GridStat is a new kind of publish-subscribe data delivery service designed specifically, from the bottom up, for delivering real-time operational data of the electric power grid. We overview the data delivery needs of the electric power grid and analyze why neither the Internet and its existing technologies nor existing publish-subscribe products and research meet these needs. We introduce periodically updated variable and periodic update flow abstractions and describe how GridStat, as periodic update flow middleware implements these abstractions with very low latency and high availability.
