New Mexico and Tennessee Utilities Plans for New Solar, Gas Infrastructure, and Storage

New Mexico and Tennessee are on the verge of releasing the plans of putting new solar, gas infrastructure and storage. The source confirms that the proceedings of New Mexico are quicker than Tennessee as it is linked to the closure of San Juan Coal Power Station in June 2022.
Moreover, 280MW of gas peaker plants, 130MW of battery storage, and 350MW of solar results of PNM’s modeling. With the comparison to the continuation of operations at San Juan, it anticipates saving customers US$7.11 per month in 2023.
Recently, the Tennessee Valley Authority (TVA) filed an Integrated Resource Plan. The Utility’s 20-year plan includes up to 2.4GW of energy storage by 2028 and up to 5.3GW by 2038. It also reaches a range of 1.5-8.0GW of new solar capacity by 2028 and 14GW by 2038. The energy storage pipeline absolutely relies on the cost reductions accomplished in the industry. The IRP states, “The trajectory and timing of additions will be highly dependent on the evolution of storage technologies.”
Pat Vincent-Collawn, Chairman, President, and CEO of PNM Resources drops a statement that every individual step will be 100% emissions-free. This is advised to balance the cost, environment, and reliability. The San Juan plant will save customers money and stands one of the most extensive solar facilities in the US with the highest percentages of battery storage.
The combination of solar and storage is rapidly bringing up the competition with gas generation. The 2.2GW of coal capacity is considered for retirement. Moreover, Gas-fired additions are dependent on the scale of solar deployment with up to 8.6GW of peaker capacity. The sources also confirm that 9.8GW combined cycle gas could also be built by 2038.
