While often the cheapest alternative, these tariffs require micromanagement for optimization. In this research, an automated system capable of supplying electricity for home use at minimal cost called Smart Relays and Controller (SRC) is presented. SRC scrapes prices online, charges a battery system during the cheapest time slots and supplies electricity to the home energy system from the cheapest source, either the battery or the grid, while optimizing battery life. To validate the system, a comparison is made between SRC, a programmable scheduler and PVPC (Spain\u2019s dynamic tariff) using twenty-eight months of hourly historical data. SRC is shown to be superior to both the scheduler and PVPC, with the scheduler performing worse than SRC but better than PVPC (T.T., p &lt; 0.001). SRC achieves a 36.16% discount over PVPC, 13.89% when factoring in battery life. The savings are 44.24% higher with SRC than with a scheduler. Neither inflation nor incentives to reduce costs are considered. While we studied Spain\u2019s tariff, SRC would work in any country offering dynamic electricity tariffs, with benefit margins dependent on their particularities.<\/jats:p>","DOI":"10.3390\/bdcc9040073","type":"journal-article","created":{"date-parts":[[2025,3,21]],"date-time":"2025-03-21T11:06:48Z","timestamp":1742555208000},"page":"73","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Home Electricity Sourcing: An Automated System to Optimize Prices for Dynamic Electricity Tariffs"],"prefix":"10.3390","volume":"9","author":[{"given":"Juan Felipe Garcia","family":"Sierra","sequence":"first","affiliation":[{"name":"Department of Mechanical, Informatics and Aerospace Engineering, Universidad de Le\u00f3n, 24071 Le\u00f3n, Spain"}]},{"given":"Jes\u00fas Fern\u00e1ndez","family":"Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Department of Mechanical, Informatics and Aerospace Engineering, Universidad de Le\u00f3n, 24071 Le\u00f3n, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6522-8896","authenticated-orcid":false,"given":"Diego","family":"Fern\u00e1ndez-L\u00e1zaro","sequence":"additional","affiliation":[{"name":"Department of Cellular Biology, Genetics, Histology and Pharmacology, Faculty of Health Sciences, Universidad de Valladolid, Campus de Soria, 42004 Soria, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8277-0700","authenticated-orcid":false,"given":"\u00c1ngel Manuel","family":"Guerrero-Higueras","sequence":"additional","affiliation":[{"name":"Department of Mechanical, Informatics and Aerospace Engineering, Universidad de Le\u00f3n, 24071 Le\u00f3n, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3389-0786","authenticated-orcid":false,"given":"Virginia Riego","family":"del Castillo","sequence":"additional","affiliation":[{"name":"Department of Mechanical, Informatics and Aerospace Engineering, Universidad de Le\u00f3n, 24071 Le\u00f3n, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0760-1170","authenticated-orcid":false,"given":"Lidia","family":"S\u00e1nchez-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Mechanical, Informatics and Aerospace Engineering, Universidad de Le\u00f3n, 24071 Le\u00f3n, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,21]]},"reference":[{"unstructured":"(2024, November 05).
