Table of Contents gas to MPS began in the second quarter of 2019. Under this contract, intrastate gas supply is sourced in the same manner as interstate gas through a variety of medium and short-term purchase contracts. To supplement its own generation and operating reserve requirements, and to meet its Renewable Portfolio Standard ("RPS") requirements, the Company engages in power purchase arrangements that may vary in duration and amount based on an evaluation of the Company’s resource needs, the economics of the transactions and specific RPS requirements. The Company has a firm 100 MW Power Purchase and Sale Agreement ("Power Purchase and Sale Agreement") with Freeport-McMoRan Copper and Gold Energy Services LLC ("Freeport"), pursuant to which Freeport delivers energy to the Company from the Luna Energy Facility (a natural gas-fired combined cycle generation facility located in Luna County, New Mexico) and the Company delivers a like amount of energy at Greenlee, Arizona. The Company may purchase up to the contracted MW amount at a specified price at times when energy is not exchanged under the Power Purchase and Sale Agreement. The Power Purchase and Sale Agreement was approved by the Federal Energy Regulatory Commission ("FERC") and will continue through an initial term ending December 31, 2021, with subsequent rollovers until terminated. Upon mutual agreement, the Power Purchase and Sale Agreement allows the parties to increase the amount of energy that is purchased and sold thereunder. The parties have agreed to increase the amount up to 125 MW through December 2021. The Company has entered into several power purchase agreements to help meet its RPS requirements. Specifically, the Company has a 25-year power purchase agreement with Hatch Solar Energy Center I, LLC for a 5 MW solar photovoltaic project located in southern New Mexico, which began commercial operation in July 2011. In June 2015, the Company entered into a consent agreement with Hatch Solar Energy Center I, LLC to provide for additional or replacement photovoltaic modules. The Company also entered into a 20-year contract with Solar Roadrunner, LLC, a subsidiary of Global Infrastructure Partners, (formerly known as NRG Solar Roadrunner LLC) for the purchase of all of the output of a 20 MW solar photovoltaic plant built in southern New Mexico, which began commercial operation in August 2011. In addition, the Company has 25-year power purchase agreements to purchase all of the output of two additional solar photovoltaic projects located in southern New Mexico, SunE EPE1, LLC (10 MW) and SunE EPE2, LLC (12 MW), which began commercial operation in June 2012 and May 2012, respectively. In September 2017, Longroad Solar Portfolio Holdings, LLC purchased SunE EPE1, LLC, and in October 2017, Silicon Ranch Corporation purchased SunE EPE2, LLC with the Company's consent per the terms of both power purchase agreements. Furthermore, the Company has a 20-year power purchase agreement with Macho Springs Solar, LLC to purchase the entire generation output delivered from the 50 MW Macho Springs solar photovoltaic project located in Luna County, New Mexico, which began commercial operation in May 2014. Finally, the Company has a 30-year power purchase agreement with Newman Solar LLC to purchase the total output, which is approximately 10 MW, from a solar photovoltaic generation plant on land subleased from the Company in proximity to Newman. This solar project began commercial operation in December 2014. Other purchases of shorter duration were made during 2019 to supplement the Company's generation resources during planned and unplanned outages, for economic reasons and to supply off-system sales. The Company concluded and announced its selection of resources from its 2017 All Source RFP on December 26, 2018. In addition to conventional natural gas generation, the Company initiated contract negotiations during 2019 for power purchase agreements from both solar and battery storage resources. On November 18, 2019, the Company filed for regulatory approval with the NMPRC for three power purchase agreements relating to both solar and battery storage resources as a result of the Company's 2017 All Source RFP. 9 Purchased Power
