Sunverge Energy (Sunverge), a California-based company, has introduced a new Solar Integration System (SIS) allowing solar energy to be stored at home, and released by the utility company during times of peak demand. The Peak solar generation typically occurs in the afternoon, several hours before peak energy demand. This new Solar Integration System (SIS) captures solar energy when it is most abundant and stores it for use when the cost of grid-tied power spikes, and so it effectively shift a household’s load from higher- to lower-priced power.
Sunverge’s SIS offers a number of distinct storage–related advantages. Customer–owned storage can be used to manage increasing costs by time–shifting low–priced energy. During peak loads, the cost to produce and deliver electricity is at its highest. Reliability is at its lowest. This SIS is designed considering the need to address the problems of peak and super–peak loads. The trouble with traditional solar systems is that peak generation typically occurs several hours before peak demand, and therefore does little to mitigate the highest costs of producing and delivering energy. In a Sunverge model, generation is distributed across multiple locations on the demand side of the meter, thereby eliminating delivery bottlenecks and ensuring reliable supply. This increases power quality, increases transmission and distribution asset efficiencies, and reduces line loss and congestion charges. The distributed storage also enables utilities to provide differentiated electric service with higher quality and/or reliability at a premium price. The integration of solar + storage in Sunverge’s system enables utilities to use distributed stores of solar energy in demand response programs. As Sunverge’s SIS is networked with the utility, demand response becomes automatic, requires no third party to initiate and no behavior change on the part of the consumer. The advantages of a properly located Sunverge Solar Integration Systems (SIS) are:
Ø reduce congestion of existing electricity transmission and distribution
Ø extend the life of aging grid infrastructure underground cables
Ø reduce the need for additional transmission capacity
Ø defer the need for expensive sub–transmission and distribution upgrades.
Ø provide utility planners and engineers with flexible, reliable and arguably less–risky alternatives to investments in conventional, inflexible T&D capacity.
The inclusion of battery storage means that demand response is guaranteed, even when it isn’t convenient for consumers to reduce power use. Through the Sunverge Data Processing Gateway (SDPG), utilities can aggregate system–wide information in real time and control localized loads and storage deployment based on sophisticated, aggregated, control algorithms. This helps utilities to better predict needed investment in generation and delivery infrastructure and more accurately forecast day– and hour–ahead demand.
