Any owners out there in the PEPCO service area of MD with advice on getting the cheapest power for charging? Since we got scheduled charging on our S, we've been charging after midnight, thinking we were getting better rates. Turns out, we don't have time-of-use rates (I was originally told we did), and PEPCO is telling me that they no longer offer that plan. The only way to get tou rates is to join their pilot program for plug-in vehicles, which also REQUIRES that you buy and install a specific L2 charger that talks to their meter and only puts out 30 amps. After you spend several thousand dollars getting that done, you get marginally better rates, effectively putting your break-even point a few decades down the road. Talking to PEPCO is, of course, incredibly frustrating. I keep getting bounced around to different people and hearing very different things about the available rate plans and eligibility. Is there anything to be done?
