Glasgow Electric Power Board (EPB), one of the Tennessee Valley Authority‘s member utilities, has established a reputation of being a thoughtful and forward-looking company. For nearly two decades, Glasgow EPB has been a leader in the deployment of smart grid technologies and practices. For example, in 2007, Glasgow EPB began installing fiber-based broadband to all [...]
With the defeat of the utility-sponsored anti-solar Amendment 1 in Florida, we are wondering what the utilities’ next step will be. Will they engage with stakeholders to put more sun into the Sunshine State? If they don’t – we can expect more scapegoating of rooftop solar. The technical foundation was recently laid out in a [...]
Wind resources from western Oklahoma and Texas – where the Clean Line and Pattern Energy transmission line projects will source wind – are being marketed at prices around $20-30 per MWh. That’s comparable to the price of operating a modern natural gas power plant, making wind not only cost-effective but a guaranteed low-cost electricity source for decades in the future.
What happens when temperature doesn’t change very rapidly? People can be unaware of a 8 ºF change in temperature as long as it occurs over at least 8-10 minutes.
So under NC-REPS, avoided costs are recovered in one tariff (a legal document that connects cost recovery to customer bills) and the remaining revenues needed for renewable energy are recovered in another tariff. So regardless of whether the project is contracted under PURPA or not, the costs have to be split up into two buckets, PURPA and “all the rest.” It is literally extra work for everyone involved to NOT use the PURPA rate in North Carolina.
From Colorado to the Southeast? A major settlement on vexing renewable energy issues has just been announced in Colorado that has important implications for the Southeast. On August 15, a major settlement was announced between Xcel Energy, the staff of the Colorado Public Utilities Commission, and numerous businesses and associations in Xcel Energy’s rate case. [...]
Really, it is time to buy wind energy. This is very simple. Wind costs less than running natural gas power plants. Keep the power plants. Use them, we’re not saying they aren’t needed. But it is cheaper to buy power from wind projects than to run your power plant full-out. Look at this amazing forecast [...]
Our followers on social media think the answer should be “as much as possible,” but in our brief SACE argues in favor of a cap of 2,500 megawatts (MW) of renewable energy, likely to be mainly solar and wind. Georgia Power has proposed only 525 MW, and other parties have signaled interest in 1,200 MW or 2,000 MW. What’s remarkable about this “debate” is that everyone involved agrees that whatever the number, Georgia Power customers will end up saving money as these projects will cost less than the projected cost of generating power. This approach to developing renewable energy has been led by Commissioner Bubba McDonald.
Where’s the best place for solar energy? It may not seem obvious to many readers, but Memphis, Tennessee is one of the smartest places to put solar energy in the Southeast. Just this week, TVA showed how it is following this kind of smart siting by signing a a 53 megawatt (MW) solar facility power purchase agreement (PPA) with Nashville-based renewable energy provider, Silicon Ranch Corporation, to construct what will be Tennessee’s largest solar array in Millington, TN, just north of Memphis.
What’s so smart about putting solar in the western part of TVA’s service territory? It turns out that on hot summer days, TVA can rely on the sun shining on West Tennessee and Northern Mississippi late into the day – producing solar energy just when air conditioners across the entire Tennessee Valley most needs this clean energy to keep folks cool.
What’s the single largest source of CO2 emissions in the Southeast? A 10 million ton data discrepancy! What? Huh? Why is a data discrepancy a blog? (UPDATE: Please see responses to reader suggestions at at the end, as well as in the comments.) President Obama’s Clean Power Plan will eventually regulate the emission of carbon [...]
