How Downed Communication Systems Could Delay Power Restoration
06/12/19
“How do fallen communication systems exacerbate power outages?”
When a power outage occurs, interdependent infrastructure systems will fail. When the phones and internet that makes up the communication infrastructure also fails, then it will make it more difficult for utility workers to bring power online. This is How Downed Communication Systems Could Delay Power Restoration.
Energy Storage Tariffs
06/11/19
“How can you be paid for your energy storage?”
Energy storage is one of the most crucial technologies for the energy transition. And like solar before it, it will need some help from policy to get its feet on the ground. One of the things it can use are feed-in tariffs, so that any energy sent to the grid will be compensated financially. These Energy Storage Tariffs are being discussed by multiple energy market operators around the world.

Fire Season
06/10/19
“When do fires typically occur?”
Wildfires and resilience are hot topics right now in California. These usually occur during drier and hotter times of the year, when foliage conditions are more ripe for an outburst. That is why during Fire Season California needs to be much more prepared to take action.
Why Dry Foliage Is More Susceptible to Fires
06/09/19
“Why is dry foliage so ignitable?”
In the wake of the recent California fires, more and more focus is going into preventing more fires. One of the root causes of all of this is the fact that when foliage dries up, it loses moisture, which prevent fires. This is Why Dry Foliage Is More Susceptible to Fires.
Backfeeding
06/08/19
“How can electricity flow in the opposite of the intended direction?”
Electricity is designed to be flown in a single direction from a generator. However, if said generator experiences a fault and needs to shut down, then electricity will flow back and be used for its own local loads. This Backfeeding can be quite dangerous and organizations need to design their equipment so everything works smoothly.

Water and Electricity Interdependence
06/07/19
“How are water and electricity directly interrelated?”
Water and electricity, two of humanity’s most vital resources, are often thought as being from completely different worlds. However, the reality is that the generation of one resource uses some of the other! To illustrate, water needs to be pumped through mechanical pumps reliant on electricity while power plants use water for their operation. In this way there is Water and Electricity Interdependence. So every time you let the faucet run, you’re not only wasting water but also electricity!
Electricity Markets
06/06/19
“How can energy be bought and sold?”
Energy is one of the most vital parts of modern infrastructure. And in many countries, deregulation has led to Energy markets, or platforms where electricity can be bought, sold, and distributed. The pricing for electricity markets depend on the current supply, demand, and mix of energy resources.
Logical Interdependence
06/05/19
“How can different infrastructures be interdependent without any direct connection?”
Infrastructures can be interdependent in numerous ways. However, one of the most subtle forms is through cause and effect, in which the consequences of one infrastructure failure will carry over into another one. Take for example the 2018 Northern California Wildfires. When the fallen transmission line caused a fire, the smoke that swept into the Bay Area caused the air pollution levels to skyrocket. This made people rush to the hardware stores to purchase protective masks, emptying stocks within hours. Through Logical Interdependence, the supply of gas masks was contingent on the fire resilience in Northern California.
The Trade-Offs Between Distributed and Concentrated Energy Generation for Resilience
06/04/19
“What resilience trade-offs are there between using distributed and concentrated energy generation?”
Both distributed and concentrated energy generation supporters argue that their preferred energy generation method is superior. Distributed supporters say that their preferred method allows for generation to be much closer to consumption loads, undercutting the need for long transmission lines, while concentrated supporters say that their base load profiles allows for the necessary amount of energy to be delivered throughout the day. When selecting new energy methods, these must be taken into consideration during construction. These are The Trade-Offs Between Distributed and Concentrated Energy Generation for Resilience.
