Re-Assessing Renewable Portfolio Standards Critical To Address Energy Affordability Challenges
The renewable energy revolution has had a significant impact on the environment, but its effects on electricity bills have been less than stellar. A closer examination of state policies reveals that they are driving up costs and stifling competition in the electricity market.
In Washington, D.C., Mayor Muriel Bowser has highlighted the district’s high solar renewable energy credits, which cost $410.72 per megawatt-hour. This translates to an additional $20 on each electric bill, with the potential to double by 2029 and price out low-income households and small businesses.
State renewable portfolio standards (RPS) require electricity suppliers to purchase renewable energy credits (RECs), supposedly promoting clean energy. However, this system creates artificial scarcity by limiting where utilities can buy RECs, effectively turning the free market into a closed shop.
Pennsylvania’s Act 114 is a prime example of this phenomenon. By restricting Tier II alternative energy credits to in-state facilities only, the state has created a tariff barrier that drives up costs for consumers. The average Tier II credit price skyrocketed from $1.92 in 2020 to $26.92 in 2025 – a fourteenfold increase. Compliance spending rose from $3.6 million to over $367 million during this period.
Some argue that higher credit prices are necessary to encourage new in-state generation. However, data from the Pennsylvania Public Utility Commission (PUC) shows that renewable energy’s share of the state’s electricity mix remained stuck at 4% between 2013 and 2024, despite the compliance requirement rising to 18%. It appears these policies prioritize lining the pockets of in-state generators over driving real progress towards sustainability.
The RGGI market price for carbon reduction is a paltry $27.55 per metric ton – yet some states are paying as much as $840 per metric ton for solar credits. Any climate program that pays 30 times its neighboring market’s price should be subject to closer scrutiny, especially when it comes to cost transparency.
Federal regulators like FERC Chair Laura Swett have started to take notice of this problem. In a recent Senate testimony, she criticized states that use ratepayers as “piggy banks” for subsidizing programs with little to do with energy. It’s time for state policymakers to listen up and address these protectionist policies.
To rectify the situation, states should open their markets to allow suppliers to buy credits across the regional grid – increasing competition and transparency while lowering costs for consumers. RPS and solar carve-out expenses should also appear as separate line items on customers’ bills, not buried in bundled generation charges. Finally, states must review how effective their renewable energy mandates are – programs that only serve to change the price of existing generation should be redesigned or removed.
The affordability crisis in the electricity market is a ticking time bomb for environmental and energy policies alike. As long as state policymakers prioritize artificial scarcity and hidden charges over genuine competition and transparency, they’ll only have themselves to blame when public support for these programs dries up. The writing’s on the wall – it’s time to rethink the RPS system before it’s too late.

While RPS policies are well-intentioned, their design often prioritizes state-level economies over broader market efficiency. A crucial consideration is how these policies interact with existing grid infrastructure and energy storage capabilities. As the renewable energy share increases, so does the complexity of integrating variable power sources into the grid. Without addressing this challenge through complementary investments in smart grid technologies or demand management systems, states risk exacerbating energy affordability issues rather than alleviating them.

The renewable portfolio standards debate has reached a boiling point. While well-intentioned, these policies have created unintended consequences that undermine their original purpose. A crucial aspect often overlooked is the impact on energy storage and grid resilience. As RPS programs continue to drive up costs, consumers are left shouldering the burden of an increasingly unreliable grid. Policymakers would do well to re-examine the long-term implications of these policies and consider more equitable solutions that balance affordability with sustainability goals.

The renewable energy revolution has become a gravy train for in-state generators at the expense of consumers and genuine competition. By limiting where utilities can buy renewable energy credits (RECs), state policies are essentially creating artificial scarcity and driving up costs. The data suggests that this approach is not effective in increasing in-state generation, but it's clear: those who benefit most from these policies are not the environment or low-income households, but rather a select group of power brokers.
