Probe data is analyzed to derive Longitudinal Speed Profiles (LSPs) and an Optimal Longitudinal Speed Profile (18) for each road segment or link in a digital map network. The Longitudinal Speed Profiles (LSPs) profiles are calculated during defined time spans whereas the Optimal Longitudinal Speed Profile (18) is based on the LSP for the time span corresponding only to free flow traffic conditions. All of the LSPs can used to create a respective energy cost for each time span, or only the OLSP (18) can be used (or alternatively the RRDSL 16 or LRRDSL 17) to calculate an energy cost for the free flow conditions only. The energy cost can be used to predict the energy required by a vehicle to traverse the link Navigation software can use the energy cost to plan the most energy efficient route between two locations in the digital map. Sensory signals can be activated if a driver strays from the Optimal Longitudinal Speed Profile (18) to achieve extremely high levels of energy efficiency.

Energy arbitrage by load shifting
Methods and systems are provided for realizing energy cost savings through load shifting utilizing a battery bank that may serve as a battery back-up on a premises for providing power in the event of a grid power outage or curtailment. A budget of unreserved cycles of battery charging and discharging is determined, taking into account the rated battery life in terms of both time (e.g., years) and number of cycles. That cycle budget is allocated to days of the year identified as days on which the greatest savings can be realized through load shifting. These days are identified by taking into account the peak and off-peak usage rates applicable on those days, any rate tiers that may be entered as a result of the additional energy expended to load shift, and the round trip efficiency of the charge / discharge cycles. Load shifting is executed in accordance with an established schedule of the identified days, by discharging the batteries during peak usage hours and charging the batteries during off-peak periods. In the event the budget of unreserved cycles exceeds the number of profitable days for load shifting, the depth of discharge on each cycle may be increased to realize greater savings on the scheduled days, at the tolerable cost of losing cycles not expected to be used in any event.

Framework for distribution of computer workloads based on real-time energy costs
Energy costs for conducting compute tasks at diverse data center sites are determined and are then used to route such tasks in a most efficient manner. A given compute task is first evaluated to predict potential energy consumption. The most favorable real-time energy costs for the task are determined at the various data center sites. The likely time period of the more favorable cost as well as the stability at the data center are additional factors. A workload dispatcher then forwards the selected compute task to the data center having the most favorable real-time energy costs. Among the criteria used to select the most favorable data center is a determination that the proposed center presently has the resources for the task. A stabilizer is utilized to balance the workload among the data centers. A computer implementation for performing the various steps of the cost determination and allocation is also described.
