PSEG’s own employees have shown benefits of EV ownership
The above infographic hits the high points of why they are making this offer:
- 13 employees saved $19,000 on gas in one year – that’s an average of $1,461 per employee
- 5,300 gallons of gasoline went unburned
- 50 to 60 tons of CO2 avoided
- 120,000 commuting miles driven on electricity
To encourage greater adoption of electric cars Public Service Enterprise Group (PSEG) will provide free smart charging equipment to businesses in their service area. The equipment will be offered on a first-come, first-served basis with the companies paying for installation of the equipment and electricity costs once installed. Businesses must have a minimum commitment of five employees that will use an electric vehicle (EV) for their commute. PSEG will collect usage data to gain understanding on electricity demand and impact on delivery. The program will provide equipment for about 150 cars.
“Our company believes there is a strong future in electric cars here in New Jersey, and workplace charging is a critical part of that future,” said Ralph LaRossa, president and COO of PSE&G. “We want to be a partner with New Jersey businesses and New Jersey electric car drivers. Electric cars not only benefit the environment, but are cheaper to own and operate than conventional cars.”
Employee benefits are highlighted above. Businesses achieve sustainability targets, reduce costs to employees, and improve air quality. The success of this program could see the implementation of similar programs by other power generators across the United States.
PSEG operates Public Service Electric and Gas Company (PSE&G) in New Jersey.
Why should I set an end timer?
All electric cars and many EVSEs (electric vehicle supply equipment) come with a timer that offers the ability to set a start time, end time, or both to enable you to charge your electric car within a specific time window. This article offers a sound reason to use the end timer function provided for your use.
A recent study by a company called Opower has highlighted the fact that a western US region showed higher electrical power usage by electric vehicle (EV) owners than non-EV owners, and specifically a sharp spike in power usage at midnight with usage dropping dramatically after 1:00 AM (found here). While Opower is picking on Tesla owners in the title of this blog post, they are actually targeting all EV owners. Based on their findings, there is some reason to.
Many energy companies offer time-of-use (TOU) rates for EV owners. These TOU rates may run from midnight to 5:00 AM or they may be as broad as 11:00 PM to 7:00 AM, depending upon the market and the utility company. Energy costs are significantly less during these non-peak hours as the utility companies generally have much lower demand for electricity during these times. By encouraging EV owners to charge their EVs in the middle of the night rather than in the evening when they come home, the utility ends up selling just as much power, but managing their power generation more evenly.
The challenge for the grid is that as EVs gain popularity, if everyone sets their charge timer to kick on at midnight, it can cause a huge surge in demand all at once. The way to alleviate this is to set the end time rather than the start time. Depending on the vehicle or equipment the timer may read as “Start” and “End”. Or it may read as “From” and “To”. It doesn’t really matter what the words are, but it does matter that you understand your vehicle or your equipment.
As we have learned with our range remaining indicators, there is much wiggle room in the proclamation of these numbers. The same can be said for the end time settings – these are rough estimates rather than precise determinations. Most electric cars will stop charging well before the end charge time is reached. For our purposes as EV drivers, this is fine. We still have a fully charged car so we can go where we need to go. As importantly, for the utility company, there is no large spike in demand at midnight. Rather there is a more even demand spread out throughout the the night as EV driver’s vehicles recharge with varying start and end times. The end result is that this works well for everyone involved. Do not set a start or from timer at all. The use of an end timer will provide you with the same result as using the start timer, but it works out better for the utility. Which means it will probably work out better for you when it comes time for your state’s public utilities commission to review utility rates.
