PPA Savings 2026: How Much Can a Business Really Save?

Definition. A PPA (Power Purchase Agreement) is a long-term contract under which a company buys electricity directly from a solar, wind, hydro or nuclear plant at a price fixed for 5 to 15 years. It reduces a business's electricity bill when that fixed price is below wholesale market prices.

The short answer

• A PPA costs €46/MWh on average in Europe (Pexapark index, August 2026); a solar PPA signed in Q2 2026 cost €56.59/MWh on average (LevelTen).
• Power delivered in 2027 costs about €128/MWh in Germany and €87/MWh in France on the futures market (baseload calendar contracts, 25 September 2026).
• Realistic savings: 5-20% on covered energy in a conservative scenario, over 30% if prices stay at current levels, a possible loss if the market falls below the PPA price.
• In euros: about €0.5-1.9M a year for a 10 MW data center in Germany, €20-75k for a 2 MW plant in France, a few thousand euros for a 200 kW SME.
• The main benefit is visibility: a known price for 10-15 years, while the German annual contract rose more than 50% between late 2025 and September 2026.

Why PPAs are back as a way to cut electricity costs in 2026

PPAs are attractive again because the gap between PPA prices and market prices widened in 2026. At the end of 2025, the 2026 annual contract traded around €51/MWh in France and €83/MWh in Germany, barely above PPA prices. Summer 2026 geopolitical tensions and rising gas — up roughly 30% since January according to French regulator CRE — sent 2027 contracts soaring, while renewable PPA prices stayed flat at €45-57/MWh.

That gap, and only that gap, creates savings. A PPA isn't cheaper by nature: it's cheaper when the market is expensive.

How to calculate PPA savings: the formula

Annual savings = covered volume (MWh) × [market price − (PPA price + shaping and balancing costs)]

• A PPA only touches the energy component. Network charges, taxes and levies stay. For a business site, energy is roughly 40-60% of the bill excluding VAT.
• Solar and wind follow the weather, not your consumption. Suppliers charge to reshape the profile: budget €5-15/MWh.
• The right benchmark is the average market price over the contract term, not today's price. Hence three scenarios: high, central, low.

3 worked examples: data center, industry, SME

Case 1 — 10 MW AI data center in Germany: €0.5-1.9M a year

• Consumption: 10 MW continuous → 87,600 MWh/year
• Wind + solar hybrid PPA covering 50% → 43,800 MWh/year
• PPA price €72/MWh + shaping €12/MWh → effective price €84/MWh

For data centers, a PPA also helps meet the hour-by-hour renewable targets hyperscalers demand — see our hourly matching guide.

Case 2 — 2 MW industrial site in France: €20-75k a year

• Consumption: 2 MW average over 6,000 h → 12,000 MWh/year
• Solar PPA covering 35% → 4,200 MWh/year
• PPA price €62/MWh + shaping €8/MWh → effective price €70/MWh

France is a special case: its nuclear fleet keeps wholesale prices below its neighbours', and the end of ARENH on 1 January 2026 reshaped supplier offers. More on our France market page.

Case 3 — 200 kW SME in Spain: about €7k a year

• Consumption: 200 kW over 4,000 h → 800 MWh/year
• Supplier offer backed by a solar PPA (sleeved), 50% coverage → 400 MWh/year
• PPA price €40/MWh + shaping and sleeving €12/MWh → effective price €52/MWh

Below 5-10 GWh/year, a direct PPA is rarely an option: SMEs go through a supplier, an aggregated PPA or a buying group. Gains are in the thousands of euros; the main value is a known price.

PPA, fixed-price or indexed contract: which cuts your bill most?

Electricity procurement options for businesses compared

In September 2026, a 1-3-year fixed-price contract bakes in today's high futures; a PPA locks a price tied to production cost, over a much longer term. That's why a PPA is currently the most effective way for a large consumer to cut its electricity bill durably.

What erodes savings (and how to avoid it)

• Solar cannibalisation: the more solar on the grid, the lower prices fall at production hours. In Spain, solar captured only 61% of the market price on average in 2025. A hybrid or storage-backed PPA limits this risk.
• Over-coverage: above ~70%, you resell surplus at low prices. Stay below your minimum load during production hours.
• Wrong tenor: a 15-year contract signed at a price spike can turn loss-making. Indexed prices, floors/caps, or 5-7-year deals on post-subsidy assets add flexibility.
• Extra fees: sleeving, bank guarantees, guarantees of origin (€0.2-1/MWh in France, so marginal).

For contract structures (physical, virtual, pay-as-produced, baseload), read our corporate PPA guide and our case studies by industry.

Estimate your savings in 5 steps

• Measure your consumption — annual MWh and, ideally, your hourly load curve.
• Pick a coverage ratio: 30-50% for solar, 50-70% for a wind-solar hybrid.
• Compute the effective price: PPA price + shaping/balancing + sleeving fees.
• Build three market scenarios over the contract term: high (current futures), central, low.
• Calculate savings for each and check the low scenario remains acceptable.
