It will in no event be used to limit or restrict TI or TI's customers. The high solar market penetration scenarios also present challenges associated with scaling up this resource. When insolation is low, many more solar generating devices must be installed to meet a given level of demand, and the network needs to be ready to handle all the electricity flowing from those devices on the occasional sunny day. This jointly sponsored forum was held to address the CPUC's California Solar Initiative goals as well as the DOE SunShot's strategic goal to make solar energy cost-competitive with other forms of electricity by the end of the decade. Therefore, these models are important for understanding possible future pathways for renewable electricity penetration. The 20 percent wind power scenario would cause significant land-use and atmospheric emissions impacts.
2 Challenges of solar deployment at high penetration
The most common distributed generation resources expected to be connected to the distribution system are photovoltaic PV systems, which include customer-owned and utility-owned solar installations ranging from single PV modules 0. Almost 3, GW p of capacity would be built, covering 30, square miles in the southwestern United States. Assuming that the average-sized wind turbine would be in the 1—3 MW range, with modest introduction of large 4- to 6-MW turbines, there could be a total of almost , wind turbines installed Wiley, ; DOE, Perhaps surprisingly, many of these advanced features are already installed in inverters around the country, but they are disabled by default.

Accommodating all of the solar generation as shown in Figure 2 requires nuclear generators to vary output which is not current practice in the U. Several additional challenges for the economic deployment of solar PV also occur as penetration increases. Rapid changes in photovoltaic PV output as the sun comes and goes will require running expensive power plants that can respond quickly to changes in demand. On a more macroscopic level, McClurg and others note, smart inverters can help the grid balance the fluctuating quantity and quality of power that comes with increased intermittent resources like solar and wind.

Already, the initiative has attracted praise from some utilities dealing with growing rooftop generation.
Generator constraints would likely prevent the use of all PV generation in Figure 2. Different generation mixes in the years and are tested with a unit commitment model. Net metering can have the effect of reducing, canceling, or even turning the variable component into a negative value. The scenario estimates that wind power would replace coal- and gas-fired electricity generation and reduce CO 2 emissions to million tons per year in Realizing the scenarios would entail substantial economic activity, including the addition of thousands of new manufacturing and construction jobs in the wind industry, and would provide significant carbon reductions. The 10 percent solar study by Pernick and Wilder examined conditions that would allow combined PV and CSP electricity generation to reach TWh by , approximately 10 percent of the estimated 4, TWh of total electricity generation Pernick and Wilder,
