; or (ii) electricity demand; (B) the representativeness of the data, with a goal to approximate actual conditions as closely as reasonably possible with representativeness validated and uncertainty quantified; (C) the spatial resolution of observational data, with a goal to provide weather data over a grid with 2 kilometer spacing or smaller; (D) the frequency of the data, with a goal to report weather data not less frequently than hourly, and preferably every 15 minutes; and (E) the duration of the data, with a goal for the data to be— (i) chronologically consistent, complete, and span at least a 30-year period; and (ii) updated periodically, as determined by the Secretary. (3) Potential data needs In identifying and analyzing relevant data under subsection (a), the Secretary shall consider potential future needs, including— (A) emerging technologies that employ machine learning or artificial intelligence for the purposes of improving— (i) the reliability and resilience of the electric grid, especially in rural areas, low-income communities, disadvantaged communities, and energy communities; and (ii) long-term reliability assessments, resource adequacy models, and integrated resource planning; (B) the changing mix of energy generation resources and demands on the electric grid, including energy efficiency as a resource; (C) the security and costs associated with collecting and sharing those data; and (D) ways to mitigate risks and cost impacts to utilities associated with data collection and sharing. (4) Methods and platforms In identifying and analyzing relevant data under subsection (a) with consideration of the factors described in paragraphs (1) through (3), the Secretary shall consider the available methods and platforms for acquiring and sharing the data, including— (A) existing surveys, such as the surveys carried out using Form EIA–861 of the Energy Information Administration; (B) existing data sharing platforms, such as— (i) the Open Energy Data Initiative of the Department
