STMicroelectronics Technology Chosen for Electronic Power Metering in Spain

Smart meters to replace more than 13 million traditional electricity meters in
houses over a period of six years

GENEVA, Oct. 5 /PRNewswire-FirstCall/ -- STMicroelectronics (NYSE: STM), one
of the world's leading semiconductor manufacturers and the number one supplier
worldwide of power-management solutions, has announced that it has been chosen
by Enel, Italy's largest power company, to provide the semiconductor
components for new electronic power meters destined for distribution in Spain.
The power meters are key elements of the new remote management solution to be
installed by Endesa, the largest electricity supplier in Spain.

Traditional electromechanical meters are based on a technology that is over a
hundred years old and is unsuitable for further significant development.
Electronic meters offer many significant advantages for the utilities and
consumers, including lower costs for manufacturing, calibration and
maintenance, greater accuracy and, most important, the ability to provide the
consumer with detailed information based on their own real consumption and the
electricity supplier with punctual service quality data. The benefits to both
parties are concrete: consumers can more accurately monitor and control their
consumption (for example, by using appliances such as washing machines,
dishwashers or electric showers at times when the cost is lowest) and energy
providers can generate and distribute power more efficiently.

Over a period of six years (2010-2015), Endesa will complete the replacement
of more than 13 million traditional electricity meters, installed in its
customers' houses, with the new generation of Enel smart meters. The new
system is the result of the combined expertise of Endesa and Enel, its parent
company, which together form the second-largest group in the European energy
market. Enel has already successfully implemented a similar remote-management
system, also using chips from ST, to serve more than 35 million customers in
Italy.

"Enel, Endesa and ST have made great strides in this important project," said
Carmelo Papa, Executive Vice President and General Manager of ST's Industrial
and Multisegment Sector. "By applying ST's extensive portfolio and know-how,
Endesa will use intelligent power metering to reduce the cost to the consumer
while simultaneously increasing the efficiency of the electricity supply
industry, thereby reducing Spain's carbon footprint."

ST will provide a complete smart-metering solution that includes a
breakthrough power-line communication System-on-Chip (ST758x), which is the
heart of the system, a powerful 32-bit microcontroller (STM32), and an
innovative power-supply device, as well as MOSFET and EEPROM memory devices,
as the basis of the new electronic power meter for Endesa.

Moreover, as announced by Enel, the Power Line Communication protocol
(SITRED), applied in this new generation of remote meter management solutions,
will be open to the market. In this way, the Enel Group will make available to
all stakeholders, the first and unique remote meter-management solution,
reliable and proven on more than 50 million meters worldwide. This is a
fundamental and tangible step towards the standardization process launched by
the European Community towards Smart Grid development.

The upcoming meter roll-out by Endesa places ST first in the line to exploit
this new scenario, thanks to its long-standing relationship to provide Enel
with innovative components.

ST is one of the few semiconductor companies in the world that can supply all
of the devices and the system-level expertise needed to cost-effectively
implement them in smart electricity meters. In addition to the new performing
power-line modem platform, ST's portfolio includes a leading-edge
microcontroller family to control the meter functions and several power
supplies that meets the stringent regulations concerning noise and robustness
plus other suitable devices.
