Battery plant delivers:

• frequency control

• voltage control

• short-circuit power

• Instantenous switchfrom acting as generation to acting as load (or vice versa) based on the state of the island grid

Battery storage delivers all grid balancing services traditionally supplied by the synchronous machine

We don’t build island energy systems based on computer simulations, we test them before!

To address the technical issues in island projects, Younicos has set up the Island Test Site in 2009 to simulate up to 100% renewable energy based grids using wind, irradiation and load measurements from any specific location.

Battery plants can provide frequency regulation more effectively and efficiently than thermal power plants

“Price” of providing frequency regulation with conventional plant (study by KEMA):

· Reduced plant efficiency

· Increased fuel costs and emissions

· Higher maintenance costs

· Reduced plant life

· More incidents of technical failure

Thermal plants react slowly:

100% power for frequency response within 30 seconds

Batteries react quickly:

100% power for frequency response within milliseconds

Faster, more accurate and CO2 free frequency regulation!

Attractive business cases for lithium-ion battery plants delivering primary frequency response

Large-scale pilot:

• 10 MW/10 MWh lithium-ion battery plant delivering primary frequency response

· Younicos is the project developer and builds the turn-key battery plant

· Cooperation with a renowned cell manufacturer (20 yr. performance guarantee)

· Commissioning in Q1 2013

Short-term pilot:

• 1 MW sodium-sulphur battery delivering primary frequency response

· Commissioning in Q2 2012
