Asset management firm Lazard has a fascinating new analysis of renewable and other energy prices out. There are a huge number of insights in this, from an outside analyst whose primary interest is financial. First, the plunge in renewable prices continues, and over the last 5 years, wind has resumed its plunge as well.
Here’s the same chart from Lazard above, but with my annotations of the wholesale peak and baseload prices in the US.
Fortunately, as I’ve written before, energy storage prices are dropping exponentially.
In the long term, solar appears on path to be the cheapest source of energy in most parts of the world while the sun is shining, and storage may well become cheap enough to facilitate its use even at non-sunny times.

Please keep this discussion focussed by following the guidelines at the bottom of this article.
Internalized costs are the costs which can be accurately accounted for in our current systems. This article will cover two battery-based energy storage solutions: standard batteries and flow batteries. Germany currently offers a good example of the type of buy-sell spreads available in a system with substantial intermittent renewable energy penetration. An important feature distinguishing batteries from other energy storage technologies is that storage capacity (kWh) is generally the economically limiting factor instead of output capacity (kW). In addition to cycle frequency, cycle depth is also an important parameter in battery storage.
Another factor to take into consideration is that depth of discharge is often an important determinant in battery lifetime where shallower cycles can significantly prolong battery life (see above).
Finally, it must be acknowledged that there exists substantial uncertainty regarding the economics of pre-commercial energy storage technologies like batteries.
Even though Li-ion batteries are making all the headlines, most deep-cycle batteries for renewable energy application are still based on mature lead-acid technology. The breakeven electricity price spread for lead-acid batteries is given below as a function of the average depth of discharge and the capital costs.
Given that most suppliers recommend a maximum depth of discharge of around 50%, it is clear from the above figure why deployment of lead-acid batteries for energy storage is very limited.
This spread will further increase in the future, but will likely remain too small to drive significant deployment for the foreseeable future in the absence of subsidies which are substantially more lucrative than those currently in place. Flow batteries, Vanadium Redox Flow Batteries (VRB) in particular, are attractive due to their very long lifetimes even under consistently high discharge depths, their good scalability, and their flexibility in managing power and storage capacity separately. The breakeven spread for VRBs is given below as a function of the capital costs and depth of discharge. When considering that VRBs can be discharged to 95% without any significant ill effects on lifetime, the figure above starts to look somewhat more promising. REBUTTAL: If you strongly disagree with an existing DATA comment, please write a short rebuttal. CORRECTION: If you see a serious error in the numbers presented in the above analysis, please correct me so that I can correct the article. Make sure your comment gives only one piece of information (use multiple comments for multiple pieces of information). Externalities, potential technological breakthroughs and other energy options are off-topic. Schalk CloeteI am a research scientist searching for the objective reality about the longer-term sustainability of industrialized human civilization on planet Earth. In my view, the best way to use batteries for arbitrage is to time the charging of electric car batteries where possible to support the requirements of the grid. Electric car batteries can even offer short term support to the grid by supplying power at times when market prices are exceptionally high. Pure arbitrage using either Lead Acid or Lithium Ion technology – where the batteries do not have an additional function for the moment looks too expensive to make a commercial case.
Where penetration of intermittent wind and solar generation is relatively low, off peak periods will coincide with the night time period so night time charging suits the grid very well.
In areas such as Germany, parts of Australia, and Hawaii levels of solar installation are now such that on sunny days, off peak periods can now occur during the day.
Most vehicles are driven only for a relatively short period of time each day with the biggest journey being the daily commute to work. The company promised to build a state-of-the-art clean coal-fuelled electric power plant for $2.4 billion, originally scheduled to begin operation this month.
This ultra-modern power plant would capture 65% of its carbon dioxide emissions and pipe them deep underground into oil wells to aid in the extraction of harder to reach oil deposits.
The technology is so new that the industry doesn’t quite have its act together just yet. What makes the Kemper County clean coal power plant’s outcome so crucial is that the plant is being used as a poster child for a new environmental initiative to reduce greenhouse gases in the generation of electricity.
Kemper’s 582-megawatt capacity puts its original construction cost at $4,124 per kilowatt capacity.
The problem with capturing carbon dioxide gases is that the particles are much too small for the typical screens and filters that are currently being used to filter other particles, such as mercury and sulfur.


A joint research project between a Chinese power company, Huaneng, and the government’s Thermal Power Research Institute is already declaring victory in being able to capture carbon emissions for just $16 per ton of gas.
But after four years of continuing experimentation, we’re still no closer now than we were then. With few options available for capturing carbon dioxide cost-effectively, coal plants will have to be creative and find other means of covering their costs. But for this to be effective, an entirely new pipeline network would be required, as most coal plants are not conveniently situated next to depleted oil wells in need of that extra flushing power. So even when the industry has found a means of offsetting its carbon capture costs, getting all that infrastructure in place is going to cost even more.
Why are we jumping through hoops in an effort to make a dirty power source cleaner when there are plenty of cleaner power sources already available — and at a much cheaper cost? Understand that I'm not knocking coal, and I think efforts to regulate emissions on coal while not regulating dozens of other major sources of CO2 is further proof that the government can't break its habit of picking winners and losers. It's the reason we continue to subsidize the hell out just about everything, thereby buying into the illusion that the price we pay for our electricity or our transportation fuel represents the actual cost of production, distribution, and consumption. If you're looking for an easy way to play the modern energy space, look no further than energy efficiency. It's not an ordinary metal, but lithium demand is booming all over the world, driven by Tesla's life-changing innovations in technology.
Energy and Capital has collected some of the most highly touted energy experts in the industry. If you're ready to take control of your investments and ride Tesla's surging lithium revolution to higher profits, you NEED to read this report. In the past year we have seen an explosion in home solar panel leasing companies who provide panels at little to no cost.
Think of this like backfeeding the electricity grid with clean solar energy so the electricity company can reduce the amount on energy they need to produce from coal power plants. The solar company then subsidizes the cost of the electricity coming into your home saving you hundreds of dollars a year. In order to lower our dependence on fossil fuels, we as a state, must begin to shift to more renewable energy sources. However not everyone is so eager to lift the metering cap or to expand our state’s solar energy production. Unfortunately for the Granite State, she’s not the first GOP gubernatorial candidate to try to kill renewable energy investment. Manchester Mayor Ted Gatsas shares Forrester and Sununu’s opposition to renewable energy.
In addition, 20 projects that originally provided proposals but were not selected will be given the opportunity to update and resubmit their pricing proposals.
Under PUC rules, Hawaiian Electric normally must use competitive bidding to select generation projects larger than 5 megawatts. Their numbers show an average price decline over the last 5 years of 78% for utility scale solar and 58% for wind. The range shown reflects the range of geographies – from windy areas to less windy, from sunny areas to less sunny.
In particular, all comments comparing energy options like nuclear and renewables are off-topic.
In energy production, these costs typically consist of capital costs, financing costs, operation and maintenance costs, and exploration costs.
Three currently mature energy storage technologies – backup thermal power, pumped hydro storage and compressed air energy storage – were covered in a previous article, while synfuels will be covered in the next article.
As discussed in the previous article, the most important factors influencing the economics of specialized energy storage technologies are the capital costs and the capacity utilization. This implies that a limited battery storage capacity must be utilized at as high a frequency and discharge depth as possible, while facilities like pumped hydro where storage capacity is not such a limiting factor are free to cycle over longer timespans. As can be seen, significant spreads exist between weeks with high wind output and low wind output as well as between weekdays and weekends. Since the availability of high frequency spreads will vary significantly from one day to the next depending on fluctuations in renewables output and local electricity demand on weekly and seasonal timescales, the economically viable depth of discharge will also vary significantly.
Numbers utilized in this article are guided by data available from the reviews of Duke University, the IEA and DNV.
Standard batteries are especially attractive to advocates of distributed renewable energy because they can be deployed on small scale. However, sufficient subsidization could make batteries a viable option for early adopters in countries where household electricity prices are exceedingly high and feed-in tariffs are being reduced to limit deployment. They are generally not suitable for small-scale applications, however, and are therefore targeted more towards grid-scale energy storage. Naturally, the average depth of discharge achieved in practice will be much lower than 95%, but this will still improve the economics of VRBs relative to lead-acid and Li-ion batteries which should not be discharged beyond 50%. Of particular interest is good data on the capital, BOS and O&M costs of various battery types. Issues surrounding energy and climate are of central importance in this sustainability picture and I seek to contribute a consistently pragmatic viewpoint to the ongoing debate. Balancing services – energy storage can be used to rapidly respond to voltage or frequency variation or grid instability a service which can have considerable value. Black start – many traditional generators need some power to manage their ancillary systems during start up.


UPS – some users such as hospitals, air traffic control, data centres, banks, etc require or can benefit from UPS services. Likewise, in Denmark, wind power can generate an off peak period at any time of day or night. For the same price as 1 kWh by clean coal, you can get 1.67 kWh by geothermal with only 10% of the emissions. Eager to gain the upper hand over its Western rivals in science and technology, the Chinese government is funding extensive research into the challenge. You have to wonder if clean coal carbon capture plants are really worth it, given the cheaper alternatives that are already reducing CO2 emissions without requiring any additional infrastructure investments. And it's you, dear taxpayer, who's left on the hook for every single government failure that keeps us reliant upon inferior forms of electricity generation, transportation fuels, and technology. But the company behind it may fall flat, not because the technology isn't relevant, but because the goal is simply unreachable. Get the real facts on how bad student loans have become in our new bonus report "Digging Into Debt: How Student Loans are Burying Borrowers". Continuing to expand our renewable energy production will be a major issue for the next Governor.
This is an exciting step in the right direction for renewable power and a great boost to our state’s growing clean-energy industry. Hawaiian Electric's goal is to have as many of these projects as possible in service by the end of 2015. If those projects meet lower pricing and other criteria such as site control, they could be considered in a supplemental request to negotiate power purchase agreements. Hawaiian Electric narrowed the responses to five projects based on prices and other criteria such as site control and development experience. To accelerate the benefits of these low cost projects to customers, Hawaiian Electric is asking the PUC to waive competitive bidding for these five projects. Some energy options incur these costs in various stages such as extraction, transportation and refinement. Capacity utilization is an especially important issue in energy storage because of a trade-off between capacity utilization and the spread between the price at which the storage facility can buy and sell electricity.
These spreads are not economically accessible to battery technologies which should be cycled very frequently (at least once per day) to more economically utilize the limited storage capacity. For example, batteries could be useful in Germany over summer when solar PV creates a reasonably reliable daily cycle, but will be of very limited use in winter when solar PV output is minimal and more unpredictable wind power dominates. For example, reported Li-ion battery lifetimes range from 1000-10000 cycles and 5-15 years. Various literature sources were also consulted to confirm that data in these reports is reasonable (Mahlia, Chen and Gonzalez).
Balance of system and O&M costs are not often considered, but, just as is the case with solar PV will probably become a very important factor as battery prices fall. That being said, however, VRBs remain several times more expensive than pumped hydro storage analysed in the previous article even under the most optimistic cost assumptions. My formal research focus is on second generation CO2 capture processes because these systems will be ideally suited to the likely future scenario of a much belated scramble for deep and rapid decarbonization of the global energy system. And it is imperative to the future growth, prosperity, social stability, and security of nations around the world.
They do this by collecting energy from your rooftop panels and selling it to the electric company. After power purchase agreements are negotiated, each one must be submitted to the PUC for individual review and approval before it goes forward.
And so long as there is demand for more energy at the hours at which solar and wind are delivering (which is the case right now), then the situation is great. Profits and taxes are excluded wherever possible in order to isolate the pure cost of production. At higher capacity utilizations, the initial capital investment will be better utilized, but the spread between the buying and selling price will also reduce.
In contrast, a pumped hydro facility with a week or more worth of storage capacity can take advantage of these spreads. At one cycle per day, 10000 cycles will take 27 years to complete implying that age-related degradation would probably have rendered the battery unusable long before the cycle lifetime is over.
These costs are taken on the lower edges of the ranges given in the Duke University review. In exchange, Li-ion batteries offer longer lifetimes, lower maintenance requirements and higher round-trip efficiencies.
As the electric car market grows, this measure supported by smart charging technology can offer a very substantial battery resource with minimal additional capital expenditure.
