+### Daily Natural Gas Price Adjustments
+
+Daily gas price adjustments use degree day coefficients derived from an ordinary least squares regression regressing daily regional heating and cooling degree days on daily deviations of regional natural gas spot prices from their annual average price with monthly fixed effects.
+The regions used in the regression mostly correspond to census divisions, except in two cases where census divisions are broken up into two smaller regions.
+The Pacific census division is broken up into the subregions "Northwest" (Oregon and Washington) and "California" (California).
+The Mountain census division is broken up into the subregions "Southwest" (Arizona and New Mexico) and "Mountain" (all remaining states in the Mountain census division).
+
+To derive daily gas price adjustments, the regression parameters are applied to projections of daily heating and cooling degree days.
+These projections are derived by rescaling historical daily heating and cooling degree days (calculated using hourly average temperatures observed during the weather years corresponding to representative periods) to match projections of annual degree days.
+In cases where the regression regions correspond to census divisions, annual degree day projections are taken from AEO.
+Otherwise, annual degree day projections are calculated by taking historical (1995-2025) state-level degree days from {cite}`noaaDailyDegreeDays`, projecting them out to 2050 using a 30-year linear trend, and then aggregating them to the scope of the regression regions via population-weighted average.
+For purposes of calculating this population-weighted average, state-level population projections for 2030, 2040, and 2050 are taken from {cite}`uvaWeldonCooperCenterPopulationProjections` and in-between years are linearly interpolated.
+
+Depending on the spatial resolution of the gas prices being used in the model, the daily gas price adjustments are either downscaled to the zone level by copying each regression region's adjustments to their constituent zones or upscaled to the census division level via population-weighted average.
+Once representative periods are selected in the model, the daily adjustments are filtered to include only the representative periods and then renormalized so that the average price multiplier for each zone or census division and each model year is one, thus ensuring the year-round average gas price remains unchanged.
+{numref}`figure-natural-gas-price-adjustments` shows an example set of price adjustments including the national wintertime markup and daily adjustments for each census division.

   abstract = {We consider the problem of designing a new natural gas transmission network or expanding an existing network while minimizing the total investment and operating costs. We develop an integrated large-scale mixed-integer nonlinear optimization model to determine pipelines in the network, compressor stations and their capacities, timings of these installations in a multi-period planning horizon, and natural gas purchase and steady-state flow decisions for each period in the network. The model is solvable using state-of-the-art solution methodologies available online. Employing our modeling and the solution methodology for its solution, we conduct computational studies on various test instances generated using realistic network structure and data based on the natural gas network in Turkey as well as data from literature. Our analysis provides insights into sensitivity of network configuration and operations to the number of periods within the planning horizon and cost parameters as well as into strategic decision making for design and expansion of natural gas networks.}
