Western US Wholesale Energy Market Set to Expand: What to Know This Week
What You Need to Know About Energy Prices This Week
The California Independent System Operator (CAISO) expects to expand its energy imbalance market (EIM) into more portions of the western United States and Canada over the next three years.
The market, created in 2014, allows for the trading of wholesale electricity at sub-hourly intervals between neighboring grid operators. Since its creation, the market has grown to include PacifiCorp, NV Energy, Puget Sound Energy, and the Arizona Public Service. Current plans will bring six more balancing authorities from the US into the fold by 2020, as well as Powerex, a subsidiary of the Canadian balancing authority BC Hydro.
The expanded market expects to lower costs by better matching supply and demand across territories. During supply shortages, rather than dispatching comparatively expensive local resources, members will be able to import excess power from others within the EIM. It also helps to alleviate some concerns of oversupply with intermittent resources like wind and solar.
A Brief Primer on Energy Markets
Every week, EnerNOC’s energy intelligence team analyzes the market developments driving energy prices. In this weekly article, you’ll see a lot of discussion about energy generation sources, such as natural gas, coal, nuclear, and some renewable and distributed energy resources. You’ll also see a lot of talk about the factors affecting generation: weather, production, storage levels, natural disasters, geopolitical events, and so on.
The connections between the drivers and the energy markets are complex, but here’s what you should know in a nutshell. Weather is a key driver because it has a direct impact on demand for electricity and natural gas. Temperature extremes cause spikes in demand for natural gas, either directly for home heat or indirectly as a fuel source to generate electricity for air conditioning. Similarly, unexpected natural disasters or geopolitical events could suddenly affect supply, which has a similar downstream effect on pricing. And, of course, any change in pricing is going to affect your organization’s energy costs. Keeping up with new developments in the market is important to ensuring you don’t miss opportunities that could save significant money for your business over the long term.
If this is all still a little confusing, talk to an energy procurement expert to learn why the factors affecting energy markets actually matter to your business.

How Are Natural Gas Prices Trending?
This chart shows how month-ahead prices for natural gas are settling on the New York Mercantile Exchange. It is a good indicator of where the market is, relative to where it has been over the past four years.
What Do Forward Natural Gas Markets Look Like?
Henry Hub represents a main distribution center for natural gas. Activity at the Henry Hub is considered a benchmark for natural gas prices in markets across the country, including the NYMEX and OTC Global Holdings. This chart shows how Henry Hub forward prices for natural gas have trended over the past calendar year.
1 Year Trend of Power Around-the-Clock Calendar Year Prices
Prices for power are constantly fluctuating, and it can be difficult to know exactly when they are going to spike or plummet. These charts show how future power prices have trended over the past calendar year for New England (ISO-NE), the mid-Atlantic region (PJM), New York City (NYISO Zone J), and Northern Illinois.
1 Year Trend of Natural Gas Calendar Year Prices
While the Henry Hub provides the benchmark, prices tend to vary based on regional factors. These charts show how forward prices are trending over the previous calendar year at the hubs for New England (Algonquin), New York (both Transco Z6 NonNY and Transco Z6 NY) and Chicago (Chicago City Gate).
Extreme swings in weather can significantly impact energy prices. These maps depict forecasts courtesy of the National Oceanic and Atmospheric Administration. Blue shading indicates areas with a high probability of seeing below-average temperatures, and red shading shows areas that are likely to see above-average (white areas are most likely to see average temperatures for their climate). The darker the shade of either color, the higher the probability that the corresponding area will see abnormal weather.
