Last week I attended Distributech 2011 in San Diego. What I came away with was the sense that we are well on the way to sorting out the many operational complexities associated with installing and connecting millions of smart meters across the country. Demand response, time of use billing, outage management and ways of tying in renewables are all well on their way to becoming entrenched as standard operational functions. So what is the next stage in the development of the Smart Grid?
