Last month, Xcel Energy subsidiary Public Service Company of Colorado (PSCo) filed a rate case at the Colorado Public Utilities Commission (Docket: 14AL-0660E). A lot of the case — the part that’s gotten most of the press — is about PSCo recovering the costs of retiring and retrofitting coal plants as agreed to under the Clean Air Clean Jobs Act (CACJA) of 2010. However, there’s a piece of the case that could have much wider implications. Way down deep in the last piece of direct testimony, PSCo witness Scott B. Brockett:
…provides support and recommendations regarding the initiation of a decoupling mechanism for residential and small commercial customers.
This recommendation has captivated all of us here at CEA because it could open the door to Xcel adopting a radically different business model, and becoming much more of an energy services utility (PDF), fit for the 21st century.
To explain why, we’re going to have to delve a ways into the weeds of the energy wonkosphere.

On April 9, the Commissioners of the Colorado PUC held a three hour informational meeting with presentations from Xcel, the collective solar parties, the Colorado Energy Office, the Office of Consumer Council, and Western Resources Advocates. The outlines of the process will start to firm up in May, but the parties laid out some general ideas for process and substance in PowerPoint presentations before a packed house.
As a quick recap, remember that this matter spun off from the 2014 RES compliance docket at the motion of the Colorado Energy Office. Their argument was, essentially, that if the value of solar was going to be debated it should get its own hearing instead of being stuck in the compliance plan almost as a sideshow. The CEO argued that severing the issues would “increase transparency and allow stakeholders from across the state to participate in the dialog related to incremental costs, net metering incentives, and solar energy rates.” (CEO motion 21 Jan 2014) The commissioners deliberated on the motion at their weekly meeting on January 29 and granted that motion shortly thereafter with much hand wringing about the structure of the new proceeding.
In response to that hand wringing, the commissioners held this informational meeting with the parties directed to discuss their “recommendations on the substantive issues the Commission should address in this proceeding, objectives the Commission should meet, and the best procedures satisfying those objectives.” (Decision No. C14-0294 in proceeding 14M-0235E) Continue reading Colorado PUC takes the next bite at Net Metering
This case was originally filed June 17, 2013 and is a strategic demand side management issues matter. Demand Side Management (“DSM”) refers generally to policies that aim to reduce energy consumption overall (through energy efficiency and other programs) and moving certain loads from peak to off peak periods.
Value of Demand Side Management
Although taking the same consumption and moving it to a different time might not seem like it will make a huge difference in energy use and consumption, it’s a very important resource. Certain generating units called “peaking plants” (or “peakers” burning methane) operate only when there is a larger than usual demand for energy, such as a really hot day when everybody is running their air conditioners at the same time. In those instances, the peaking plant kicks on and saves the day. Peaking plants are more expensive to operate and are typically much less efficient than fossil baseload resources (if those resources are operating properly, but that’s another chapter). If there’s a large manufacturing plant that can temporarily suspend their operations or reduce their consumption in other ways to a large enough degree, Xcel won’t have to turn that peaker on at all. Peaking plants generally operate about 100 hours or less per year. By moving a large load from the middle of the day to the middle of the night when loads are lighter, we’re still using the same amount of energy, but it won’t come from that inefficient peaking plant. Energy efficiency and demand response are great programs that change the picture of energy consumption and can make a huge difference in reducing emissions stemming from fossil generation.
Xcel’s DSM program is in response to legislation passed in 2007. The Legislature declared in HB 07-1037 that “cost-effective natural gas and electricity demand-side management programs will save money for consumers and utilities and protect Colorado’s environment.” Through this legislation the PUC was “encouraged” to “reduce emissions or air pollutants and to increase energy efficiency.” The goal is for electric utilities to reduce peak generation by 5% from the 2006 levels by 2018. The bill allowed for utilities to recoup their investments in DSM programs at a higher rate of return than other generation investments.
