• Energy cost reduction: off peak energy utilization

    Main Components of Energy Cost:

    #. Consumption: A charge based on a price per kWh

    #. Demand: A charge based on a price per kW, typically the peak kW of the billing period

    and ...        Customer charge

              Power factor charge

              Loss factor adjustment

              Fuel adjustment costs

              Demand response credits/penalties, Many more...


    Demand is calculated using demand intervals, a short timeframe (often 15 minutes) during which overall usage is aggregated and tracked as a total. The average calculated is the kW demand for this period. Peak shaving is the ability to control energy usage from a supplier during peak intervals, in order to limit or reduce demand penalties for the billing period.


    Electric utilities are introducing programs that encourage their customers to use electricity during off-peak hours and therefore, help to reduce their peak power demands and save money. Smart meters and home energy management systems allow customers to program how and when their home uses energy. Such programs might charge customers the actual cost of power at any one time, ranging from high prices during times of peak demand to low prices during off-peak hours. If you are able to shift your power use to off-peak times -- such as running your dishwasher late in the evening -- these programs can save you money while helping your utility. Time-based rates are very attractive to owners of plug-in hybrids and electric vehicles since typically these vehicles are recharged at night.


    Energy cost reduction: Energy Conservation

    Here is a list of things we can do to promote energy conservation:


    1. Establish energy efficient practices: We can try our best to use excess energy during the low or off peak times and encourage everyone to follow this same model and see how the energy usage decreases with more initiative.


    2. Get energy audit done: Hire an energy audit company let it do energy audit of your office/company. Many utility companies offer a free energy audit program to ensure that you are using energy efficiently. Give them a call and see if they can help you identify areas to trim down your energy needs.


    3. Replace existing bulbs with CFL’s: CFL and LED lights consume less power and offer much longer lifespan.


    4. Use hibernation feature of computers and laptops: Hibernate feature in laptops and desktops allow us to save our existing work as it is and we can continue from the same point next day. Schedule your workstation to switch to hibernate mode after working hours and during weekends.


    5. Reduce Paper Wastage: Print only when necessary. This will not only reduce paper wastage but also helps to cut energy required to run printer which in turn reduces your energy cost and makes life of your printer longer.


    6. Switch off equipment when not in use: Make sure that all printers, scanners, microwave, lights, air conditioners, coffee vending machines are switched off during weekends or holidays. They continue to draw power even if they are plugged in. Switching them off after working hours will conserve energy and reduce our energy bill.


    7. Buy energy efficient devices: Energy efficient devices cost more up front but over years of use, they’re going to save you money. This hold true for any equipment that run on electricity – spending a little more can result in significant savings over years.


    8. Invest in programmable thermostat: A programmable thermostat has the capability to automatically adjust the temperature of your workplace when no one is working. Less air conditioning can result in significant savings in billing.


    8. Keep control of your heating and cooling: Keeping home/office temperature one degree down during winters and one degree up during summers can reduce the power it uses by up to 10%.


    9. Minimize artificial lighting and make use of skylights: Artificial lights consume power, while skylights are free. Try to use maximum day light and use artificial lights in areas which are dark. Less energy means less money spent on electricity bills.


    10. Use energy saving features: Educate public regarding energy saving features of air conditioners, printers, & microwaves and let them use those features to cut energy costs. Discard old gadgets if they don’t have it and buy energy efficient peripherals.


    11. Upgrade all out-dated equipment with energy star appliances: If old heater or air conditioner is not working at its maximum efficiency, it could draw unnecessary power which may cost more money. Replace decade old heaters and air conditioners with energy star ones.


    12. Consider installing solar panels: Solar energy is free, clean and renewable source of energy. Solar panels might cost expensive initially but that cost can be recovered within few years if solar energy is used up to full strength. Solar panels last longer and have few maintenance problems. This will help to bring down monthly electricity bill.


    13. Plant shady trees outside your office: Shady landscaping outside house/office can protect it from intense sun during summers and chilly winds during winters. The tree and it’s leaves will protect from sun’s rays and less cooling would be required. If house/office already has proper insulation and energy efficient appliances, the effect will be much smaller.


    14. Discourage the excessive use of lighting or electricity: Switch off extra lights at corridors, stairs, cafeteria, reception, meeting rooms and near workstation. Try to make use of daylight as much as possible.
