- At 6 AM today, you purchased 1 MW of electricity contract for 12 PM at a price of 100 pounds/MWh. Two hours later, the forecast for solar generation for 12 PM has changed from 4 GW to 4.5 GW. The market is currently bid at 95 pounds/MWh and offered at 105 pounds/MWh. What would you do, and why? Please answer logically, stating all assumptions.Estimate the total land requirements for wind farms generating an amount of electric energy equal to 2008 US annual consumption (4.4 × 1012 kWeh) if individual units are rated at 2 MWe, have a rotor with a 100 m diameter, and are spaced 3 diameters side to side, 10 diameters front to rear in giant contiguous wind farms having an annual average capacity factor of 25%. Compare the required area to that of North and South Dakota (combined land area of 145,000 square miles), which have some of the best US wind resources. Discuss the factors that would favor or impede the practical implementation of a Grand Midwestern Wind Farm plan to provide the bulk of US electric energy by the year 2050.A building in a location is equipped with a heat pump system that is used for space heating in winter and cooling in summer. The seasonal COPs of the heat pump in winter and summer are estimated to be 2.2 and 2.8, respectively. The design heating load of the house is calculated to be 750,000 kJ/h for an indoor temperature of 25°C. The unit cost of electricity is $0.09/kWh. The annual heating degree-days in this location is 2400°C-days and the 97.5% winter design temperature is −9°C. The cooling degree-days are 1100°C-days. Determine the annual electricity consumption and its cost for heating and cooling of this house. Assume the same overall heat loss coefficient for winter and summer.
- A Barangay power station supplies 60KW to a load over 2500 ft, 100mm squared, two conductor copper feeders, the resistance of which is 0.078 ohm per 1000ft. The bus bar voltage is maintained constant at 600V. Determine the maximum power which can be transmitted.You want to buy electric energy. You can buy from company A, B, C, or D,but you must choose only one. You obtain past data on these four suppliers, and you then determinethat the prices for some of them have been quite volatile, influenced by the state of the economy(recession, stagnation, and inflation). You assess this data given in the table below. Assuming that you simply want to minimize your average costs over the long run, determine theexpected costs for all energy suppliers. Select the supplier based on minimum expected cost.A plant erected to manufactured socks has a first cost of P10, 000,000 with an estimated Salvage value of P100, 000 at the end of 25 years. Find its appraised value to the nearest P100 by the sinking fund Method, assuming an interest rate of 6% at the end of 10yrs?
