TL;DR

Electric aviation isn't a 2040 story anymore. Beta Technologies' CX300 is in FAA certification with a 2026 commercial entry target. Joby and Archer expect to fly paying eVTOL passengers in NYC and LA in 2026. Heart Aerospace's hybrid-electric ES-30 has more than 250 firm orders from major airlines. Eviation's all-electric Alice has been in flight test since 2022.

The bottleneck isn't aircraft technology — it's ground-side power. An electric airliner needs 1-4 megawatts of charging to be operationally viable, which is 4-12× what today's most powerful DCFC stations can deliver. The CharIN Megawatt Charging System (MCS) standard, originally designed for Class 8 electric trucks, is the same plug that's about to power electric airliners.

Here's what's flying, what's coming, and why the megawatt charger matters for both.

What changed: hybrid-electric is the realistic near-term

Three years ago the conversation was "can we ever build a fully electric 737?" The honest answer is no — not at any timeline a current investor would care about. Battery energy density is improving 5-7% per year, and even at that pace, all-electric narrowbody jets aren't economically viable until the 2040s.

The shift in 2024-2025 has been to hybrid-electric for regional aircraft. Heart Aerospace's ES-30 is the canonical example: 30 seats, 200 km of all-electric range for the daily-flown short hops, plus a generator that gives 400 km of hybrid range when needed. United Airlines, Air Canada, Mesa, and SAS combined have ordered hundreds of them. The economics work because most regional turboprop routes are sub-200 km and operate at 3,000-foot fuel-burn-pessimistic altitudes — exactly where electric is most efficient.

The other shift is eVTOL (electric vertical takeoff and landing) for urban air mobility. Joby, Archer, Wisk, and Vertical Aerospace are all building 4-5 seat aircraft for short city-to-city or airport-shuttle hops. Joby's S4 is the closest to commercial service — Delta is the launch partner, NYC and LA are the launch markets, and target entry is 2026.

The routes electric aviation actually opens

The pitch for electric aviation isn't "replace 737s." It's that there are point-to-point routes that don't justify a regional jet — flights of 100-300 km between cities that aren't on the major hub network. Driving those routes takes 3-5 hours; a 30-seat electric aircraft can do them in 30-60 minutes at a cost-per-seat-mile competitive with driving.

A few real examples:

  • Detroit ↔ Cleveland (160 km direct). Currently 3 hours by car or a multi-hop flight via DTW or CLE. Heart ES-30 covers it all-electric, no fuel.
  • Boston ↔ Portland, ME (170 km). Currently 2.5 hours by car. ES-30 territory.
  • San Francisco ↔ Reno (300 km). The mountains make it a 4-hour drive. ES-30 hybrid mode handles this; Beta CX300 in pure electric.
  • Miami ↔ Key West (260 km). The Overseas Highway is one of the most beautiful drives in America, but 3.5 hours one-way. CX300 can do it in 90 minutes.

These aren't hypothetical. Mesa Airlines (a regional operator) ordered 200 ES-30s explicitly to fly routes like these — short, direct, point-to-point connections that don't justify a CRJ-700 today because the economics break at 50+ passengers but make sense at 30.

The megawatt charger problem

Here's where the ground side gets interesting. An ES-30 has roughly a 1 MWh battery pack. To recharge it in the 30-minute turn time airlines demand, you need 2 MW of continuous charging power. A Joby S4 has roughly a 200 kWh pack but needs 10-minute turns for high-frequency operations — so 1 MW or more.

For comparison: today's fastest DCFC stations top out at 350 kW. The Tesla V4 Supercharger architecture targets 500 kW. Neither is even close to what an electric aircraft needs.

The Megawatt Charging System (MCS) is the answer. CharIN — the same consortium that runs the CCS car-charging standard — finalized the MCS spec in 2022 and the SAE J3271 ground-vehicle standard followed. The current peak is 1.25 MW at 1,250 V and 3,000 A continuous; the standard is designed to scale to 4 MW for future use cases.

MCS has a different physical connector than CCS or NACS — the cable is liquid-cooled and the contacts are sized for 3,000 amps continuous. It is decidedly not something you'd plug into a car. But the standard itself is sector-agnostic: it powers Class 8 electric trucks today (Daimler eCascadia, Volvo VNR Electric, Tesla Semi) and will power electric airliners + eVTOLs from 2026.

Lilium and ABB demonstrated a working MegaWatt eVTOL charging system targeting 0-100% in 30 minutes / 0-80% in 15 minutes. Beta Technologies operates "BETA Charge" — an MCS-compatible network at general-aviation airports that's already serving the CX300 flight-test program.

What's at risk

Aviation electrification is moving fast but not without casualties. Two of the highest-profile programs hit serious trouble in late 2024 / early 2025:

  • Lilium filed for insolvency in October 2024. The German eVTOL company had been bleeding cash for years and ran out of runway when European public-market investors lost patience. They restructured under new investors in Q1 2025; the certification timeline is now uncertain.
  • Eviation laid off most of its staff in February 2025 after a cofounder dispute with the majority owner. The Alice program — which made history with the first all-electric regional aircraft test flight in September 2022 — is in a holding pattern. Cape Air's 75-aircraft order is in question.
  • Volocopter filed for insolvency in December 2024. They demoed at the 2024 Paris Olympics; restructured in 2025; commercial certification still pending.

The pattern: programs that promised commercial service in 2024-2025 have largely slipped or failed. Programs targeting 2026-2028 commercial entry (Joby, Archer, Beta, Heart) are in better shape because they raised more capital and set more realistic timelines.

What this means for charging operators

If you're building a charging business, MCS infrastructure is the next category. The planning question isn't "should we install MCS" — it's "where" and "when."

The early MCS deployments are at:

  1. Trucking corridors (the dominant use today). I-5 in California, I-80 across Nevada/Wyoming, I-40 across Texas/New Mexico. Daimler, Volvo, and Mack are all delivering Class 8 EVs that need MCS to be useful.
  2. General aviation airports with existing 480V three-phase service. Beta Charge is leading here — KBED, KCNK, KMKE all have Beta Charge MCS hardware live.
  3. Vertiports for eVTOLs. These are emerging now in NYC, LA, and Miami. Most are airline-operator-owned (Joby + Delta, Archer + United, Volocopter + Saudia).

For a charger investment business, the relevant numbers are:

  • MCS hardware cost today: $400k-$800k per dispenser (vs. $40k-$80k for a 150 kW DCFC).
  • Site service requirements: 480V three-phase at 5+ MW. Most existing commercial sites would need a substation upgrade.
  • Utilization economics: very different from passenger DCFC. Trucks and aircraft are scheduled, so utilization is high but predictable. The economics resemble fleet charging, not pay-at-the-pump retail.

For modeling that math, our Charger Investment Calculator handles the simplified single-charger case — passenger DCFC + L2 are the supported v1 scenarios. The MCS / fleet variant is on the roadmap; for rigorous analysis use Argonne's CHECT tool.

What to watch

Three things over the next 18 months:

  1. Joby S4 commercial entry in NYC. Targeted for late 2026. If it lands on schedule with a 2026 ride-paying passenger, the eVTOL category proves out. If it slips to 2028+, expect a wave of consolidation among the 7 active eVTOL companies.
  2. Beta CX300 certification. The first new fixed-wing aircraft type-certified in the US in over a decade (Cessna 408 SkyCourier was 2022). Type-cert timelines historically slip 12-24 months from initial guidance.
  3. MCS network density at GA airports. If Beta Charge + competitors get to 30+ live MCS sites by end of 2026, regional electric aircraft become operationally viable in real markets. If it stays at <15, the routes Heart Aerospace promises won't have ground infrastructure.

TL;DR

Electric aviation is real, near, and constrained mainly by ground-side power infrastructure. The megawatt-charging standard that solves it (MCS) is the same one already serving Class 8 trucks today. Watch Joby for proof-of-concept on the eVTOL side; watch Beta for proof-of-concept on the regional fixed-wing side; watch the MCS deployment count at GA airports for the binding constraint.
