If anything, using more energy-efficient heat pumps might even decrease the load on the network.

For solar, starting next year, you'll get less and less money for the energy you give back to the net, so you might as well us it and store it for yourself instead of letting the energy shareholders get rich with your production.
If your unit is also to be used as heat pump, well.. ..things look bleaker globaly in the Netherlands.. Especially if more and more people step over from gas to electric. No sun + cold wave (and therefore an inefficient heat pump) is going to put some people in the cold..
A smarter network could help, if the investments were sufficient. But the problem has been known since the early 2000s, and nothing has been done about it until recently.
It roughly matches the shape of the American datacenter issue where an uptick in demand that is small compared with the level of extra demand required for EVs and heat pumps and industrial electrification to decarbonise the economy has apparently caused massive problems.
And also the Australian experience where the grid companies would rather curtail solar than sell it cheaply (often because the same companies profit from evening gas prices).
You are then forced to conclude that there was simply no coherent plan for electrification. Decades of planning time utterly squandered.
Probably spent arguing about whether climate change was real.
He told me that the problem had been forecast and known since the early 2000s, and that basically nothing was done about it until very recently (think less than 5 years).
The problem was made worse with the privatization of the electricity network, as the incentive to invest in primary net infrastructure was very low.
So it's the classical case of a known problem with no will to invest, combined with successive governments that wash their hands saying "it's privatized, we cannot interfere". (so also with no will to invest)
The problem was foreseen, the plans were made and proposed with actionable steps and real deadlines, and nothing was done because the costs were too high.
And now the short-to-medium term prognosis is bleak, with blackouts a real possibility.
