Current Status of Energy production in Non-Interconnected Islands
TILOS Project: the Facts
Sustainable energy production through TILOS Project
A global disruption in the power sector

3. Energy Production status
Non-Interconnected Islands
Energy Production status
32 autonomous Electrical Systems (ES)
High demand variability on a daily and monthly basis
High RES potential e.g. wind, solar, etc.
Interconnection is underway for some of them (planned for 2020)
In total, RES penetration:
reaches approx. 18% of the annual energy demand
in 1,100 ktns avoided CO2 emissions for 2016
High RES curtailment due to limitations
Generation mainly via diesel-fueled Local Power Stations (LPS)
High generation cost compared to the mainland

4. The FACTS (1/2) TILOS Project
Project name: Technology Innovation for the LOcal Scale, optimum integration of battery energy storage
Duration: to
Website:
Objectives:
Development and operation of a wind-PV hybrid system including a prototype battery storage unit.
Optimum smart-grid control system shall:
Perform microgrid energy management
Maximize RES penetration with focus to grid stability
Export guaranteed energy to the grid, and
Provide ancillary services to the main grid
Additional features:
Demand-Side Management (with smart-meters)
Wind and PV energy forecasting

5. The FACTS (2/2) TILOS Project
The research phase of the Project includes three separate operational scenarios:
Scenario B:
Single grid scenario whereas RES contribution reaches 75% together with the interconnection and/or the diesel genset
Scenario A:
Stand-alone scenario covering demand by 100% RES
Scenario C:
System operation in parallel to the existing electrical grid

Direct benefits to the local community and local power consumers
Development of eco-tourism

7. A global disruption in the power sector
TILOS Project
A global disruption in the power sector
RES with energy storage could offer:
Load shifting
Wind and PV firming & smoothing
Peak saving
Ancillary services & active frequency regulation
Falling costs of energy storage shall:
incorporate new distributed energy alternatives
enable RES to act more as dispatchable units
increase sustainability in the power sector
Energy regulators must:
Assist the energy transition with RES and storage
Encourage appropriate regulations for energy storage
All the above shall contribute towards healthy economics and sustainable future for the power sector
