GENEX 2027 Georgia: What Business Must Change Before Hourly Pricing
How the Georgian Energy Exchange is built, what already works, what is delayed to 2027 — and what that means for your CAPEX on solar and energy storage.
Liberalising Georgia’s power sector is one of the region’s biggest infrastructure projects — and one of the most delayed. Under Energy Community commitments, Georgia is moving toward the European Target Model. The centrepiece is GENEX (Georgian Energy Exchange / საქართველოს ენერგეტიკული ბირჟა). Below: how the platform works, which segments are live, and why owners of commercial solar plants cannot wait until 2027 to “think about storage”.
What GENEX is — and why it was created
GENEX was founded in December 2019 on a parity basis by two state operators: GSE (Georgian State Electrosystem — transmission) and ESCO (Electricity System Commercial Operator — wholesale commercial operator).
Before the exchange, the market ran on long-term bilateral contracts, fixed tariffs, subsidies, and centralised imbalance settlement via ESCO. GENEX’s job is to replace opaque administrative mechanisms with open exchange pricing based on real supply and demand.
GENEX market segments
The trading system follows European practice and splits the wholesale market into four segments:
| Segment | Horizon | Status |
|---|---|---|
| Day-Ahead (DAM) | Hourly contracts, day before delivery | Live (transition) |
| Intraday (IDM) | Same-day position adjustments | Live (transition) |
| OTC | Bilateral standardised deals | Live (deal registration) |
| Balancing & Ancillary | Real-time deviations and frequency support | Deferred → 1 Jul 2027 |
Transition mode: what is live today
After delays from 2021–2024, GENEX opened DAM and IDM trading on 1 July 2024. The launch is hybrid:
- Voluntary participation — not all licensees must trade yet. Large direct consumers, network operators (losses), and some free generators are on the exchange.
- ESCO in parallel — guaranteed offtake / fixed-tariff PPAs for hydropower still run, which limits free liquidity on the exchange.
- Balancing market postponed — full mandatory hourly balancing and system services are scheduled for 1 July 2027.
Why reform needs until 2027
- Hydro seasonality — over ~75% of generation is hydro. Spring/summer surplus and export; winter deficit, import and expensive thermal. Spot pricing without storage means sharp volatility.
- Smart metering — full hourly clearing needs telemetry and hourly meters across generation, distribution and large consumption. Roll-out is still underway.
- Price-shock risk — a hard cut to market quotes without buffers can spike bills for industry and commerce.
What this means for your business plant
Today many sites already feel the “scissors” of Net-Billing: export at wholesale tetri, import at full commercial tariff. GENEX adds another layer: when balancing becomes mandatory and hourly, a station that only dumps midday kilowatts and buys evenings back will be punished harder — not by opinion, but by settlement math.
Practical CAPEX rule: design hybrid + energy storage for self-consumption and peak control now. Strategies such as UPS, self-consumption and Smart Trading are not “cloud promises” — they are how a site turns hardware into an asset. That architecture is documented in the partner briefing INVERSOL FLEX · PowerWallet & GENEX.
Owner checklist before 2027
- Map critical vs non-critical loads (what survives a blackout / peak).
- Size storage for evening peaks — not only for “pretty midday charts”.
- Prefer hybrid architecture that can run strategies (not on-grid only).
- Demand accredited install — floating neutral and CT mistakes kill CAPEX faster than tariffs.
- Request a site quote from Inversol (Tbilisi warehouse; partners install).
Regional integration (context)
GENEX is also a gateway for cross-border trade (Turkey, Azerbaijan, Armenia) and, longer term, the Black Sea Energy Submarine Cable toward the EU. For a Georgian hotel, plant or warehouse the near-term lever is simpler: stop buying a “today-only” plant.

Frequently Asked Questions
Is GENEX already working?
Day-Ahead and Intraday markets have operated since 1 July 2024 in a transitional, partly voluntary regime. Full balancing and ancillary services are scheduled for 1 July 2027.
Why should a business care before 2027?
A plant designed only for today’s Net-Billing scissors can become more expensive under mandatory hourly balancing. Hybrid + energy storage and operating strategies should be in CAPEX now.
How does this relate to Net-Billing?
Net-Billing already pays export at wholesale tetri and charges import at full commercial tariff. GENEX adds wholesale hourly dynamics — storage and self-consumption become even more valuable.
Where does Inversol fit?
Inversol supplies hybrid inverters and energy storage from Tbilisi stock; accredited partners install. The INVERSOL FLEX briefing covers PowerWallet strategies for GENEX readiness.
Who should I contact for a site quote?
Use the Contact page or WhatsApp with approximate load and critical circuits. We propose a scenario and warehouse hardware.
Size the plant for 2027 — not only for today
Inversol will map loads, propose hybrid + energy storage from Tbilisi stock, and connect accredited partners for install.
