Here we go again. After getting shot down by the Maryland Public Service Commission, Baltimore Gas and Electric is resubmitting a plan for its $800 million smart grid project. BGE is changing how it plans to finance the effort by lifting some of the burden of paying for the upgrade from customers’ shoulders. At stake is $200 million in federal financing — one of the most generous outlays — so the pressure is on. In another example of the tightrope utilities have to walk while deploying smart meters, Oncor is learning to get its ducks in a row before foisting the devices on customers. Tip: If customers have solar panels, make sure all the links in the net metering chain are in place. Otherwise, suffer their media-savvy wrath.
