Prosumer in Moldova 2026 — Complete Guide: What It Is, How to Become One, Net Billing
Everything you need to know about prosumer status in Moldova: how net billing has worked since 2024, the 100 MW national cap, how to apply and how much you can save.
Since January 1, 2024, any solar panel owner in Moldova automatically becomes a prosumer. This status fundamentally changes how electricity produced at home is metered and billed. If you're installing a solar system in 2026, you'll operate under the net billing (facturare netă) mechanism — not the old net metering (contorizare netă) scheme. Here's everything you need to know before signing a contract.
What is a prosumer?
A prosumer (producer + consumer) is a customer who produces their own electricity while simultaneously consuming from the grid. In the Republic of Moldova, prosumer status is regulated by Law No. 10/2016 on the promotion of renewable energy and subsequent ANRE regulations.
In practice: solar panels on your roof produce energy during the day. What you consume directly saves money on your bill. The surplus is fed into the national grid, and your supplier credits you financially for it.
Two main types of systems for prosumers:
- **On-grid** (grid-connected, no battery) — the most widespread and affordable option. Only works when there's grid power.
- **Hybrid** (with battery storage) — stores produced energy for nighttime use or during outages. 30–40% more expensive, but grid-independent.
Net Metering vs Net Billing
Many homeowners confuse the two mechanisms. They differ fundamentally in financial logic.
| Parameter | Net Metering (until 2023) | Net Billing (from 2024) |
|---|---|---|
| Principle | kWh-for-kWh exchange | Sale at market price |
| Price of energy fed in | Equal to consumption tariff (2.88 MDL/kWh) | Monthly average purchase price (~1.2–1.8 MDL/kWh) |
| Grid costs | Borne by supplier | Borne by prosumer |
| Credit rollover | Physical kWh | MDL (financial credit) |
| Annual surplus payment | No | No — balance resets |
| Status | Closed (capacity exhausted) | Active since January 1, 2024 |
**What this means in practice:** under net billing, energy fed into the grid is compensated at roughly half the rate you pay for consumption. It is therefore always more advantageous to self-consume your own energy than to export it to the grid. Size your system to cover your own consumption — not to generate large surpluses.
Monthly bill formula: Amount due = (kWh consumed × 2.88 MDL) − (kWh exported × ANRE monthly average price). If the result is negative, the difference carries over as a credit for the next month — but is not paid out in cash.
The 100 MW Cap: How Much Is Left?
Moldova has a national cap of 100 MW of total installed prosumer capacity. This is not a per-person limit — it's the total capacity allowed on the national grid for systems without a battery.
Status as of mid-2025:
- Installed capacity: ~46 MW (46% of cap)
- Remaining capacity: ~54 MW
- Average monthly installation rate: ~2–3 MW
- Estimated cap exhaustion: 18–24 months from mid-2025
**What happens after the cap is exhausted?** New grid connections will only be possible with a battery (hybrid or off-grid system). A system with battery storage costs 30–40% more than an on-grid one. If you're planning an on-grid system, 2026 is the optimal time.
How to Become a Prosumer: Step-by-Step
The entire process is handled by your ANRE-certified installer — you don't need to visit supplier offices in person.
- **Choose your system and installer** — verify the installer is in the ANRE registry (anre.md). All SolarMD-verified installers automatically meet this requirement.
- **Sign the contract and pay the deposit** — the installer prepares the technical design and requests grid connection approval.
- **Installation** — takes 1–3 days for a private home. Panels, inverter and cabling are installed.
- **Connection dossier** — the installer submits documentation to Premier Energy (central/south zone) or RED Nord (north zone): technical design, equipment specifications, electrical diagram.
- **Bidirectional meter installation** — at the supplier's expense, within 15–30 working days.
- **Signing the prosumer contract** — with your energy supplier. From this point you are officially a prosumer.
- **Commissioning** — electrical laboratory inspection and system startup.
**Your cost:** 0 MDL for the bidirectional meter and connection — these are borne by the supplier by law.
How Much Can a Prosumer Really Save?
Concrete example for a 5 kWp system installed in Chișinău:
| Indicator | Value |
|---|---|
| Estimated annual production | ~6,500 kWh/year |
| Self-consumption (70%) | ~4,550 kWh → savings 13,100 MDL/year |
| Fed into grid (30%) | ~1,950 kWh → credit ~2,900 MDL/year |
| Total annual savings | ~16,000 MDL/year |
| System cost (5 kWp) | ~75,000–90,000 MDL |
| Payback without subsidy | 5–6 years |
| Payback with Casa Verde (50%) | 3–4 years |
With the Casa Verde 2026 subsidy (grant up to 200,000 MDL, 50% of cost), the initial investment is halved and the payback period drops significantly.
Frequently Asked Questions
**Can I become a prosumer if I live in an apartment block?** Technically yes, but it requires majority consent from the homeowners' association and approval from the supplier. The system is sized for the building's common consumption (stairwell lighting, lift, pumps). Several buildings in Chișinău have already installed pilot systems in 2023–2024.
**What happens to energy produced at night?** At night, an on-grid system produces nothing — you consume from the grid at the standard tariff. During the day, surplus energy fed into the grid generates a financial credit that reduces future bills.
**Is the 100 MW cap per person?** No. It's the total national cap for on-grid systems. Per household, the practical limit is your contracted power with the supplier (typically 3–10 kW for residential use).
**Can I install a system without a battery?** Yes. On-grid systems (without batteries) are the most popular and affordable. They remain available as long as the national 100 MW cap is not exhausted.
**What happens after the 100 MW cap is reached?** New on-grid connections will be blocked. Only hybrid systems (with battery) will remain available, at 30–40% higher cost.
**Can I withdraw accumulated credit as cash?** No. Credit only reduces future electricity bills. Any positive balance remaining at year-end is reset — it is not paid out.
**How do I find the current month's purchase price?** On the ANRE website (anre.md), in the prosumer section. The price changes monthly based on the wholesale energy market.
