They should have had one of their students do the math...
Estimated savings of 6,500 gallons of diesel per day x $4/gal (probably cheaper than $4 since they should be able to buy at wholesale prices and maybe without taxes). That's $26,000 saved per day x 180 school days per year, or about $4.68 million saved per year. They spent about $170 Million for these buses. They breakeven in about 36 years, assuming the buses last that long without any additional cost (yeah, right!) I wouldn't take that investment!

And they never add in the extra cost for electricity to charge them all. //

So the "green" yellow school busses are putting the school/county/city budgets in the red?

PJM’s capacity auction has competitively secured resources to meet the RTO reliability requirement for the 2025/2026 Delivery Year. Auction prices were significantly higher across the RTO due to decreased electricity supply caused primarily by a large number of generator retirements, combined with increased electricity demand and implementation of FERC-approved market reforms.

While the overall resource mix is adequate, two zones cleared just short of their reserve requirement, resulting in prices being set at the zonal cap.

The higher prices send a clear investment signal across PJM’s 13 states and the District of Columbia. //

The auction cleared a diverse mix of resources, including 48% of gas, 21% of nuclear, 18% of coal, 1% of solar, 1% of wind, 4% of hydro, 5% of demand response and 2% from other resources. //

The amount of supply resources in the auction decreased again this year, continuing the trend from recent auctions and underlining PJM’s stated concerns (PDF) about generation resources facing pressure to retire without replacement capacity being built quickly enough to replace them. Approximately 6,600 MW of generation have retired or have must-offer exceptions (signaling intent to retire) compared with the generators that offered in the 2024/2025 Base Residual Auction (BRA).

Meanwhile, the peak load forecast for the 2025/2026 Delivery Year has increased from 150,640 MW for the 2024/2025 BRA to 153,883 MW for the 2025/2026 Delivery Year. Additionally, FERC-approved market reforms contributed to tightening the supply and demand balance by better estimating the impact of extreme weather on load and more accurately determining resource reliability value.

These reliability concerns associated with reducing supply and increasing demand are not limited to PJM; the North American Electric Reliability Corporation has identified elevated risk to the reliability of the electrical grid for much of the country outside of PJM. To facilitate the entry of new resources, PJM is implementing its FERC-approved generation interconnection reform, with approximately 72,000 MW of resources expected to be processed in 2024 and 2025. //

The auction produced a price of $269.92/MW-day for much of the PJM footprint, compared to $28.92/MW-day for the 2024/2025 auction. Capacity auction prices fluctuate annually based on the need for investment in generation resources.

This year’s auction procured 135,684 MW for the period of June 1, 2025, through May 31, 2026. The total Fixed Resource Requirement (FRR) obligation is an additional 10,886 MW for a total of 146,570 MW.

The total procured capacity in the auction and resource commitments under FRR represents an 18.5% reserve margin, compared to a 20.4% reserve margin for the 2024/2025 Delivery Year.

Sorry, but that just won't wash in terms of facts. "Alcohol" drag engines actually run on methanol with a significant percentage of "additives" to increase the volatility, thus, energy release. In the parlance it is known as "moon juice".
Auto fuel is ethanol and an "extender" of petroleum based gasoline with some noticeable deficiencies - primary among those being corrosivity to metal engines and parts. Ethanol is a boondoggle of epic proportions. So called "bio-diesel" is similar in terms of effective fuels for actual usage. Both are a kind of an equivalent to Kwanza - a government invention without merit, foundation, or actual substance. Both are great ways to obfuscate useless and expensive government initiatives with unduly loud claims and unicorn flatulence.
