Status
• Today– Gamified Consumer Portal in alpha test – 400 households in Canton Ticino (CH), AMI at 1 hr resolution
• End of 2015– Deployment in Valencia with Emivasa, Grupo Aguas de Valencia.– 650'000 smart meter in 2015 (490'000 already deployed)– Access to 2500+ smart meter at 1h resolution
• 2016– Deployment in London with Thames Water
• Long term investment: 3 M smart meter before 2030 (40’000 in 2015)
