A reliable, cost-effective power supply is critical to the economic viability and the overall quality of life in Memphis and Shelby County. As the utility company that serves this community, MLGW wants to ensure we are providing the most reliable and affordable power available. To meet these goals, Memphis Light, Gas and Water embarked on an extensive evaluation of power supply options. We sought public opinion, input from civic and local business leaders and expert advice from third-party consultants.

IRP Timeline

2020 – With help from Siemens International Inc., MLGW put together an Integrated Resource Plan (IRP). The IRP considers the power supply options and weighs which ones would best fulfill the needs and wants of our community. A comparison of multiple portfolios and their expected performance under different scenarios found that a select group of portfolios performed better more often.

Upon its completion, the IRP recommended MLGW undertake a Request for Proposal, or RFP, to confirm any potential savings.

2021 – MLGW plans to issue three RFP’s by summer 2021.
  • A transmission solution RFP.
  • A thermal generation or purchased power agreement (PPA) RFP.
  • A renewable/other generation PPA RFP.

Late 2021 to early 2022 – Responses to all RFP’s expected.

2022 – An evaluation of the bids returned with each RFP will likely take up most of 2022. Once bids are chosen they must be presented to the MLGW Board of Commissioners and ultimately the Memphis City Council before any contract is awarded.

How Did We Get Here?

Studies commissioned by MLGW and outside organizations show potential financial savings tied to the seperation of MLGW and the Tennessee Valley Authority. You can read the different studies here. 
What is an IRP?
An integrated resource plan, or IRP, is a comprehensive view of what a utility needs to continue providing energy to its customers. A utility must consider: how many customers will we serve? What happens if a power supply plant goes down? Are state or federal regulations changing? The list goes on. Utilities use what they learn to create a roadmap for the future of the company.
MLGW customers, Board of Commissioner members, industry experts and members of a Power Supply Advisory Team (PSAT) weighed in on what they think the future of the power supply should be.
