Comment on “Renewables May Become the Netflix of the Energy Sector” | Greentech Media

The analogy to Netflix is fascinating. As GTM points out, Netflix started out competing with Blockbuster in video DVDs, but then spilled over into video streaming (BTW, a market that Enron famously thought it could corner in the last 1990s.) So Netflix is now competing with both cable and broadcast companies. One can see how renewables could jump out of just electric service to building space conditioning and water heating, and vehicle fueling. Tesla is already developing those options.

Clean energy too big to be shut down by Trump – San Francisco Chronicle

I’ve been struck by the lack of panic in the energy industry about President Trump’s decision. This article goes into that underlying confidence that the momentum appears unstoppable.

WASHINGTON — President Trump’s decision to abandon the Paris Accord will slow the battle against climate change in the U.S., but there’s too much momentum in the nation’s clean-energy economy to shut it down, energy experts say.

Problems with “Residential storage can undercut benefits of rooftop solar, says new study” | (A response to a Utility Dive article)

A new study in Nature Energy finds storing rooftop solar can increase emissions and energy consumption.

My thoughts: Here’s the key statement for the finding in this report: “based on today’s Texas grid mix, which is primarily made up of fossil fuels.” If the either the marginal generation on the grid is low or no GHG (e.g., renewables overgeneration which is an increasing problem in California) or the connection to the grid is cut or restricted (e.g., in a microgrid), then this premise doesn’t hold.

This study relies on fossil fueled generation being the marginal energy source. It also focuses solely on operational changes with existing resources. The appropriate frame is looking at the change in generation investment with and without storage, so for example more renewables become cost effective with storage so the overall generation mix changes.

The second problem is that most of the production cost models are yet incapable of capturing reduction in flexible capacity use. That’s why the California Energy Commission has had DNV and LBNL working on modeling those resources. So the emission savings are underestimated.

The third problem is that savings in residual unit commitment (RUC) is underestimated in the models. These are gas units running on standby with no-load, to be available the next day for ramping, load following or reliability. Storage reduces the need for these resources as well. NREL recently released a study on the value of storage that captures this benefit.

If these findings are valid, then the existing Helms pumped storage plant is also increasing GHG emissions. One could go so far as to say that the value of pondage hydropower storage may be so diminished that relicensing conditions that require run of river operations may have little effect on costs and GHG emissions.

Big Business Is Killing Innovation in the U.S. – The Atlantic

How big business and overconcentration jams the wheels of innovation in the U.S. This is particularly relevant to encouraging new distributed energy resources on the electric utility grid–the poster child for monopolies.
