Microgrid – just another definition

Source: Microgrd Market, Global Forecast & Analysis (2012-2022), adapted

Microgrid

A Microgrid is electricity generation and loads, and in some cases

storage managed collectively in a network. Besides electricity,

microgrids may include other vectors such as heat, gas, water.

Microgrids manage energy resources according to a given set of

criteria. They may be operated in off-grid-, on-grid as well as in dual

mode to optimize technical (e.g. power quality, frequency) and

economic aspects (e.g. optimal use of renewable energy).

In an optional emergency mode the microgrid provides blackstart

capabilities.

CoC Islands

Islands …facing significant challenges

Dependence on oil:

The current electricity mix of most

small islands is dominated by

diesel or heavy fuel oil Missing interconnections

Power demand:

Islands expect an average

increase of 24% from 2009 to 2020

Emissions:

To comply with the IED, small isolated energy system

operators need to reevaluate the energy chain of value

Security of supply and system stability

How to address these challenges?

Solution: Storage Enabled Islanded µgrids

But the requirements for energy providers are not the same everywhere...

Moving towards low-carbon generation led by RES

Average generation cost for solar energy with storage,

calculated at USD 0.27/kWh (Source: Tractebel, 2012).

Diesel based Islands w/ cost up to 1 USD/kWh
