I have a question regarding the bounding of an activity by its capacity (EQ_CAPACT).

First, at p.160 of the part II documentation of the TIMES model, it says that within one period, the activity is assumed constant.

However, by looking at the different types of investment cases in detail, it seems, resulting from a new investment within that period, the available capacity differs for the different years within that period. 

An example for investment case 1.a at p.143 of part II of the TIMES documentation, one can see that the available capacity in the first year of the period is equal to 3 'blocks', for the second and third year of the period, it is 4 'blocks' and in the final year of the period, it is again 3 'blocks'.

Also, because investments made in a specific period can result in available capacity at (the end of) the previous period or during the beginning of one of the following period(s), it is clear that the available capacity within a given period differs for different years within 1 period.

So my question finally is: there seems to be a discrepancy between a constant activity within one period (p.160) and an activity bounded by an available capacity (which varies for different years within that period), or am I wrong?

The only explanation that I can think of is that TIMES only produces one EQ_CAPACT for each period (possibly for every TS within the representative year M(t) of that period though), but this would result in errors (as in some years of that period, the constant activity exceeds the available capacity, or on the other hand, that the activity in some years would be bounded by a too low capacity).

Thanks in advance for helping me clearing this out!
