Is DTE’s meter plug worth it? Year-one and 3-year math

The short answer

over 3 years, the meter plug costs about $930–$1,080 in DTE fees. An electrician-installed interlock is about $400–$850 one time (HomeGuide). A standby is $6,000–$20,000 installed, most whole-house installs $10,000–$15,000 (HomeGuide, Generac). The plug wins on ease; the interlock can win on cost if you stay put.

Interlock, installed (electrician)$400–$850$400–$850

DTE math: install fee + $22.99 × 12 or × 36 months (DTE). Transfer switch: DTE’s FAQ says “typically $1,500” and 2–3 hours (DTE FAQ). Interlock and standby ranges: HomeGuide and Generac. Standby service: about $171–$396 per visit (Angi). Our arithmetic; get quotes for your house.

Add the generator

Portable generators typically cost $500–$2,500 (HomeGuide). So year one with DTE’s plug is roughly $900–$3,000, against $6,000+ for a standby.

When the meter plug is worth it

  • You want it done fast, with no electrician and no permit.
  • Your must-haves fit under 7,200 or 9,600 running watts.
  • You like the surge coverage that comes with it.

When it isn’t

  • You’ll keep the house 5+ years and an electrician quotes a low price for an interlock: no monthly fee.
  • You have electric heat, a well and sump, medical needs in long outages, or you’re often away. Then a standby is the better fit.
  • Your service is over 200 amps (DTE requires 200 or less).

About $927.63 (30-amp) or $1,077.63 (40-amp): the install fee plus 36 months at $22.99.

Is a standby generator worth it instead?

For heavy loads, electric heat, well plus sump, medical needs or homes often left empty, often yes. Installed cost runs $6,000–$20,000, most whole-house installs $10,000–$15,000 (HomeGuide, Generac).

Two rules that save lives

Never run a generator in a garage, porch or near a window. Keep it 20 feet out, exhaust away.

Never backfeed through a dryer outlet. Use the meter hookup, an inlet or a transfer switch.
