- AGORA(TM) Optimizes Real Time Supervision and Control of Electrical
Transmission and Distribution Networks

- AGORA(TM) is Key to Avoid Major Black-Outs in California

BARCELONA, May 27 /PRNewswire/ --

The Spanish group, Aplicaciones en Informática Avanzada (AIA), announced
today that the U.S. Patent and Trademark Office has granted them a patent on
AGORA(TM) (Advanced Grid Observation Reliable Algorithms), its system to
operate electric transmission networks.

"AGORA(TM) is working on the electric power grid of California through 
our US subsidiary, EleQuant, Inc. The granting of this patent marks a 
milestone for AIA by acknowledging that our model optimizes control and 
minimizes losses in electric power grids", stated Regina Llopis, Chairman and 
CEO, AIA.

AGORA(TM) offers proven solutions to the challenges faced by electric
utilities operating high voltage grids and companies distributing mid and low
voltage. Electrical grid networks have become more complex with the growth of
renewable energy sources, intelligent meters and control elements like Facts
(Flexible Alternating Current Transmission System), which require new
intelligent tools to optimize operations.

AGORA(TM) represents a new generation solution for network operations,
increasing the reliability of the transmission networks and dramatically
decreasing the risk of congestion, instability, or voltage collapse. It also
provides real-time support to blackout restoration.

AGORA(TM) is based on an innovative LFA (Load Flow Algorithm) which is
deterministic, non-iterative, non-ambiguous and capable of solving complex
multi-node calculations, even in situations near voltage collapse. This
algorithm has important advantages relative to the traditional Newton-Raphson
method, and provides reliable and exact information.

About AIA

AIA specializes in solving complex problems in the energy, financial
services, healthcare, and telecommunications sectors. In Europe, AIA has
developed innovative solutions for intelligent electric grid observation and
operation, forecasting electric power demand and optimizing hydro-electric
power.

AIA began operations in the US in 2002 establishing its subsidiary,
EleQuant Inc. in San Francisco. Following the US patent, EleQuant will bring
to market its products for utilities, as well as for independent ISO
operators, regional transmission operators, and other companies involved in
the operation and distribution of electricity in the US and Canada.
