- ▸HB 1532 signed May 12, 2026 with an emergency clause — effective immediately, no waiting period
- ▸1,200W cap, with a lower 391W sub-threshold called out in the broader regulatory template
- ▸No fully UL 3700-certified system is confirmed available yet

Key Takeaways
- ✓Maryland HB 1532 took effect immediately on signing, May 12, 2026 — no waiting period, unlike most other states.
- ✓The 1,200W cap matches the majority template; a separate 391W sub-threshold is also referenced in the regulatory framework.
- ✓Maryland's DC-adjacent location means many residents pay DC-area electricity rates, relevant context even though a Maryland-specific savings figure isn't independently confirmed here.
- ✓No complete system has confirmed full UL 3700 certification yet, same as every other enacted state.
What Does HB 1532 Require in Maryland?
**Maryland's HB 1532, the Utility RELIEF Act, is the fastest-moving of the 8 enacted state laws — it carried an emergency clause, meaning it took effect immediately on signing rather than after a standard waiting period.** The standard cap is 1,200W, matching the majority template used across most enacted states. A separate 391W sub-threshold also appears in the broader multi-state regulatory framework, which may apply lighter-touch treatment to smaller devices — confirm the exact mechanics against Maryland's statutory text before relying on the distinction for a specific device.
Like other enacted states, net metering does not apply — excess power exported to the grid earns no compensation, and the exact cap figures here were not independently re-verified against primary Maryland Public Service Commission text this pass.
| Field | Maryland HB 1532 |
|---|---|
| Signed / Effective | May 12, 2026 / Immediate (emergency clause) |
| Wattage cap | 1,200W (391W sub-threshold referenced) |
| Net metering | Not available |
Are Certified Kits Actually Available Yet?
**Maryland's law, like every other enacted state's, references UL 3700 as the safety benchmark, but no complete plug-in solar system has confirmed full certification as of write-time.** The standard was published December 2025 with testing opening January 2026 — a gap that applies nationally. EcoFlow's STREAM Ultra is the closest product to market but is currently listed for sale specifically in Utah, not Maryland.
Maryland wasn't in the source tracker's state-by-state savings table used for this series, so a Maryland-specific dollar figure isn't available here. Across the states that were tracked, an 800W kit saves roughly $150–$350 per year depending on local electricity rates — Maryland's DC-adjacent electricity rates likely put it toward the higher end of that range, but treat this as a national range, not a confirmed Maryland estimate.
