NEC partners with Acea to provide Energy Storage Systems for Smart Grid project in Rome

NEC will provide a real-time monitoring system for the temperature and charge-discharge status of ESS, which assures system safety and reliability.

Rome & London, February 11, 2013 - NEC Italia S.p.A., a wholly owned subsidiary of NEC Europe Ltd., and Acea Spa (ACE.MI), the Italian multi-utility serving the Rome metropolitan area, announced an agreement to develop innovative lithium-ion Energy Storage Systems (ESS) to be implemented in Acea's primary and secondary power substations.


The agreement, signed in December 2012, marks the beginning of a major partnership framework between NEC and Acea for enhancing the Smart Grid development in Rome.

NEC will deliver two ESS (180kW/100kWh and 100kW/50 kWh) which represent the key elements of Acea's Smart Grid project designed to improve the quality of utility services, reduce energy losses and improve the management of distributed energy generators, such as photovoltaic systems and wind power systems. The ESS will start operation in September 2013, and contribute to several applications that include peak shaving/time shifting of power consumption, power balancing, power-system stabilization and power outage backup.

The 180kW/100kWh ESS connected to Acea's low-voltage electricity grid will serve as an emergency backup power source in the event of a utility grid outage. The 100kW/50 kWh ESS, coupled with Acea's photovoltaic power plant and connected to its mid-voltage electricity grid, improve service quality and continuity of distributed energy generators by compensating for power fluctuations. In addition, NEC will provide a real-time monitoring system for the temperature and charge-discharge status of ESS, which assures system safety and reliability.

"NEC is proud to partner with a visionary company like Acea, who understands the importance of Smart Grids for successfully meeting the demands of utility companies as well as reducing environmental burdens," said†Ugo†Govigli, Vice President, Smart Grid Solutions, NEC Europe. "These ESS were designed entirely by the NEC EMEA Energy competence center which was established in Italy in 2011. We expect these developments to pave the way into new energy market segments throughout EMEA."

"This is an exciting step forward for Smart Grid design, especially in consideration of the complex energy distribution network of the Rome metropolitan area," said Marco Staderini, CEO, Acea SpA. "Our company is fully committed to maintaining and improving the superior quality of its electric power services. For this reason, we are working with highly qualified partners like NEC, who is able to meet our requirements for the Smart Grid project from both energy and ICT perspectives."

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
