Last week we framed the battery question in terms of dollars per MWh that would have to be earned in order to make the math work. Today's blog highlights the valuation techniques and results of battery optimization, whereas the EnergyGPS Special Report, titled 'Battery Modeling Using the TB4', dives into detailed analysis around battery optimimization.  The special report is included in the EnergyGPS Platinum Package we offer as part of our Newsletter Subscription (Monthly or Annual) or you can by the report a la carte ($500) by clicking on the link tied to the title. When Energy GPS looks at batteries we use a number of valuation techniques including examining regulating reserves payments, simple energy arbitrage payments in various markets, and a more complex forms ... » read more

In football, there are a handful of teams that always seem to walk into the month of November with this notion of not winning a game all season.  The Miami Dolphins came to mind in late October as they were actually winless in their first 7 games but have rallied to win 2 in a row.  The New York Jets team is flat out bad as their record is also 2-7 with a win earlier in the season before they fell on some hard times.  The Cincinnati Bengals are the prize jewel of the group this year as they are currently 0-9 while the Washington Redskins are 1-8.  As you can see from each team's record, the wins are few and far between with many winless in November. How does all this NFL talk translate to the energy markets you might ask?  The similarity is reflected in the actual ... » read more

Over the past few weeks, there has been a lot of chatter about the wildfires in California and the rolling blackout plan implemented by PGAE to mitigate equipment risk that has been deemed the cause of fires in previous years.  As part of the EnergyGPS West Power and Natural Gas product offering, we been monitoring both the supply/demand components that are being impacted.  On the demand side, the first set of cuts was impactful as over .8 GWa of electricity was taken from the grid with the peak hour hitting 1.1 GW.  The next two hours were slightly less impactful as the temperatures were already shifting to more fall-like weather but nonetheless, families and businesses were being displaced to other adjoining balancing authorities that were not tied to PGAE or driving to ... » read more

Over the past three weeks we have noticed a material change in the Alberta natural gas demand. This is highly unusual. Thanks to the build out in oil sands and a growing population the province has been booming for decades. In some years we have seen as much as a 1 BCF per day gain in the underlying demand. For the first time that we can remember the demand has started to shift down. We have to look no further than the Athabasca oil sands projects to find out why. A number of companies have announced layoffs and production cuts in an effort to shore up balance sheets during a difficult price environment. On top of it, thanks to a tight natural gas inventory issue, the AECO cash prices are running at multi year highs which constricts the production margins. Natural gas is a major input for ... » read more

If my computer screen was a television, you’d think that I have been binge watching the Storage Channel! You know, that new channel that everyone is talking about that includes stand-alone battery storage, solar plus storage, pump storage hydro, and even pushing trains uphill and harnessing the energy as they fall. This is especially true in the WECC as buyers run from the worsening duck curve, coal plants retire, and rumblings of the need to put a price on installed capacity work their way around western utilities. Figure 1 | Battery Storage on the Grid In today's blog we introduce a few of the concepts and data tied to battery storage.  These highlighted concepts will be broken down into more detail in an EnergyGPS Special Report that will be published in the next ... » read more

Over the past few weeks, the conversation around renewables has picked up in both the West and in SPP/ERCOT where the former is tied to the lack of output during the cold period in the Pacific Northwest and Santa Anna winds in California.  The latter continues to be around how much more capacity will be added by year's end and what will be in place come summer when the power demand across both regions is at its peak.  This type of conversation definitely puts the renewable component on top of the mountain in many cases but also at the bottom of the hill in others. Starting with the top of the mountain look no further than the recent output in Texas as there have been days when the wind generation took over the majority share of the supply needed to meet the power demand on the ... » read more

As we start to move into the heart of winter, I thought it would be worthwhile to step back and take a look at how the renewable profiles in ERCOT are shaking out in Q4.  As we have documented in other blogs, articles and monthly reports, ERCOT is the front-runner when it comes to wind penetration across North America.  On the solar front, nobody can compete with California's drastic increase but going from nothing to something is always a start.  With the forward natural gas curve catching a bit of a bid in the market the past couple of weeks, the focus moving forward will be on how much new capacity will get added over the course of the next 6-7 weeks as an end of the year rush could be in order. Figure 1 | ERCOT Monthly Wind Breakdown You can see in the top pane in the ... » read more

The Lower 48 natural gas production has recently moved to a new high of 95.4 BCF. That is up 6.6 BCF from last year with a good portion of the gains coming as a by product of the crude production stream in the Permian Basin. Because the infrastructure in the Permian is mainly dedicated to the crude industry, natural gas volumes are particularly sensitive to weather shocks. The most recent polar event underscores how vulnerable the basin is to freezing temperatures. Noting we are at the beginning of the heating season there are more cold events on the way which will ignite volatility for Texas gas markets.     Figure 1 | Lower 48 Production Volume In the past three weeks we have seen two distinct temperature events throughout the Midcontinent. Each had a negative effect on ... » read more

For some time now, we have been discussing the power demand profile within CAISO's footprint as the renewable mandate over the years has netted what we consider a double hump profile.  The double hump occurs since most of the new renewable capacity comes in the form of both behind the meter solar and utility-scaled facilities integrated into the grid's daily supply/demand balance. Figure 1 | CAISO Net Load Profile - Hourly Actuals and Forecast The red lines in the graph above represent the power demand tied to the consumers of power on an hourly basis while the bright blue at the bottom is the wind generation hitting the grid while the faded orange is what gets generated by the sun (solar).  The former is volatile on a daily basis while the latter represents the utility-scaled ... » read more

If you have been in the electricity sector for some time, there are several revolving concepts and topics that always seem to pop up for discussion and/or debate depending on the time of year or circumstances around a specific market.  One of those topics is the 'Capacity Market' within each ISO and RTO sector across all of North America. At the end of the day, this hot topic serves as a foundation to what most would consider reliability to the power grid.  As stated, each market acts a little differently depending on the governing body and policy makers tied to the specific electricity balancing authority.  The discussion have takend several turns over the years with PJM being the pioneer over the years.  While other ISO's have been formed since the inception of ... » read more
