Maine PUC stops tax on medium and Large Customers using their own solar power


On December 12, 2018, the Maine Public Utilities Commission (PUC) granted a petition from Insource Renewables to suspend so-called “gross metering” for medium and large electricity users, citing excessive costs to all ratepayers to implement the policy. Gross-metering was adopted by the PUC two years ago to replace net metering. It requires the installation of expensive extra metering equipment in order to charge solar customers a new tax or fee on the power they produce and consume right in their home or business.

“This is the beginning of the end for a failed policy that has thwarted Maine’s renewable energy sector, penalized Maine people and businesses that want to invest in energy independence, and needlessly burdened all ratepayers,” said Dylan Voorhees, Clean Energy Director for the Natural Resources Council of Maine. “While we are disappointed that the PUC did not also drop gross metering for Maine homes and small businesses, the evidence is in that this policy has got to go before more damage is done.”

Insource informed the PUC that the cost of additional metering equipment at medium and large businesses that go solar is reaching or exceeding $2,000 per business. These added costs are born by all utility ratepayers. In contrast, the revenue all ratepayers receive from collecting gross metering taxes from these businesses is now estimated at $50 per year.

“Congratulations to Insource Renewables and others for getting the PUC to reverse the costly gross metering tax on medium and large solar customers.  I have filed a bill to eliminate gross metering for ALL customers, and look forward to its speedy passage in January,” said Rep. Seth Berry, who has been a tireless advocate for clean energy in Maine.

NRCM, ReVision Energy, and many other parties supported Insource’s petition and argued that gross metering should be suspended for all customers, something that must now be done by the Legislature.

“Gross-metering clearly discourages customers from installing solar, and it is also bad news for those who want to reduce electricity costs in Maine,” said Voorhees. “Solar and consumer advocates warned the PUC and lawmakers that the policy would be costly and short-sited, including former Public Advocate Tim Schneider. Unfortunately, it has been even worse than predicted.”

Governor-elect Mills has vowed to fully repeal gross metering. Legislation to do so passed in 2017 and 2018 with strong bipartisan majorities, only to fall just short when attacked and vetoed by Governor LePage.

“We look forward to leaving behind this sorry chapter in Maine’s renewable energy history books,” said Voorhees. “Clean energy technology continues to advance and has become the cheapest way to meet our energy needs. It is time for Maine to embrace the opportunity to tap our abundant local renewable energy resources to create jobs, reduce pollution, and increase energy independence. Repealing gross metering will be a necessary reset, and then we have much more to do to move the state forward on solar power and renewable energy.”

 NRCM and allies including the Conservation Law Foundation, ReVision Energy, and the Industrial Energy Consumers Group have previously filed a lawsuit in Maine Superior Court challenging the PUC’s rule. That case has not proceeded to the argument phase, and may be superseded by legislative action next session.
