Renewables yes, but at what a cost?

By Cynthia Mitchell | My View | The Santa Fe New Mexican |

Much has been made about the benefits of the proposed Avangrid-Public Service Company of New Mexico merger. However, the costs to ratepayers are substantial.

If the merger (i.e. acquisition), is approved, PNM will be a subsidiary, not partner, to Avangrid. It would be difficult, if not impossible, to police the holding companies of Avangrid and its Spain parent company, Iberdrola; the Avangrid/Iberdrola affiliates, business spinoffs, would remain most significantly outside of the regulation of the Public Regulation Commission. As Avangrid develops solar generation in New Mexico, Avangrid, not PNM, would own the generation. PNM would buy Avangrid’s solar through purchase power contracts and recover the costs on a dollar-for-dollar basis in utility rates. Avangrid, not PNM, would reap all the profits on the solar generation. PNM, as a subsidiary to Avangrid, would be at the mercy of Avangrid’s potentially very pricey solar.

Similarly, during the PRC merger hearings, Avangrid testified that it intended to use New Mexico as its “beachhead” for solar generation for the out-of-state wholesale market. This means all the profits would flow to Avangrid and Iberdrola. Thus, the state of New Mexico would lose a key source of potential revenue for its much-needed economic diversification from oil and gas.

It’s important to know that Avangrid’s renewable energy portfolio is almost all wind generation, with less than 2 percent solar. Also during the PRC merger hearings, Avangrid stated it would be starting toward the bottom of a learning curve in developing New Mexico solar.

And understand that in its 2020 integrated resource plan (that did not include the merger), PNM touts it will be 100 percent emissions-free by 2040. Further, PNM is getting out of coal – Four Corners and San Juan – without the merger. With San Juan, PNM is replacing the coal electricity with solar. While Avangrid claims it will have PNM emissions-free by 2035, that date could certainly slip given Avangrid’s steep solar learning curve. (See and

The way forward to 100 percent clean energy and a new significant source of state revenues beyond oil and gas royalties is not through acquisition of PNM by private, for-profit holding companies, but through a public partnership with the state of New Mexico where all citizens – most certainly the Indigenous communities most impacted by coal generation and oil and gas fracking – are the “shareholders” benefiting from not only a cleaner environment and better health, but the profits from a sustainable economy.
