So … that was fast. US natural gas stakeholders barely had time to congratulate themselves for pushing coal out of the power generation market, and it looks like karma is already getting the last laugh. Low-cost renewable energy is beginning to nudge natural gas aside. In the most recent and striking development, California’s massive 262-megawatt Puente gas power plant proposal has been shelved, perhaps permanently.
Electricity Consumers Push Back On Natural Gas
Reporter Ivan Penn of the LA Times has the scoop on the Puente project, and he teases out several powerful forces at work against natural gas.
One key element is consumer pushback. At first glance, the proposal doesn’t seem overly controversial. The proposed plan, a project of NRG Energy, does not involve constructing a new facility. It would have replaced two existing gas units at the company’s existing Mandalay power generation facility in Oxnard, California.
All things being equal, the proposal would provide at least some degree of environmental benefit, because the new units would use 80% less water for cooling than the existing ones.
However, criticism of the new gas project was intense. Penn sums it up: earlier this month, a two-member review committee of the California Energy Commission took the rare step of issuing a statement recommending that the full Commission reject the plans after receiving “hundreds of messages protesting the project as another potential pollution threat to a community already overwhelmed by electricity-generating plants.”
The Rates Are Too Damn High
Aside from concerns about local air quality, Penn also cites an LA Times investigation indicating that the state’s energy policy has over-estimated the demand for natural gas power plants, resulting in artificially high rates:
“The commissioners’ recommendation followed Los Angeles Times investigations that showed the state has overbuilt the electricity system, primarily with natural gas plants, and has so much clean energy that it has to shut down some plants while paying other states to take the power California can’t use. The overbuilding has added billions of dollars to ratepayers’ bills in recent years.”
According to Penn, NRG officials maintain that older plant retirements by 2021 make replacement imperative to build up now.
At current costs, local ratepayers won’t get much relief if old power units are replaced with wind or solar.
My Beach, My Choice
Land use issues and environmental justice issues also come into play. NRG’s Mandalay power generation facility is located on the beach, and as NRG acknowledges, in 2014 the City of Oxnard enacted a moratorium on coastal development.
That complicates development plans within the power plant site, though NRG emphasizes that the final decision rests with state-level regulators.
Among those objecting to the plant from outside the local community is billionaire investor Tom Steyer, who co-authored an op-ed about the proposed facility raising the environmental justice issue:
“…in our state, not all beaches are created equal. That becomes painfully clear if you drive 50 miles north of Los Angeles to Oxnard, where the beaches have been seized by corporate polluters, marred by industrial waste and devastated by three fossil-fuel power plants that sit along the shoreline.
“Oxnard has more coastal power plants than any other city in the state, and not coincidentally, its population is predominantly Latino and low-income….”
“Many residents of this predominantly Latino city with a population of 205,000 say they are fed up with the degradation. Their growing dissatisfaction with the condition of large sections of beach has coalesced into an effort to deindustrialize and restore the shoreline of this city that is framed by Ventura and Camarillo and wraps around the town of Port Hueneme.”
So, What’s The Solution?
The Puente project has been suspended, not canceled. However, chances of revival are slim. Although the most recent study affirms that renewable energy is a more expensive choice currently, Steyer points out that the redevelopment of Oxnard’s beachfront could be balanced out by new economic activity related to tourism and recreation.
That opens up a whole ‘nother can of worms, as waterfront development typically drives up the cost of housing, squeezing former residents to outer rims with longer commutes and fewer resources.
Sticking to the energy cost issue, the basic problem comes down to local energy vs. long distance transmission.
NRG makes the case that local energy generation is more reliable. That’s a fair assessment as a general principle, as the old model of centralized power plants falls out of favor. Local and on-site generation is becoming a consensus argument among energy experts, regardless of the power source.
On the other hand, the risk involved in transmitting electricity from remote wind farms and solar power plants could be offset by local storage sites, where the growing microgrid movement would come into play.
New tools for financing energy efficiency improvements could also help tamp down local energy demand and ease the way for a more interactive grid that enables consumers to tweak their electricity consumption to help prevent outages.
Cities like Oxnard can also tap into a growing renewable energy knowledge base that leverages local opportunities for renewable energy development and energy efficiency improvements.
Most of all, the Trump administration’s willy-nilly approach to oil and gas development — for example, a new proposal involving drilling along the Pacific coast — raises the stakes for citizens far outside of the communities dealing with local land use issues, leading to a groundswell of support for alternatives.
