A Bright, Sunny Forecast for the Tennessee Valley

The Tennessee Valley Authority (TVA) is farsighted, not shortsighted, when it comes to its efforts to evaluate and plan for solar power in its future. The 2015 Draft Integrated Resource Plan (IRP) provides the clearest, sharpest look ever by a Southeastern utility at solar energy as a resource – and not a threat – to this amazing, clean energy opportunity.

Is TVA Undervaluing Wind Energy?

TVA recently released its Draft Integrated Resource Plan (IRP). An IRP is a planning exercise to determine utility power plant needs 20 years into the future. The exercise depends on inputs (such as cost and performance data for various power plant types, including wind farms) to develop outputs and recommendations. Some of TVA’s most important inputs for wind power are a bit opaque – especially cost and performance data. But based on the IRP outputs, it appears that the inputs for wind energy are stuck in TVA’s wind energy glory days and are about a decade out of date.

Massive Wind Power Opportunities for Tennessee

Tennessee is home to the Southeast’s first wind farm, the Buffalo Mountain wind project. This wind farm was installed nearly a decade ago and is still meeting performance goals and expectations. Several other wind farms have been proposed in Tennessee. Meanwhile, the Tennessee Valley Authority is currently purchasing over 1,500 megawatts of wind power from the upper-Plains states. High Voltage Direct Current (HVDC) transmission projects, like the Plains and Eastern project, would inject thousands of megawatts of new high quality, low cost wind power for the Volunteer State.

TVA 2015 Draft IRP Views Clean Energy Through a Blurred Lens

If you’re like me, you are nostalgic for the days when the Tennessee Valley Authority (TVA) brought innovation, increased economic development and low-cost energy to the Tennessee Valley.  TVA’s recently released draft 2015 Integrated Resource Plan (IRP) outlines five alternate energy scenarios under which TVA could implement various resource planning strategies to meet both short- and [...]

What have we learned in the four years since the Fukushima nuclear disaster in Japan?

Today marks the fourth anniversary of the devastating Great Japan East Earthquake and subsequent tsunami that killed many thousands of people, with thousands still missing, and triggered a triple-meltdown at the Fukushima Dai-ichi nuclear plant. A reported 250,000 people still remain displaced, with the Fukushima prefecture officially stating that over 118,000 Fukushima people are still [...]

Wind Power Transmission Project Would Provide Health Benefits

A newly proposed transmission project would connect high quality wind power to the southeast. The proposed Plains and Eastern Clean Line project would provide up to 4,000 megawatts of wind power from western Oklahoma and Texas to the southeast. The project is currently undergoing a federal Department of Energy Environmental Impact Statement (EIS) review process to evaluate potential impacts from the 720-mile high voltage direct current transmission project. Instead of focusing solely on negative impacts, the EIS also weighs a few of the benefits of the proposed project.

Kingston Residents Gather and Call for New Public Hearing on Proposed Coal Ash Landfill

Thursday night, February 5th, more than 30 local residents of Kingston, TN joined together at the Kingston Community Center to attend an event hosted by Statewide Organizing for Community eMpowerment (SOCM).  The purpose of the event was to [...]

TVA Announces New Energy Efficiency Program for Homeowners

Yesterday, TVA announced the unveiling of its new energy efficiency program, eScore. The new program provides homeowners with expert recommendations and instant rebates through installations to make their home as energy efficient as possible. The recommendations and instant rebates are grouped within 10 categories, targeting the major energy consumption in most homes. (The rebates available [...]

TVA Approves Shawnee Pollution Controls Instead of Retirement

On Dec. 30, during a special session of the Tennessee Valley Authority board, a decision was finalized to invest significant resources into retrofitting two units at its older, Shawnee coal plant in Paducah, KY. As explained in an earlier SACE blog, TVA had to make a decision concerning Shawnee Units 1 and 4 by December [...]

Decisions, Decisions at TVA’s Shawnee Coal Plant

As 2014 draws to a close, the Tennessee Valley Authority (TVA) has been busy working on making an important decision at its Shawnee coal plant in Paducah, KY.  December 9th marked the end of the public comment period for TVA’s draft Environmental Assessment (EA) to determine whether or not it should retire or retrofit two coal [...]
