Tierra is the lead consulting group in the development of Tucson Electric Power’s 2019 Demand Side Management (DSM) Portfolio. We are working with TEP staff to generate a portfolio of measures that not only benefits customers, but also alleviates peak demand on stressed feeders and shifts load into times of excess supply on the grid. By analyzing a heat map of electricity incremental cost within TEP’s service territory, and the load shapes for new and existing measures, we are able to evaluate the percentage of savings for each measure that occur in desirable, neutral, or undesirable hours. With this analysis, we can develop a strategic portfolio that adds value to the grid, and can prevent costly infrastructure investments on over-burdened feeders and distribution circuits. Our final deliverable for this project will be a comprehensive portfolio of DSM measures that is within TEP’s budget, and addresses low-income, special interest, schools, and other important program sectors.
