Legislative activities

While the Tennessee state legislature has not yet approved any laws specifically addressing smart grid, as early as 1979 it has looked into some distributed generation technologies and created contractual methods for entering into solar easements for solar energy systems. [2]


Regulatory activities

The majority of rates that have an impact on smart grid come from Entergy Arkansas, however Entergy Arkansas only serves approximately twenty-two accounts in Tennessee. The Tennessee Regulatory Authority will often have a docket to review and approve what the Arkansas Public Service Commission has already decided. The Tennessee Regulatory Authority approved Time of Use for both business and residential customers by 1992., By 2007 they had reviewed distributed generation, including net metering, and demand-side management. [3, 4, 5, 6]

“To consider adoption of PURPA Standard 14 (“Time-Based Metering and Communications”) as enacted in EPACT 2005, the Tennessee Regulatory Authority held separate proceedings for Entergy Arkansas, Kentucky Utilities, Appalachian Power, and Kingsport Power. Ultimately, in each of the proceedings the Tennessee Regulatory Authority decided not to adopt PURPA Standard 14:

- Entergy Arkansas: In January 2007, the Tennessee Regulatory Authority determined that Entergy Arkansas’s rates and services already met the standard set by EPACT 1252 so there was no need to adopt it.
- Kentucky Utilities Company: In January 2007, the Tennessee Regulatory Authority determined that Kentucky Utilities Company’s rates and services already met the standard set by EPACT 1252 so there was no need to adopt it.
- Appalachian Power: In August 2006, the Tennessee Regulatory Authority determined that Appalachian Power’s rates and services already met the standard set by EPACT 1252 so there was no need to adopt it.
- Kingsport Power: In August 2006, the Tennessee Regulatory Authority determined that Kingsport Power’s rates and services already met the standard set by EPACT 1252 so there was no need to adopt it.” [1]

Time of Use rates break the cost for electricity into periods on a seasonal basis for energy and demand pricing with either on-peak or off-peak pricing, it also includes preferential rates for the customer shifting usage to off-peak time periods.

Distributed generators include small qualifying power production facilities and net metering where prices are based on the company's avoided cost or the energy is carried forward for billing purposes.

Demand-side management includes curtailable demand and interruptible service. Curtailable demand and interruptible service requires reducing consumption to attain a minimum level of consumption when called upon by the company to be credited a posted hourly price, during a contract time period.
