PowerLedger as a project is not so much about the tech anymore rather then their ability to get customers, trials and government backing on board and to expand into international markets.

It is more about accelerating their rate of growth. As a first mover in the space, others are copypasting what PowerLedger does and are racing to take their share of the market. The blockchain technology by now has most likely proven that it is able to act as a secure, fast and transparent database to settle energy transactions.

So in the end, the projects success is entirely dependent on the rate of adoption in the following years and whether or not the trials they are running will be successful. The Asset germination events will also play a huge role in whether or not people are going to trust this project and the team. When they can deliver more or less on time and the AGE's work as they are supposed to work, there is no reason to doubt the capabilities of this movement.

As for how they can improve in general? The only thing that has been lacking for a few weeks is news about progress (How are the trials going for example?). I dont know if that has to do with nothing really happening or NDA's between PowerLedger and their partners or because all their energy is being put into finishing the Asset germination Events but it has been a little quiet lately.
