New Zealand’s Electricity

New Zealand mainly uses renewable energy, but most of the New Zealand electricity is supplied from hydroelectric power plants, the rest are supplied from geothermal, wind and heat. Since 1974, electricity demand has increased by an average of 1% per year, increasing by 0.6% from 2005 to 2011. Compared to economic production, New Zealand is known as one of the countries with the lowest energy efficiency, but the list of countries listed in terms of energy intensity has a small worldwide energy average.

For example, in New Zealand, electricity and power generation are separated from the transmission and retail activities. I chose New Zealand electricity as my role model, but the power of New Zealand is a huge industry like a public utility, so we need a big initial investment. However, it can be represented by a downward sloping average cost curve. Likewise, the best way is to generate quantities and charge prices with MR = MC (marginal revenue = marginal cost) as all companies always want to get the maximum benefit or minimize losses It is to do. As the price of electricity rises, people only have to pay for it. As a result, it may produce the same amount, but the price price, and it will charge higher price when P goes below normal level. The government applies the highest price P '', resulting in Q '. Here, P = MC. This will be a lower profit than normal

Economic and demographic variables were used to predict New Zealand's electricity consumption to investigate the impact of selected economic and demographic variables on New Zealand's annual electricity consumption. In this survey we used the New Zealand gross domestic product (GDP), average electricity price, and population from 1965 to 1999. The model was developed using multiple regression analysis. We found that power consumption is effectively correlated with all variables. Forecasts made using these models are compared with several available national forecasts. Forecasts were also compared with predictions of previously developed logistic models. We proposed a power consumption prediction model of domestic and foreign sector based on New Zealand's economic factors and total consumption using multiple linear regression.
