What Happened to Pulse Power?
Pulse Power launched around 2020 as a budget provider under Shell/MP2 Energy. They competed purely on rock-bottom rates with no green options, no rewards, and minimal service infrastructure.
Pulse Power has stopped accepting new enrollments. Existing customers continue to receive service through their contracts, but the provider is effectively winding down.
Why Green Mountain Energy Is Still Here
Green Mountain Energy was America’s first company dedicated exclusively to cleaner energy. Founded in 1997, now owned by NRG Energy. They have operated in Texas for 29 years.
What Green Mountain Energy offers:
- 100% renewable electricity plans (wind and solar sourced)
- Solar buyback plans for rooftop solar customers
- Fixed-rate and variable plan options
- 29 years of clean energy track record
- NRG Energy backing — Fortune 500 financial stability
- Service across all major Texas TDU areas
Green Mountain charges premium rates — typically 15-25% above budget providers. That premium goes toward genuine renewable energy sourcing.
If You Are a Current Pulse Power Customer
Your service continues through your current contract. When it ends, you will need to switch.
If you valued Pulse Power’s budget rates, Green Mountain costs significantly more. For budget providers with corporate backing, check Discount Power (NRG — same parent as Green Mountain), Frontier Utilities (NextEra), or 4Change Energy (Vistra).
If you are ready to prioritize renewable energy, Green Mountain is the most proven green option in Texas.
The Verdict
Choose Green Mountain Energy if 100% renewable electricity from America’s oldest green energy company is worth paying a premium — backed by NRG’s Fortune 500 stability.
