| Description: | Write diagnostics for LT Plan Company Levelized Costs |
Diagnostic Levelized Company Costs triggers the CSV summarisation of each Company's levelized cost of energy (LCOE) within LT Plan.
LCOE provides high level financial insight into capacity expansion projects consisting of many different PLEXOS objects (i.e. several renewable Generators firmed with Batteries). It is useful for Power Purchase Agreements (PPAs), Round-the-Clock (RTC) renewable energy valuation and Firm & Dispatchable Renewable Energy (FDRE) contexts.
LCOE is calculated by accumulating and discounting the energy (Net Generation) and costs (Total Cost, Build Cost, FO&M Cost etc.) generated & incurred by each asset owned by a Company. Discounting and accumulation is applied to the following collections:
For a single asset, discounted generation in year n is given by Net Generationn / (1 + r)n, where r is the effective discount rate. This is the LT Plan Discount Rate or asset-specific WACC (i.e. Generator WACC) if one has been defined. Discounted costs are accumulated similarly, i.e. (Total Costn + Build Costn + FO&M Costn) / (1 + r)n in year n for each asset.
Total costs and generation are accumulated and discounted over the entire Planning Horizon. This is performed for each asset and each company in each capacity optimization period (i.e. year). A whole-of-planning horizon LCOE os then given for each Company. Explicitly, this is the ratio of summed & discounted costs to summed & discounted generation.
The partial ownership of assets by a Company (i.e. non-unity Share) is supported.
