Can you talk about market developments in the smart grid projects?

Smart Grid applications are booming worldwide requiring new technology evolutions to enable reliable large scale adoptions. We are also running pilot projects to showcase our Technology leadership in smart meters. We are also engaging system integrators to discuss product requirements of smart meters and to facilitate brainstorming opportunities, challenges and scope for highlighting ST’s long technical experience in Power line communication technology for Smart Metering. By leveraging on our  unique System on Chip architecture STCOMET provides the needed technology breakthrough for today and future Smart Grid systems.

ST has new collaboration with meter manufacturer Velankani in India. Tell us more about this.   

The technology collaboration brings together ST’s leading-edge components, including the STCOMET smart-meter System-on-Chip, and the Company’s expertise in smart-meter design and deployment with Velankani’s industrial manufacturing talents and vision to lead India toward an advanced metering infrastructure. The STCOMET-based G3-PLC™ smart meters integrate all key smart-meter functions in a single chip to address multiple smart-grid market requirements. The meters connect Consumers and their Utility supplier to provide real-time metering and data analysis.
