The reporting on renewables is getting more focused and less “breathless” as this article exhibits, and it is actually good to see state regulators are considering restricting some renewables construction and siting due to environmental concerns. A good two minute read.

The transmission projects support New York’s clean energy goals, but NextEra Energy Resources’ 180-MW North Side solar farm was rejected over environmental concerns.

It is time to begin to think rationally vice politically about a conversion to renewable generation for the US grid. This challenge is more complex than any politician understands and it requires engineers of many disciplines to apply their skills to answer the challenge. Texas, with its ERCOT independent grid, might just be the right place to start as it operates apart from regional and national constraints. It could be the perfect laboratory to craft a blended solution - one that withstands weather episodes. In an expanse as broad as the US, and considering its variety of prevailing weather patters, regional demand factors, population distribution, etc. etc., it's time we have meaningful discussions about the role of nuclear power, gas generation, renewable generation, behind the meter microgrid integration and energy storage technologies. It is time to dismiss the foolhardy belief the US will be 100% renewable any time soon and get busy with designing and building solutions that solve today's issues and form the foundation for tomorrow's grid.

Another state where unreliable renewable energy leads to power outages.

In order for the US to transition away from carbon emitting rotational generation to one comprised of a number of renewable technologies plus hydro, plus some cleaner rotational sources, we will need to embrace battery storage systems in a big way. This two minute article here gives a great introduction to storage system technologies, their features and their benefits. There is one discrepancy in the article and that is the author makes a generalization that energy is stored during hours of low energy demand (and cost) to be used later when energy costs are higher. The fallacy is that in areas of predominately solar generated power, the time of peak demand (daylight hours) is also the time that the batteries have to be charged as the solar panels generate nothing after dark during low demand periods. Aside from that, the article provides some insight into the various uses for the stored energy.

Without energy storage, electricity must be produced and consumed exactly at the same time.

Are you on board yet? The attached article posits an interesting question. "When will you make the decision to consider an electric vehicle?" Will it be when the US has sufficient high speed charging stations? Will it be when the average vehicle costs is significantly less that $66k? This is an interesting 2 minute read addressing a couple of questions like this.

They could go from niche product to mass adoption in a matter of years.

Great article about how the role of traditional natural gas generation will play in our transition to cleaner, renewable energy technologies.

Key metrics tracking outages and unserved energy demand spiked in 2021, according to the North American Electric Reliability Corp.

It was recently reported that due to a high pressure system over Texas, winds were not blowing and the windmills there were producing only 8% of their capacity. This put Texas and the ERCOT grid into a situation that could necessitate rolling brown outs. One solution to problems like this that plague markets with high percentages of power generated by renewable technologies is the use of battery storage systems. Long used behind the meter for rate arbitrage, front of meter BESSs also have a role in supporting the grid by supplying power (previously generated and stored) in response to periodic demand spikes.

The increase in storage capacity was accompanied by changes in how the batteries are used, with applications shifting away from traditional ancillary services.

The "devil is in the details". This article from highlights a challenge facing EV owners and even more specifically EV charger manufacturers and EV charging service providers. While politicians blithely proclaim "we'll be carbon free by 20XX" they are completely clueless as to the challenges the engineers and builders of the systems will face. This article is worth the 3 minute read if for nothing else but to splash a little cold water on the face to alert us to one of many second and third order effects of politically expedient decisions.

Flow batteries, Behind the Meter, Power arbitrage, Renewable pairing. With new technologies comes new vocabulary. The worldwide effort at incorporation of renewable energy resources demands we become at least familiar with the lexicon of the new power utility paradigm. This excellent article (2 minute read) by Burns & McDonnell describes in easily understood detail, energy storage technologies that we all will encounter and perhaps consider over the next 5 to 7 years. I have long advocated that when it comes to batteries/energy storage, one size does not fit all. Lead acid batteries will have a place in the market at least for few more decades. Lithium seems to have hit its stride. Flow batteries are showing promise. And, there are other technologies on the horizon. A power grid with a significant percentage of renewable generation implies there will be battery energy storage coming to a location near YOU! Can't you just hear the NIMBY (not in my back yard) comments at the local planning/zoning board hearings about locating an energy storage installation near a school or playground? We heard all this with cell tower placements in the 90s. This is version 2.0. Stay tuned........it's about to get interesting!

As more renewable power is connected to the grid, battery installations are becoming the go-to storage solution. Lithium-ion technologies lead the way.

In this article, a case is made for nuclear power generation to be a key component of base load generation which, if properly developed and integrated with renewable generating sources will go a long way to reduction of carbon emissions. However, one key take-away from the article is a topic that has been haunting the US for 20+ years and that is the shortage of skilled workers, in this case welders! Trade and Vocational schools have not been in vogue for the last couple decades among education's hierarchy. That decision to eliminate such educational choices was erroneous at best and now the results have come home to roost. The re-vamp of our electric grid will only amplify the problem. The next 20 years will be interesting and full of opportunities for those paying attention.

Western countries are making big bets on nuclear energy to help tackle climate change and reduce dependence on Russian oil and gas, but are short on experience in building the plants after shunning them for years.

A interesting article discussing New York State's current power generating reliability margins in a recent Utility Dive issue. Of particular note is the section identifying the seasonal demand shift from summer to winter as New York prepares to electrify buildings and its transportation sector, adding significant load and ultimately shifting to a winter-peaking system. There is still one major issue that designers and engineers need to address, that is the challenges to charge battery storage systems in sub-freezing weather. From Western New York across the state and into the Adirondacks, extended periods of sub-freezing and even sub zero temps are common. These conditions challenge current Lithium battery charging.

Reliability margins on New York’s grid are shrinking, the Independent System Operator said, just days after state lawmakers halted work on a bill designed to grow renewables.

This article highlights the now proceeding rollout of 5G at and near major airports. This is welcomed news to families sitting in airports or business travelers looking to conduct meetings from inside terminals as the 5G service supports applications with greater bandwidth requirements, but the rollout is not without critics who voice safety concerns. From our perspective, the power requirements associated with 5G transmission infrastructure translates to additional power plants and standby battery systems - a silver lining behind a grey cloud from our perspective.

The wireless carriers said they would slowly lift self-imposed limits on their network expansion this year, though a major airline group said airlines wouldn’t have enough time to retrofit aircraft under the planned timetable.
