After a year playing a key role in the Regional Energy Strategy (RES) Achterhoek as project manager Electricity, Climate Mitigation and Change Management’s director has been asked to take over the programme management for the RES Achterhoek as well. Tasks include:
- Draft the progress report (due summer 2023): it will answer the key question: is the region on course for realising its target in the year 2030.
- Integral programming of the target of 1.35 TWh renewable energy, notably wind power and solar power. Basically, the programme will outline what type and size of project will be realised when and where.
- Draft the end report for the Regional Energy Strategy 2.0
Congestion of the current electrical infrastructure is predominant in large parts of the Netherlands and that is also true for the Achterhoek. At the same, time Liander and TenneT are working hard on expansion of the capacity of the power grid. The expansion in power terms is in absolute terms substantial, in light of the necessary growth of renewable energy power, it is clear grid resources are only sufficient if an efficient approach of programming power is taken.
Because of the huge difference in full load hours between wind (3500 h) and solar power (1000 h), one can win 3.5 times higher renewable energy or CO2 reduction gains with wind power as with solar power with the same investment in infrastructure. Complementary patterns of the two sources during day and over the seasons makes a ratio of 1 to 1 in power to be seen as system efficient.
In energy terms the energy mix of wind/solar should be 3.5 to 1. Nationally, the trend is that solar power grows faster than wind power. Keeping this ratio in check will be one of the challenges for the region Achterhoek.
