Installation of battery storage and connection to the Virtual Power Plant

Munich Electric-Renewable Energy Sources

General facts

Description & main goal

Installation of battery storage and connection to the Virtual Power Plant. 

The battery storage unit in Freiham, which has a capacity of 1MW, creates a central feed-in point for surplus renewable energy from decentralized and private supply units (such as PV installations). The battery storage unit is a physical element of the virtual power plant provided by SWM, enabling participation in the supra-regional power network and contributing to the stability of the energy system.

The battery storage unit was installed in November 2017 and is in operation since April 2018. 

The project is first of its kind in Munich. There is a strong in-house expertise about Virtual Power Plant in SWM. Expected efficiency gains through double functionality: storage of excess-power from PV in the district and participation in the German Market for market on balanced energy (“Regelenergiemarkt”)

Coming back to the rules: The winner in bingo is the one who gets a certain pattern on his card in the first position. Playing bingo is very simple. From the start of the game, each player is given everything they need. The shouter is then responsible for drawing the balls at random and announcing the combinations they contain at casinonic site. If they match the numbers on the card, the participant must mark the box or cover it with a token. It should also be noted that the game and its rules vary from country to country. This is the case, for example, with British or Australian bingo, where you have to fill in a whole row to win. In Belgium, bingo is a very popular slot machine that consists of a 26-hole board with 2 or 6 cards. You have to make a series of numbers that follow each other thanks to 5 balls. Once the required scheme is completed, the player must call " BINGO " to have it validated. To do this, he will be asked to confirm the numbers marked on his card. If they are identical to those of the shouting player, he will receive the winnings intended for him. Otherwise, online casinos with best games continues.
