Case study showing project and performance data and energy-efficiency measures for a DOE 2019 Housing Innovation Award winning home that was certified to the DOE Zero Energy Ready Home criteria.
This case study describes how the Tower Companies selected and successfully executed onsite solar photovoltaic installations at its commercial office properties and highlights the resulting increase in asset value.
This case study was presented at the ICTP-IAEA VIRTUAL Course on Nuclear-Renewable Integrated Energy Systems: Phenomenology, Research and Development. It provides preliminary results on an analysis of hybridizing the two nuclear power plants owned by Xcel Energy and located in Minnesota. The analysis extends previous analyses that provided only price-taker results. Those assume adjusting the generation sold to the grid does not impact locational marginal electricity prices nor do they estimate impacts on the total net cost to serve the load. This presentation summarizes the new technique that was developed to both optimize the size and operations of the hybridized system and the resulting impacts on the grid when it is operated optimally.
This case study describes how Healthcare Realty partnered with a renewable energy advisor to establish its solar program and make progress towards its energy and GHG emissions reduction goals; all of the projects in the pipeline will be financed through third-party ownership, via power purchase agreements or through a feed-in-tariff program.
