Task: Formula-prediction-context (source dataset: pge-random)

You are given an table region extracted from a real Excel spreadsheet, which is centered around a cell called "Target Cell" (labeled as "[Target Cell]" shown in the table below). The table region below includes up to 10 rows above/below the Target Cell, and 10 columns to the left/right of the Target Cell. 

Your task is to analyze the table context surrounding the Target Cell, and predict the most likely Excel formula that should go in the Target Cell. If multiple formulas are possible, choose the most reasonable or commonly used based on context.

1. Please follow the standard formula syntax in Excel, e.g. always begins with an equal sign (=).
2. Base your predicted formula on the surrounding table context, e.g., column headers, annotations, and data values in nearby cells.
3. No explanation — just output the formula itself in a JSON format: {"formula": "your_formula_here"}.

| 72 |     | * One of the two price sources used to derive the historical heat rate component, Platts Megawatt Daily, was discontinued as of December 1, 2014. The remaining index, CAISO Integrated Forward Market (IFM) NP-15 Data, will continue to be used as the “equivalent successor” of the former price source.  Previously, two price source substitutions were made in the annual heat rate adjustment calculation: (1) CAISO day-ahead NP-15 trading hub LMPs (TH_NP15_GEN-APND) were used in lieu of day-ahead NP-15 pricing from ICE; (2) ICE natural gas forward basis prices (for PG&E Citygate) were used in lieu of basis prices from NYMEX Clearport.  These substitutions were made due to substantial illiquidity and missing prices in the sources previously employed. |     |     |     |     |     |     |     |       |       |     |
