The Short Answer
There’s no middle ground here.
Green Mountain: Pay $300-$500/year extra for 27 years of authentic renewable energy sourcing from Texas wind farms and solar generators. Every plan is 100% green. No exceptions.
Discount Power: Pay as little as possible. Zero green options. Zero marketing budget. Zero frills. They don’t even pretend to care about the environment.
Pick based on your values. These companies couldn’t be more different.
Overview
Green Mountain Energy pioneered renewable electricity in Texas starting in 1997. They contract directly with wind farms and solar installations. NRG Energy (NYSE: NRG) owns them now, but the renewable mission continues. You’re paying a premium for genuine environmental investment.
Discount Power is the opposite philosophy: spend nothing on marketing, nothing on apps, nothing on green energy, and pass every possible savings to customers. US Retailers LLC (also owns Cirro, Pennywise Power, and others) runs them. Five brands, zero environmental credentials.
The Price Gap
This is the biggest price difference of any comparison on this site.
Average Texas household: 1,200 kWh/month
Green Mountain rate: 12-14 cents/kWh (typically) Discount Power rate: 8-10 cents/kWh (typically)
Monthly difference: $35-$50 Annual difference: $420-$600
That’s a car payment every year. Or a weekend trip. Or 14 months of Netflix. Real money that compounds over time.
Green Energy: Everything vs. Nothing
There’s no nuance here.
Green Mountain:
- 100% renewable energy on every plan
- Direct contracts with Texas wind farms
- Sources from actual solar installations
- 27 years of environmental track record
- Your premium funds new renewable infrastructure
- Can document exactly where your electricity comes from
Discount Power:
- Zero green energy options
- No renewable plans available
- No carbon offsets
- No environmental positioning whatsoever
- 100% focused on lowest price
If you care about renewable energy, Discount Power literally can’t help you. If you don’t care, Green Mountain is throwing away $400+/year on something you don’t value.
Credit and Deposit Situations
Discount Power wins for credit-challenged customers.
Green Mountain: Runs credit checks. Score above 650 means no deposit. Below that? $200-$400 upfront or a letter of credit from your previous provider. No prepaid option. No workarounds. If your credit is rough, Green Mountain can’t serve you.
Discount Power: Runs credit checks for traditional plans, but offers prepaid with no credit check and no deposit. You’ll pay 10-15% more per kWh on prepaid, but it beats being turned away entirely.
If credit issues are blocking you from traditional plans, Discount Power has a path forward. Green Mountain doesn’t.
Customer Service Reality
Neither wins here.
Green Mountain:
- Phone wait times: 10-15 minutes
- Staff understand renewable energy
- Website works, nothing fancy
- No 24/7 support
Discount Power:
- Phone wait times: 30-45 minutes during peak periods
- Website looks like 2010
- Daily usage texts for prepaid customers (actually useful)
- No 24/7 support
Both companies invested in rates over service. Green Mountain is less painful to deal with, but neither will impress you.
The Environmental Math
Let’s be honest about what Green Mountain’s premium accomplishes.
Your $400-$600/year goes to:
- Actual wind farm contracts in Texas
- Solar installation partnerships
- NRG Energy corporate overhead
- Executive compensation
- Shareholder returns
Alternative: Save $500/year with Discount Power. Donate $500 to a renewable energy nonprofit. Your money probably accomplishes more without Fortune 500 overhead.
Green Mountain is legitimate—they’ve been doing this since 1997. But if maximum environmental impact is your goal, direct giving might beat electricity premiums.
The Verdict
Choose Green Mountain if:
- Genuine renewable energy is worth $400-$600/year to you
- You want 27 years of environmental receipts
- Your credit qualifies for their standard plans
- Funding renewable infrastructure through your power bill feels right
Choose Discount Power if:
- Price is your only priority
- Green energy is something you’d skip to save $400+/year
- You need prepaid due to credit challenges
- You set up autopay and forget about electricity
There is no middle option here. Green Mountain is all-green at a premium. Discount Power is all-budget with zero green. Pick based on your values and your budget. Both positions are defensible.
