First, as we're replacing aging assets on the distribution side, we're looking especially at how we modernize the grid, so we're putting in equipment at the same time to facilitate that. It's a cost-effective way of introducing this new technology into our distribution system.
As well, we have a grid modernization program going on right now, and we're starting off with a few projects. Our AMI meters, the commercial and industrial meters, are starting to roll out. We have an enhanced distribution management system that we're implementing so that as the numbers of customers with renewables come online, we're able to operate the system effectively and have good visibility and control of everything.
Those are the first two stages of the system we're working on. We're probably spending in the order of about $100 million on the distribution side just for sustaining assets and preparing for grid modernization.
