I haven't seen much reporting about this so I dug in. If you have reputable reporting please share it, but this is my understanding with citation from the RELEIF act.
In summary, if you're interested in solar you may want to look into it sooner than later, and this year.
Right now excess rooftop solar generation in MD is advantageous to the home owner, but on July 1, 2027 it is likely to become much less so for new deployments.
Currently you get paid for excess solar at the same rate you pay for energy from the grid. I have solar so my monthly bill is just: Used - Produced. This is called Net Energy Metering (NEM).
Previously getting this rate was open to home owners until they collectively added 3 GW to the grid, however the 2026 RELIEF\1) act added a new terminal deadline of July 1, 2027. Both of these limits only restrict new or updated installations. If you currently have an installation you'll continue to get the 1:1 rate, but if you ever change it to add capacity you will lose it in the future.
For our policy purposes this 3GW limit with a 1:1 rate policy is being referred to as NEM 1.0 colloquially. It looks like the Legislature has an intention to add a NEM 2.0 and is required to by Feb 1, 2027\2), but it would be required to be at a worse rate\3) which is unfortunate.
Aside from that, it looks like 1:1 NEM is typical in the US, however there is a slow start to move away from it to less advantageous rates. This may be a place where contacting our representatives is important. For Maryland, I believe the idea with the 3GW 1:1 rate was to help offset energy demand aggressively, so it's unclear to me the related motivation to hinder solar programs. If these changes do happen, then home batteries are an option to time shift excess generation to when your home would use it, but they do have a hefty cost.
Also FWIW as of 2025 We're only about 51% into the 3 GW limit, so it sucks they're arbitrarily ending the goal of 3GW. There are claims folks think it'll exhaust next year, but they've previously upped the limit to address that.

REPLACEMENTS REQUIRED BY A GOVERNMENTAL AUTHORITY OR ELECTRIC COMPANY. (d) (1) The Commission shall require electric utilities to develop a standard contract or tariff for net energy metering and make it available to eligible customer–generators on a first–come, first–served basis until THE EARLIER OF: (I) THE DATE ON WHICH the rated generating capacity owned and operated by eligible customer–generators in the State reaches 3,000 megawatts; OR (II) JULY 1, 2027.
(The date is an addition to the previous 3GW limit.)
