In 2010, the Arkansas government introduced an energy efficiency obligation for all sectors except transport, covering electricity and gas. The obligation seeks to achieve an energy savings of 249 GWh per year, and an incremental energy savings of 0.1% when compared to total fuel consumption. Obligated parties include electricity and natural gas utilities. For programme year 2015, the base year for measurement is 2013. The target for electric utilities is 0.90% of 2013 sales, and the target for natural gas utilities is 0.50% of 2013 sales. In 2018, the PSC adoped higher savings targets, raising the targets to 1.2% of baseline sales for electric utilities and 0.5% of baseline sales for natural gas utilities. Eligible energy efficiency measures include education, audits, heating systems, lighting, demand response, insulation, HVAC, and motors. Calculation of measures is based on deemed and metered savings. All programmes are subject to annual evaluation, measurement, and verification. Each utility employs a third-party contractor to perform company specific evaluation, measurement, and verification. The Commission's General Staff also contracts with an Independent Monitor who evaluates and verifies the work of the third-party contractors. Each utility files an annual evaluation, measurement and verification report with the Commission, and the Independent Monitor also files an annual report with the Commission.
