DSO - Bulgaria
Publication info
| Publication status |
Published |
| Access link to GHC publication of the SO |
|
| Access type |
Open |
| Geographical Coverage |
DSO licensed territory |
| Spatial granularity |
On a DSO level, the granularity is regionally based. For example, the selection guides the user to select a city or a village. |
| Voltage Level Coverage |
DSOs are responsible to publish available capacity for MV grid (6, 10 and 20 kV) |
| Time Horizon (e.g. Y+1, Y+3 / 202x / snapshot) |
The information for available/not available capacity is a snapshot. After depletion of the capacity based on nodal principle for the respective area, the information is updated. |
| Data Format (Table, Map, etc.) |
DSO information leads the user to an urban area (e.g., village) and as a result of the user's “question” about free capacity, the user will get information in a “binary” format – available or not available capacity |
| Grid user types covered |
Solar |
| Displayed Capacity Type (e.g. available/requested/reserved/connected etc.) |
Availability of requested capacity |
| API Availability |
Openly available |
| Grid hosting capacity downloadable & format |
No, the available capacity information can be queried via a form by selecting the region |
| Update Frequency |
When needed |
| Available language |
National language(s) only |
Hosting capacity assessment
| Description for the criteria and methodologies used that lead to the published information |
NRA requires the grid operators, including the TSO to publish information about area based available capacity |
| Main assumptions/disclaimers behind calculations |
The TSO has an emerging scheme of connection. If a capacity in a primary substation is exhausted for the single transformer, they are requested to put in operation second transformed which increase the available capacity. They have in the Network development program projects to replace the primary transformers. |
| Additional information |
Additional information on flexible connection: Partial (not defined, but regulated as "temporary connection"). Equivalent through temporary schemes and capacity limitation. |
Additional information for connection request and hosting capacity information
| Connection request procedure |
In any case, available or not available capacity, the connection request should be sent to the grid operator. |
| Available options for the investors if the map shows“no capacity available” in their interested area |
Depending on the case, but in most cases the investor waits until the grid reinforcement. No flexible connections available. |
| Connection request rules/principles |
First come, first served. |
| Information published for volumes of connection requests/waiting lines |
Partly. Public register under Art. 28 of the Renewable energy Act. This page contains an electronic public register of submitted requests for connection of electricity generation facilities to the DSO network. To view the information under for a given procedure, the user needs to enter its 7-digit procedure number. The data is updated once a day and provides the status of the procedure. |
| Granularity of published connection requests/waiting lines (e.g., nodal, regional, per SO) |
Regional |
| Additional information |
There are additional functionalities according to the Renewable Act for each DSO to maintain a public register with the requested capacity. |
