The special characteristics of the Aegean islands region

A. People

� Not urban municipal profile (not the common case of CoM).

� Small towns and settlements with a few people.

� Strong connection of the citizens with their land. Common case the “not in my backyard” syndrome. The consent and collaboration of the locals is crucial.

� Developing life standards result to an increasing trend of the energy consumption. (Greece is considered by the Kyoto protocol as less developed EU country allowing a 25% increase to GHG emissions until 2012).

� Domestic immigration flow from the urban areas of the mainland towards the islands (increasing energy consumption).

� Touristic destinations leading to high population fluctuationbecause of seasonal residents (most of the cases at least triplicatedduring summer months).


Kostas Komninos 7


B. Energy – Environment (1)

� In most of the cases the islands are autonomous or a part of an

autonomous electrical system supplied from conventional

electricity units (diesel) located on the island or a nearby bigger island.

� Future plans and scenarios for interconnection of some of the

electrical autonomous islands to the mainland electrical system

would change the energy profile of the island.

� Plenty of free area in comparison with urban municipalities (in many

cases municipal area) providing potential for RES applications.

However, land-planning restrictions can result to site constraints.

� Close distance to the sea offering potential for several applications

(high wind potential, desalination, district cooling...).


Kostas Komninos 8


B. Energy – Environment (2)

� Shortage of water in many cases, leading to imports of water with

vessels.

� The autonomous character of the islands makes it essential to

provide all the primary sector facilities (energy consuming) within

the borders of the island:

� Solid waste treatment (recycling, …)

� Water waste treatment (biological waste water cleaning units, …)

� Drills to exploit the underground water or desalination units

Most of the municipalities are still under development of these units.

� Areas of particular natural beauty (Natura, natural parks, rare flora

and fauna …).


Kostas Komninos 9


C. Administrative

� Small municipalities with limited abilities of widespread actions in relation to the Covenant. However, it is easier and more direct to take decisions and act.

� In most of the cases not existing employees with specialized skills to deal with the Covenant.

� In most of the cases not-existing or lately developed database with energy consumption records.

� Logistics constraints (roads, ports, …)

� Higher investment cost


Kostas Komninos 10

Methodology for the SEAPs: The baseline emission inventory template (1)

A. Final Energy Consumption

B. CO2 or CO2 equivalent emissions


Kostas Komninos 11

Methodology for the SEAPs:The baseline emission inventory template (2)

C. Local electricity production and corresponding CO2 emissions

D. Local heat/cold production (district heating/cooling, CHPs…) and corresponding

CO2 emissions


Kostas Komninos 12

Methodology for the SEAPs:Assumptions and main choices (1)

� Overall CO2 reduction target:

� Per capita

� Absolute

The high yearlong fluctuation in population makes the per capita calculation unreliable. An absolute target for its case is set.

� Baseline Year:

� 1990 is proposed by CoMO→ rather difficult to gather reliable data

� …or the closest year to 1990 with the most reliable data

Considering:

� The last years increasing trend in energy consumption

� The difficulty to retrieve past years data from the local authorities

The last year with complete energy data is chosen → 2008


Kostas Komninos 13


� Approach to emission accounting and reporting:

� Standard emission factor in line with the IPCC principles

� LCA (Life Cycle Assessment) factors

For matters of simplicity the IPCC approach is chosen

� Energy consumption increase rate:

� Increasing life standards

� Developing infrastructures

� Domestic immigration flow towards the islands

The conservative approach of disregarding the increase rate is followed

� Industry sector:

The industry sector is not included at this point in any of the cases.

� Agriculture sector:

The agriculture sector is not considered by the Covenant and at this level

this approach is followed. It should be reconsidered in the future.


Kostas Komninos 14


� Fuel consumption data (heat & transport):

� Data from the local gas stations are collected. Possibly underestimated fuel consumption for the transport sector since visitors arrive with full tanks and leave with empty.

At this level we assume the gas station data sufficient

� If gas station data are not available the transportation energy consumption share is estimated using existing information from other similar islands. The fuel consumption for heat production is then estimated from the bottom-up analysis.

� Future interconnections to the mainland electrical network:

The future possible interconnections are not considered at this level.

� More than one municipality on the same island:

Only the applications and SEAPs located in the geographical area of the signing municipality are considered.

Methodology for the SEAPs:The emission inventory approach

Final Energy Consumption

Existing data provided

by the local authorities

Results from the

bottom-up analysis

1.Used technologies

2.Energy efficiency coefficients

3.Type of fuels consumed

Statistical data

Demographics – Transportation

Tourism – Local climate

1.Municipal electricity and fuel

consumptions

2. Total fuel consumptions

CO2 emissions× Emission Factors


Kostas Komninos 16

Methodology for the SEAPs:The emission factors

� The emission factors provided by CoM are chosen

� Emission factor for electricity consumption when local production exists (EFE)EFE = [(TCE - LPE) * NEEFE + CO2LPE] / ( TCE )

where

TCE = Total electricity consumption in the local authority [MWh]

LPE = Local electricity production [MWh]

NEEFE = national emission factor for electricity [t/MWh]

CO2LPE = CO2 emissions due to the local production of electricity [t]


Kostas Komninos 17

Methodology for the SEAPs:Initial SEAP approach

� Initial qualitative definition of SEAPs are pointed out for each case based on:

� RES potential of the respective island

� Transportation significance in final energy consumption

� Existing or planned actions

� State of electrical network

� Site constraints

� Water resources availability

� Topographical characteristics

� Municipal and residential buildings condition

� Municipal lighting weight in energy consumption

� Former experience of the local authorities

� Interest of citizens and investors


Kostas Komninos 18

Methodology for the SEAPs:Initial SEAP approach

� Although the priority of the Covenant lays upon the reduction of the

final energy consumption, for the Aegean islands the high RES

potential makes it apparent that actions related to the supply side will dominate the SEAPs.

� SEAP priority areas:

1. RES in energy supply

2. Small RES integrated in the settlement areas

3. Energy savings in public buildings, equipments/facilities

4. Promote energy savings in residential and tertiary sector

5. Land planning, define land uses

6. Transportation


Kostas Komninos 19

The case of Ios

Special characteristics

� Major touristic destination

� Interconnected to the Paronaxia

autonomous electrical network

Ios in numbers

� Population: 1862 (2001)

� Wind turbines installed capacity: 1.2MW (2008)

� Annual electrical energy demand: 14.87GWh (2008)

� Annual wind energy production: 3.57GWh (2008)

� Peak electrical demand: 4.48MW (2008)


Kostas Komninos 20

The case of Ios

Total energy

consumption:

31.7GWH

Energy Consumption

balance:

Categ.A = 51%

Categ.B = 49%

Total CO2 emissions:

14655t

CO2 emission balance:

Categ.A = 72.6%

Categ.B = 37.4%


Kostas Komninos 21

The case of Ios

Potential Sustainable Energy Actions

� Hybrid electricity production with wind turbines and pumped storage for maximization of wind energy penetration

� Energy savings in public buildings and lighting

� Promotion of energy savings in residential buildings and tertiary sector (hotels, taverns, …)

� PVs installation

� Optimization of public transportation to avoid additional emissions from tourists renting scooters

� Electric bikes/scooters, golf cars charged with electricity produced from small RES applications


Kostas Komninos 22

Concluding Remarks

� An initial methodology and tool is available to define the baseline emission inventory.

� The exact depiction of the baseline emission inventory is in dispute.

� Further data are needed to be retrieved by the local authorities.

� The tertiary and residential sectors need to be approached in a more realistic way (questionnaires, …).

� The sustainable energy actions are expected to address to the energy supply with small – medium or even large scale RES applications.

� An accurate way to estimate the fuel consumption in the transportation sector is needed.


Kostas Komninos 23

Questions (1)

� What do we expect from the small Aegean island local authorities? Their role should be defined.

� How do we deal with the energy consumption increase rate?

� Which part of the wind energy produced on an interconnected island is considered local electricity production?

� A big RES application on an interconnected island is fully considered a SEAP even if it is >20MW providing that there are also other SEAPsdirected to the supply side?

� Should the future interconnections be accounted to the SEAPs? The energy carrier of the same electricity supply will change.

� Do we include the agriculture sector? SEAPs related to this sector are available:

� heating of greenhouses with geothermal energy

� saving water (and energy) by using the produced water from the waste water biological cleaning units


Kostas Komninos 24

Questions (2)

� How do we approach the industry sector? Their energy consumption is not easily estimated.

� How do we quantify the achievement of a SEAP?

� How can we account the energy saving in buildings?

� How do we deal with islands with more than one municipality (Andros, Lemnos, Santorini, Syros)? Synergy is essential?

� Emissions from boats and planes (ports and airports exist within the borders of the municipalities)?

� Can the future desalination energy consumptions be balanced with the current fuel consumption of the water vessels?

� Offshore wind parks are considered SEAPs for the Covenant (Moudroscase)
