task six we talk about renewable and task 7 hydroelectronic. what we need to do are the recommended next steps to go out and refine what the overall cost are. leveraging the prior studies and determining how large the various projects would be and get up dated bids for what they would cost. part of what's happened in the last few years, the cost of solar has gone down. it's not actually the cost driver for those types of projects, it becomes more of the labor and aluminum framing that becomes the cost driver. so the task themselves are commodity. so getting estimates for what the various projects would cost and determining whether the construction and supply of generation can be supported by the competitive rates that are envisioned. that's along with that second bullet point where there are a variety of estimates for how much this will cost for the build-out plan and the required estimates is required. with the addition of hetch hetchy system there is the opportunity to add more efficiency to projects. that seems to be some of the most cost-ef
