas from waste, WWTP sludge, biodiesel (very
small scale)
Geothermal potential still to explore
Interesting wave potential (2000 equiv. Hours in northern areas, 40-80 MW?)
R&D in sustainable hydrogen production technologies

45
RENEWABLES ENERGIES (& WATER) FOR DEVELOPING
COUNTRIES:
Technology transfer to Africa
ITC cooperation projects in the Northwest African Coast (Morocco, Mauritania,
Senegal, Cape Verde, Tunisia)
Elaboration of a feasibility study for the electrification and water supply
(using renewable energy systems) of 32 villages in the province of
Essaouira (Morocco) (finished 2000)

46
Installation of a MORENA unit (hybrid PV-wind-diesel system) for the
electrification of common areas of the village Ouassen (province of
Essaouira, Morocco) (in operation since 2001)
Active participation in the Energy and Water Seminar organised by
CDER/Resing in Marrakech (April 2002)
Organisation of the 1-week Seminar “Desalination and Renewable
Energies”, held at ITC (July 2003), with attendance of
researchers/scientists/personnel from energy and water bodies coming
from Mauritania, Morocco, Algeria, Egypt, Jordan, Palestinian Territories,
etc.
Total electrification of the village Talate Ourgane (Morocco), including
water pumping and ice production demonstration system (on-going)

47
Elaboration of the wind atlas of Northern Mauritania (2000)
Creation of the Thematic Parc “Canary Islands” on Renewable Energies,
Desalination and Drip Irrigation at the Faculty of Sciences and
Technology of the University of Nouakchott, Mauritania (including
maintenance, training activities; on-going)
Installation 4 RO desalination plants (20-40 m3/d)
at the National Parc Banc d’Arguin (Mauritania)
(sent by the Canary Islands’ Government
through ITC; finished)

48
Supply of the 4 Mauritania RO plants with Renewable Energies (starting)
Participation in EC SMADES and ADU-RES projects (on-going)
Technical assistance to spanish PV company ISOFOTON: feasibility of
supplying 15 small RO sea- and brackish water desalination plants with
PV in Senegal (finished)
Elaboration of a Plan for the Promotion of Energy Efficiency and
Renewable Energies in Morocco (finished)
Brackish water desalination plant powered by a PV system in Ksar
Ghilène (Tunisia) (on-going)

RE-H 2 BINOMIAL
OUTSTANDING PROJECTS
Hydrogen (produced by RE) could represent a promising energy storage
solution for islands
Islands could be excellent showcases for the introduction of the hydrogen
economy

HYDROBUS
OUTSTANDING PROJECTS
INTERREG IIIB Project coordinated by ITC:
Feasibility studies for the instalación of Windhydrogen
systems in Azores and Canary Islands

RES2H2 (EC FP5)
HYDROHYBRID (ITC project)
OUTSTANDING PROJECTS
Design and installation, at ITC Pozo Izquierdo
premises, of a wind-hydrogen integrated system for
the controlled production of electricity and water
Small scale hydrogen production driven by a hybrid wind-PV system
(installation on-going)
