(2011). Uncertainties in smart grids behavior an modeling: What are the risks and vulnerabilities? How to analyze them?. //Energy Policy//, 39, 6308-6320.))((Charpentier, A. (2008). Insurability of Climate Risks. //The Geneva Papers//, 33, 91-109.))These changing circumstances have significant consequences. On the one hand, the risk of a grid failure is rising; on the other hand, risks are becoming increasingly difficult to calculate. In addition to that it raises questions about insurability and the possible rise of costs for maintaining, financing, expanding power grids. The evolving risks facing energy grids raise new questions regarding the maintenance, modernization, insurability, financeability of grids and calls for innovative efforts like smart grids ===== Shared definitions ===== Risk describes the probability of negative consequences affecting things that people value. A distinction must be made between risk assessment and risk management. Risk assessment refers to the, usually quantitative, calculation of the probability that a specific event will occur and its potential magnitude. Risk management refers to the process of dealing with risk, that is, reducing it to an acceptable level. ((Renn, O. (1998). Three decades of risk research: Accomplishments and new challenges. //Jounal of Risk Research//, 1(1), 49-71.)) Distinctions can be made between different forms of risk concepts. For instance, the classical form is technical risk, which is predominantly used by insurance companies and involves calculating the average probability of an event based on historical data. This means that the frequency with which a specific event occurred over a given period in the past is used to project the likelihood of its future occurrence. However, this approach to risk calculation reaches its limits when historical data is lacking or unavailable, as is often the case with unprecedented environmental disasters. Furthermore, technical risk analysis fails to take into account that individuals perceive risks differently and, depending on their values, may be more willing to accept certain risks than others. Technical risk therefore represents only a fraction of comprehensive risk identification, assessment, and management. For example, psychological phenomena such as cognitive biases directly influence how people perceive risk. Consequently, individual actions are driven by perceived risk rather than by scientific, rational calculations. Therefore, these individual and personal factors must be taken into account when evaluating risk. ((Renn, O. (1998). Three decades of risk research: Accomplishments and new challenges. //Jounal of Risk Research//, 1(1), 49-71.)) By distributing control capabilities to each component in the electrical grid and enabling the exchange of information between components, the grid gains a higher degree of control and flexibility This allows for better risk management and higher resilience in the event of sudden peak loads or other stressors. However, even though Smart Grids are intended to reduce risks to power grids, their own future is exposed to significant uncertainties. Thus, the development and expansion of these systems depend on a number of factors that make quantitative risk calculations difficult: the magnitude of the required investment, uncertainty regarding technological developments, unpredictable global energy demand trends, and shifting energy and environmental policies.((Zio, E., Aven, T.

Furthermore the rising need to ensure and the rise in costs of insurence, will have consequences for future investments for the expansion and modernisation of critical infrastructure as well as consequences on the cost for the end user ==== Technologies and infrastructure ==== - The growing implimentation of renuable Energy sources like solar and wind poses new challenges for power grids. - Smart meter, Flexibility of energy use. - rising Complexity - Interconnection of different parts of critical infrastructure (See Zio & Aven, 2011) ==== Institutional structures ==== - how can the state help with financing policy, lowering the Risk and therefore rise financibility of critical infrastructure ===== Distinctions and overlaps ===== ===== Related topics ===== [[topics:uncertainty|Uncertainty]] · [[topics:resilience|Resilience]] · [[topics:scenarios|Scenarios]] · [[topics:governance|Governance]] ===== Topic notes ===== **Editorial notes** — when drafting, consider: * The companion topic [[topics:uncertainty|Uncertainty]] covers the Knight distinction between risk and uncertainty in depth — Risk should focus on calculable probability, insurance, hedging, and risk distribution across actors * Risk as systemic property vs. risk as perceived by individual actors * Cross-reference with [[topics:resilience|Resilience]] (risk management vs. resilience building) and [[topics:scenarios|Scenarios]] (risk quantification in planning) ~~DISCUSSION~~
