Energy Accounting

Energy Accounting is an emerging international standard for reporting performance based on the observed Operating Model. Energy Accounting is emerging from work led by the Sandia National Lab’s affiliated Photovoltaic O&M Analytics Collaborative (PVMAC) and global industry contributors. Energy Accounting is constructed around the GAPP (Generally Accepted Performance Principles) framework, analogous to Financial Accounting. Energy Accounting improves project reliability and predictability by addressing historic barriers between financiers, owners, and operators.
