What Happened to Pulse Power?
Pulse Power launched around 2020 as a budget provider competing on rock-bottom rates. They were operated under Shell/MP2 Energy. The company has since stopped accepting new enrollments. Existing customers continue to receive service through their current contracts, but no new sign-ups are available.
Pulse Power’s exit from active enrollment demonstrates the risk of small, independent-style providers. Companies competing purely on lowest price often lack the margins to sustain operations long-term.
Why Constellation Is Still Here
Constellation Energy [NASDAQ: CEG] is America’s largest carbon-free electricity producer with a $70B+ market cap. They own and operate nuclear reactors, wind farms, and solar installations across the country.
What Constellation offers:
- Genuine green energy from plants they own (nuclear, wind, solar)
- Fixed-rate plans (12-36 months)
- 15 years of Texas residential operations
- $70B+ market cap — unquestionable financial stability
Constellation charges premium rates — typically 20-35% above what budget providers like Pulse Power offered. The premium funds real clean energy infrastructure, not just wholesale electricity resale.
If You Are a Current Pulse Power Customer
Your service continues through your current contract. Shell/MP2 Energy is honoring existing agreements. When your contract ends, you will need to switch to another provider.
If you valued Pulse Power’s budget rates, Constellation is a premium option that costs significantly more. For budget providers with corporate backing, consider Discount Power (NRG), Frontier Utilities (NextEra), or 4Change Energy (Vistra).
The Verdict
Choose Constellation if you want genuine carbon-free electricity from America’s largest clean energy producer, with $70B+ in corporate stability.
