mFRR  
As studied in [47], the mFRR product can be defined as the available active power reserves for the restoration of system frequency and, for the synchronous area consisting of more than one LFC area, the restoration of the power balance to the scheduled value. The \"m\" in its name refers to the fact that the activation of this product always takes place manually (in contrast to the previous product). In Table 2, more details on the discussed mFRR product are provided. Predictive Short-Term Local Active Product  
Considering the active power nature of this product, it can be used to respond to a forecasted system need within the timeframe of the operational planning. As a result, the product's activation can be scheduled, which lessens strain on the entire activation time and boost liquidity. The product can be purchased as a capacity-only item, an energy item, or both a capacity-only item and an energy item. To boost the liquidity of the market, this product would be purchased at least once every month. Since this would enable the activation of resources that would be closer to the location in which the need for the product has been detected, the product would need to include the additional information regarding the location of the flexibility resource that would offer the service later. Additionally, this product's ability to be activated manually or automatically sets it apart from the first two goods. Table 2 provides all the rest of the information related to this product. \begin{table}

Table 2: Cont. Predictive Long-Term Local Active Product  
This product could be used to reduce and/or postpone the requirement for additional active energy grid reinforcements, thus enabling the better management of the available budget of SOs and the redirection of the resources that would otherwise be used for those reinforcements to some of the other urgent projects in the grid. The duration of the product could extend over a long period (more than a month). Activation can either be planned or performed at the request of the SO. This product would include information about the flexibility resource location that could provide the requested service. More information on it, including the mode of activation and the minimum quantity, can be found in Table 2.  
Predictive Short-Term Local Reactive Product  
This product would be used to react to a forecasted system need within the operational planning timeframe by using the reactive power, heavily intertwined with the voltage values on the nodes in the system. In line with the specified timeframe assigned to this product, activation can be planned.
