The vehicle-to-grid concept is pretty familiar by now, but visitors to a Canadian auto show are getting a sneak peek at vehicle-to-home technology developed by Nissan. That's just one of the gee-whiz technologies we're highlighting in today's Discovery Showcase installment. Scroll down and click to page 2 for a look at OG&E's data fusion project, S&C Electric's wind farm challenge in the desert, a novel power-to-gas initiative in Germany and an intriguing solar solution for the agricultural industry

 

PowerStream and Nissan demonstrate V2H technology

Calling it the latest innovation in electric vehicle technology, Nissan Canada and Ontario-based electric distribution company PowerStream are showing how a fully or

partially charged battery in an EV can provide power to a home. The companies say the vehicle-to-home (V2H) technology developed by Nissan can help homeowners on time-of-use rates (who also own a Nissan Leaf) better manage their electricity costs through load shifting. It also provides a backup power source for their homes for up to four hours during an outage. The demonstration, which is taking place during an auto show, involves the use of a Nissan Leaf plugged into a power control system (PCS) that enables the car's battery to power lights, appliances and other devices in the home. An automatic transfer switch (ATS) allows for the home's electricity supply source to be switched from the power grid to the battery in the EV through the PCS. Read more about it >>

OG&E using data to reduce cost and improve efficiency of DR

Most people seem to agree that data analytics is the Next Big Thing for the smart

grid. But many are not quite sure what to analyze first. Here's an interesting answer from Oklahoma Gas & Electric: analyze your customers. Working with data fusion company GridGlo, OG&E is segmenting and analyzing its customers so it can more accurately -- and most cost efficiently -- target its demand response programs. GridGlo's analytics platform aggregates petabytes of data and quickly analyzes it by applying proprietary algorithms and advanced data fusion processes. The company says it is the first to leverage this approach to derive novel insights in the energy industry and to provide new ways for utilities to promote customer engagement.

S&C solves grid integration challenges for Mojave wind farm

Connecting renewable energy plants to the electric grid is an important key to meeting clean energy goals, especially in California which has some of the most aggressive renewable energy goals in the country.  But as S&C Electric knows from experience, there can also be challenges with renewable energy integration. Case in point is the company's recently completed procure-construct solution to expand capacity at the Coram Wind Farm in Mojave, Calif. As S&C explains it, the project posed significant technical challenges -- including integration of a 69-kV underground transmission line that required a high level of expertise and customization, building of two substations, and installation of 13 miles of 35-kV electrical cable, three miles of 69-kV underground cable and almost two miles of 69-kV overhead cable. S&C also faced a compressed installation schedule due to delays in receiving construction permits from local authorities. Despite the obstacles, S&C got the job done on time and the wind farm can now produce up to 102 MW. Read more about it >>

Well - the Nissan demo is silly

The Nissan demonstration is silly, because you have to purchase a car to go with your home battery energy load shifting system. The car is at work during the day when the A/C is needed, right? If you use it at night to run the lights, stove and dishwasher, it will be discharged in the morning so you can't get to work, right? Just market a home battery load shifting system that sits on a pad next to your A/C and be done with it.

EV power

JZ, Tesla already makes a lithium backup system for solar .

Vehicle to Home

JZ, You ought to be able to set up your Nissan LEAF to (1)not discharge below the amount you need to get to work with [Note the average commute to work is about 10 miles, and the LEAF has almost a 100 mile pack], and (2) go back into charging mode once the power supply interruption is over, so if the juice comes back on at 3 AM, then it goes back to charging. This way, your expensive battery pack is used and useful every day, including during power outages, rather than buying a supplementary battery pack that sits there in the garage unused 99.9% of the time.

Battery wear and tear

Battery life is driven by the number of charge and discharge cycles, and the battery is a $7k-$10k replacement item on the car. The car battery might be useful during a blackout, but I would not use it on a regular basis, not without some serious compensation. This demonstration seems to be a desparation move by Nissan.
