Local weather and clear power advocates in New Hampshire say a pending proposal to outline nuclear energy as clear power may undercut photo voltaic and wind energy within the state.
Though the main points are nonetheless within the works, state Rep. Michael Vose, chair of the legislature’s science, know-how and power committee, is drafting a invoice that may permit nuclear energy mills, corresponding to New Hampshire’s Seabrook Station, to obtain funds for contributing clear power to the grid.
“The broad concept is that, long-term, we are able to hope and anticipate that that dependable supply of baseload energy will at all times be there,” Vose mentioned. “It received’t be pushed out of enterprise by sponsored renewable energy.”
Some environmental advocates, nonetheless, fear that the proposal would offer pointless subsidies to nuclear energy whereas making it more durable for photo voltaic initiatives to draw buyers.
“It’s simply one other solution to cut back assist for photo voltaic,” mentioned Meredith Hatfield, affiliate director for coverage and authorities relations on the Nature Conservancy in New Hampshire.
Renewables and reliability
New Hampshire’s renewable portfolio normal — a binding requirement that specifies how a lot renewable energy utilities should buy — went into impact in 2008. To fulfill the requirement in that first 12 months, utilities had to purchase renewable power certificates representing 4 p.c of the entire megawatt-hours they equipped that 12 months. The quantity has steadily climbed, hitting 23.4 p.c this 12 months.
New Hampshire was the second-to-last state within the area to create a binding normal — Vermont switched from a voluntary normal to a mandated one till 2015. New Hampshire’s normal tops out at 25.2 p.c renewable power in 2025, however the different New England states vary from 35 p.c to 100% and look additional into the longer term.
Till we are able to have reasonably priced, scalable battery storage, the intermittency of renewables goes to ensure that renewables are unreliable.
Vose, nonetheless, worries that even New Hampshire’s comparatively modest targets may put the reliability of the facility provide in danger.
“Till we are able to have reasonably priced, scalable battery storage, the intermittency of renewables goes to ensure that renewables are unreliable,” Vose mentioned. “And if we add too many renewables to our grid, it makes the entire grid unreliable.”
That concept has been broadly debunked. Grid consultants say variable renewables might require completely different planning and system design however usually are not inherently much less dependable than fossil gasoline technology.
The small print of Vose’s clear power normal invoice haven’t but been finalized. A clear power normal is broadly completely different from a renewable power normal in that it consists of nuclear energy, which doesn’t emit carbon dioxide, however which makes use of a nonrenewable gasoline supply. These writing the laws, nonetheless, should resolve whether or not it is going to suggest incorporating the brand new normal into the prevailing renewable portfolio normal or working the 2 methods alongside one another.
Clear power advocates say they aren’t essentially against a clear power normal, however argue it’s essential that such a program not pit nuclear energy and renewable power in opposition to one another for a similar pool of cash. And they’re involved that that’s simply what Vose’s invoice will do.
“Whereas we might welcome a sturdy dialog about learn how to design a clear power normal, I concern that’s not what this invoice is,” mentioned Sam Evans-Brown, government director of nonprofit Clear Vitality New Hampshire.
Undermining renewables
If a clear power normal is structured so each nuclear and renewables qualify to satisfy the necessities, clear power certificates from nuclear energy mills would flood the market, inflicting the worth to plummet. Seabrook alone has a capability of greater than 1,250 megawatts, whereas the most important photo voltaic growth within the state has a capability of three.3 megawatts. Income from renewable power certificates is a vital a part of the monetary mannequin for a lot of renewable power initiatives, so falling costs would probably imply fewer photo voltaic developments may entice buyers or flip a revenue.
On the identical time, nuclear mills may promote certificates for low costs, as they have already got functioning monetary fashions that don’t embody this added income. Nuclear may, in impact, drive photo voltaic and different renewables out of the market virtually solely, clear power advocates fear.
Nuclear may, in impact, drive photo voltaic and different renewables out of the market virtually solely, clear power advocates fear.
“The intention of the [renewable portfolio standard] has at all times been about creating gasoline range by getting new technology constructed, and a proposal like that may do the other,” Evans-Brown mentioned.
A single normal that mixes nuclear and renewables may additionally harm growth of photo voltaic initiatives in one other approach, Hatfield mentioned. When New Hampshire utilities don’t buy sufficient renewable power credit to cowl the necessities, they have to make an alternate compliance fee. These funds are the one supply of cash for the state Renewable Vitality Fund, which supplies grants and rebates for residential photo voltaic installations and power effectivity initiatives.
“If you happen to add in nukes and due to this fact there’s plentiful cheap certificates, you then principally don’t have any various compliance funds,” Hatfield says. “It may doubtlessly dry up the one actual supply now we have within the state for clear power rebates.”
Though Vose and the invoice’s different authors haven’t but launched the main points of the proposal, he has indicated that he wouldn’t like the brand new clear power normal to considerably improve prices for New Hampshire’s ratepayers. The prevailing normal value ratepayers $58 million in 2022, when utilities have been required to purchase certificates masking 15 p.c of the facility they equipped, in keeping with a state report issued final month.
The laws might meet the identical destiny as final 12 months’s effort, Vose acknowledged, however he’s nonetheless wanting to get folks speaking in regards to the subject.
“Even when we are able to’t get such a typical handed on this session,” he mentioned, “we are able to at the least start a severe dialogue about what a clear power normal would possibly appear like.”
