How to Win a FER-X Bid
Complete guidance on auction rules, bond requirements, priority criteria, and pricing strategy — based on Decree 457/2024 and GSE Round 1 & 2 outcomes.
The Bid Process
Five phases from project eligibility to CfD activation. Each phase has specific deadlines and documentation requirements.
Verify Eligibility & Gather Documentation
Confirm your project qualifies: capacity >1 MW requires auction participation. Projects ≤1 MW that started construction after 28 Feb 2025 can access incentives directly. Prepare grid connection permit, building permit, and environmental clearances.
- Grid connection permit (autorizzazione allacciamento)
- Construction/operation permit
- Environmental Impact Assessment (VIA) if required
- Land ownership or lease agreements
Calculate Your Reduction Offer
Bids must specify a percentage reduction on the higher operating price. The GSE ranks bids by this reduction — higher reduction = better ranking. Analyse Round 1 & 2 data: solar bids averaged 8.8% below cap in Round 1, 27.7% in Round 2.
- Model LCOE against operating price reference
- Apply at minimum 10–15% reduction to be competitive
- For NZIA Round: price premium ~17% vs standard round
- Account for ISTAT annual indexation of award price
Submit Bid Bond
Deliver a bid bond equal to 50% of the performance bond value at the time of application. The performance bond = 10% of expected CapEx. Failure to provide the performance bond within 90 days of results results in forfeiture of the bid bond.
- Bid bond = 50% × (10% × expected CapEx)
- Bank guarantee or surety bond accepted
- Performance bond due within 90 days of results
- Bond amount updated per ISTAT consumer price index
GSE Evaluation & Ranking Publication
GSE verifies that bids below the operating price correspond to at least the target quota +5%. If not met, 5% of total submitted power is excluded from ranking. Rankings published within 90 days of auction close.
- GSE publishes ranking within 90 days
- Priority criteria applied to equal-priced bids
- Partial awards possible within capacity limits
- Results include operating price for awarded projects
Commissioning & CfD Activation
Awarded projects must start operation within 36 months from publication of rankings. CfD payments begin at commissioning. Monthly settlement: if PUN > strike price, operator pays back the difference; if PUN < strike price, operator receives compensation.
- Commission within 36 months or lose incentive
- CfD settlement based on monthly PUN vs. strike price
- Annual award price update per ISTAT CPI
- Report production data to GSE monthly

Operating Price Reference
Operating prices are the maximum bid caps set by GSE. Your bid must specify a percentage reduction below these prices. Higher reduction = better ranking.
| Technology | Operating Price Cap | Round 1 Avg | Round 2 Avg | LCOE Benchmark |
|---|---|---|---|---|
Solar PV (Ground-mounted, >1 MW) High irradiance (South Italy) LCOE ~€48/MWh; North ~€58/MWh | €73.00/MWh | €56.83/MWh | €66.37/MWh | €48–58/MWh |
Onshore Wind (>1 MW) Round 1 only 29 projects awarded; significant headroom remains in 4 GW cap | ~€85–95/MWh | €72.85/MWh | N/A | €65–75/MWh |
Solar PV Rooftop (with asbestos removal) Asbestos removal qualifies for ranking priority — can bid higher and still rank well | Premium over ground-mount | Priority ranking | Priority ranking | €55–70/MWh |
Solar PV + Storage (co-located) Co-located storage receives ranking priority; model merchant revenue from storage separately | Standard + storage premium | Priority ranking | Priority ranking | €60–80/MWh (blended) |
Small Hydro (>1 MW) 0.63 GW cap; no awards in Rounds 1 or 2 — first mover opportunity in Round 3 | Hydro-specific rate | Not yet awarded | Not yet awarded | €50–90/MWh |
- Bid 20–30% below operating cap for solar to be competitive (based on Round 2 data)
- Wind bidders can bid closer to cap (14–20% below) given lower competition
- Priority criteria can allow slightly higher bids if your project qualifies
- With 2025 PUN ~€118–131/MWh, a €57/MWh strike price creates ~€60–74/MWh payback obligation
- Model energy price scenarios — the CfD protects downside but caps upside
- Consider curtailment risk in South Italy before setting project economics

Bid Calculator
Estimate your strike price, bond obligations, and CfD payback exposure based on your project parameters.
2025 avg ~€124/MWh. Adjust to model CfD payback scenarios.
Bid bond required at submission. Performance bond due within 90 days of award. CapEx estimate is indicative — use your project-specific figures.
Under a two-way CfD, net revenue always equals your strike price × generation — regardless of PUN. When PUN > strike you pay the difference to GSE; when PUN < strike GSE tops you up. Estimates use ~1,750 full-load hours (Italian solar average).
Priority Criteria
When bids offer the same price reduction, these criteria determine ranking. Qualifying for even one criterion can be decisive in a competitive auction.
Asbestos/Eternit Roof Removal
PV plants installed on roofs that remove asbestos or eternit receive the highest ranking priority. Projects must demonstrate certified asbestos removal as part of the construction works.
Highest priority — can bid higher price and still rank competitively
Designated Suitable Areas (Aree Idonee)
Plants constructed in areas designated as "aree idonee" (suitable areas) under national and regional planning frameworks receive second-tier priority in the ranking.
Second priority — strong advantage for pre-permitted projects in designated zones
Co-located Energy Storage (BESS)
Plants co-located with battery energy storage systems (BESS) receive third-tier ranking priority. Storage capacity must be genuinely co-located and operationally integrated.
Third priority — also adds merchant revenue potential from storage services
Long-Term PPA (≥10 Years)
Projects that have signed a Power Purchase Agreement with a tenor of at least 10 years receive fourth-tier ranking priority. The PPA must be with a creditworthy offtaker.
Fourth priority — also reduces project financing cost and improves debt terms
Yes — a project can qualify for multiple criteria simultaneously (e.g., a rooftop PV project on an asbestos roof in an area idonea with a 10-year PPA would qualify for P1, P2, and P4). In practice, stacking criteria gives significant ranking advantage and may allow bidding closer to the operating cap while remaining competitive. Projects in southern Italy with co-located storage and long-term PPAs represent the most defensible bid positions.
