Gas storage levels attract particular attention ahead of the heating season. For property owners, asset managers and property managers, however, the indicator becomes useful when linked to their own procurement: which delivery periods are covered, which prices are fixed and which consumption volumes may still change? Professional portfolio reporting should bring these questions together.
Read the date alongside the data
A storage level is always a measurement at a particular point in time. Before comparing it with a previous year or using it to inform procurement, establish the measurement date, geographic scope and calculation basis. A recent publication date does not turn an older observation into today’s storage level.
For ongoing decisions, consult the Federal Network Agency’s storage overview. It uses AGSI+ working-gas data; cushion gas that remains in storage is excluded. Late reporting may lead to revisions. A chart without a measurement date and definition is therefore an incomplete basis for decisions.
One further reporting point: a change from, for example, 50% to 55% is an increase of five percentage points. This illustrative calculation should not be confused with an increase of five percent. Consistent units prevent internal reporting from overstating or understating a market movement.
Assess supply conditions and budgets separately
The Federal Network Agency’s assessment, reviewed on 25 September 2026, describes German gas supply as stable and the risk of tight supply as low. The agency considers storage, pipeline and LNG imports, infrastructure and demand together. This assessment is a snapshot.
NeoBid’s interpretation for property portfolios is that a national supply assessment does not establish how much an individual budget may fluctuate. That requires information on price fixing, delivery periods and contractual treatment of consumption deviations. A contract may secure supply while leaving some price components variable.
Communication with owners or investment committees should therefore provide two separate answers: how are overall market conditions assessed, and which specific financial or organisational decisions are required within the portfolio? Separating these questions makes reporting actionable.
Filling targets apply to individual storage facilities
Regulatory targets also require precise allocation. Germany’s current Gas Storage Filling Level Ordinance of 5 May 2025 distinguishes the following facilities and dates:
| Date | General requirement | Facilities with different requirements |
|---|---|---|
| 1 November | 80% | 45% for Bad Lauchstädt, Frankenthal, Hähnlein, Rehden, Stockstadt and Uelsen |
| 1 February | 30% | 40% for Bierwang, Breitbrunn, Inzenham-West and Wolfersberg |
The requirements apply to each facility’s working-gas volume. The ordinance expires at the end of 31 March 2027. A national average alone therefore cannot establish whether every facility meets its applicable requirement. These figures are not procurement quotas for property businesses.
Five questions for robust portfolio reporting
In NeoBid’s view, reporting for the next procurement decision should answer five questions:
- Which period is being assessed? Clearly align market monitoring, the budget year and the supply contract. An annual average alone cannot describe winter exposure.
- Which volumes remain exposed to price changes? Show both the percentage and the corresponding volume. A percentage without a reference quantity is insufficient for assessing budget exposure.
- Which changes can already be anticipated? Include vacancy, new lettings, property disposals and planned heating-system changes in consumption forecasts. Record responsibility and the date of each assumption.
- What does the price commitment actually cover? Review contract components, volume tolerances and the treatment of excess or shortfall volumes. The label “fixed price” does not replace this review.
- Who decides, and by when? Record offer validity, contract deadlines, approval limits and cover arrangements. Market monitoring becomes effective through a defined decision process.
With tranche procurement, fixed and open volumes must also be tracked separately. Several buying dates spread timing risk but do not guarantee a lower price.
From a market indicator to a procurement decision
A practical approach is a concise decision sheet for each delivery period: data date, contract expiry, expected volume, share still exposed to price changes, available offers and the next approval deadline. Storage levels complement this sheet as market information. The decision itself follows the budget, deadlines and agreed risk limits.
NeoBid helps translate this information into an appropriate electricity and gas procurement strategy and obtain comparable supplier offers. A supply-point schedule, existing contracts and available consumption data provide a starting point. Missing information can then be added systematically.
