Going “100 percent renewable” is a worthwhile and important goal, but it’s a challenging proposition technically. That’s not stopping cities, states and corporations from adding their names to a list that grows daily. We explore the different meanings of this term, and the challenges of getting there:
Growth in microgrid markets worldwide is leading energy developers to ask how they might adapt distributed renewable energy projects to the future. Now both HOMER Pro and HOMER Grid have multi-year modules, which can model the cost of utility rate escalations, load growth – and the degradation of PV and batteries over time.
We are in the midst of a critical paradigm shift as our energy system evolves from a centralized power plant model to a complex array of smaller, distributed energy networks that incorporate multiple – primarily renewable – technologies. Driven by the new cost advantages of renewable energy, as well as an urgent need to reduce our carbon emissions, these changes are upending century-old beliefs about how energy should be produced and distributed. HOMER Energy CEO and co-founder Dr. Peter Lilienthal explains the new principles that should guide our energy decisions:
In general, putting all options on the table seems like good policy advice and normally it is. With respect to energy and climate policy it is a way to avoid antagonizing proponents of conventional energy sources. In the context of phasing out fossil fuels, it really boils down to the two carbon-free sources with the greatest potential: solar and nuclear. We explore the choices:
Conventional wisdom used to be that rural communities would get energy access through connections to the central grid. Now it’s clear that in developing countries, distributed renewable energy is a faster, cheaper and cleaner route to electricity.
This year’s HOMER International Microgrid Conference featured several important presentations on the role of communities in the planning and maintenance of successful microgrid projects. For that reason we’ve […]
By Cycle Charging during periods of low net load, the Combined Dispatch algorithm helps avoid using a diesel generator at low loads. By Load Following during periods of high net load, the algorithm maximizes the use of available renewable energy. Due to this flexibility of being able to account for both high and low loads, the Combined Dispatch algorithm is a better option than choosing between Load Following or Cycle Charging (and potentially making the wrong choice). It is also a better option than running both strategies by default, which doubles the processing time. On top of that, we’ve seen that Combined Dispatch can perform as well, if not better than, either Load Following or Cycle Charging.
