I am an expert in the systems that balance electricity demand and supply.
Many systems have been created that maintain this balance over time and mitigate the cost to energy users. There are economic systems, for example, energy markets, which generate prices that indicate the value of changing the electricity flow at a particular place and time. There are regulatory systems that enforce standards on owners and operators of energy infrastructure. There are mechanical systems at power plants that keep coal flowing into the furnaces at the precise amount needed. There are forecasting systems that allow industry stakeholders to plan for the future. There are business processes that allow every kind of enterprise to interface with the grid. All these systems work in concert to keep the electrical grid energized and the electricity flowing.
Contact me if your issue intersects with any of these energy systems.
My expertise comes from over 10 years of work experience in the energy indu...
