BASICS OF COMING SOLAR PV AND STORAGE TECHNOLOGIES

By | blog | No Comments

Written by Nani Pradeepan, P.Eng.

As we know the intensity of solar radiation and wind can change randomly, means electricity generated from these resources will also change randomly without any notice.  In recent years wind and solar PV have been the major drivers of new electricity generation.  With this increased amount of intermittent power generation from solar and wind, energy storage is becoming an increasingly important for a number of reasons including grid stability as well as more attractive economics for project owners.  Pairing of PV and storage also increase grid security/ availability, for example against natural disasters.

Storage technologies come in a variety of forms including mechanical, thermal, and chemical. Each type of storage has a variety of specific technologies that can be used, and each has unique characteristics that differentiate them for the type of energy they generate, as well as the types of power sources with which they can be integrated or connected.

Chemical storage systems are generally battery-based systems that use chemical reactions to store/convert energy. Battery based storage systems have been widely used in many small to medium size applications and has received a lot of attention recently and considered one of the best potential mechanisms for large scale centralized and distributed PV installations.

There are many different types of battery chemistries and even more under development with new progress announced frequently. Given the varying nature of this storage type, the exact makeup of the battery systems can differ widely with each technology offering its own unique benefits and usages (e.g. long-term storage versus short-term regulation).

Today distributed energy generation has emerged as a more local energy source. Instead of offering energy that locals readily can purchase, distributed energy generation creates an opportunity for local homeowners and businesses to generate their own energy directly with local resources. Doing so will put more disposable income in their hands that in turn can be spent locally to boost the local economy. Distributed energy generation systems using solar, wind, natural gas and other local energy sources are also readily available for homeowners and business to deploy.

Distributed energy generation systems also can provide an attractive investment opportunity for investors looking to generate moderate returns at relatively low risk. Local economies can benefit by providing a way for locals to generate an attractive return on their money especially given the low yields of alternative fixed income investments today by accelerating the deployment of Distributed energy generation within their communities.

Energy efficiency is the cheapest, cleanest, and most readily available energy resource to help reduce carbon pollution. Knowledgeable and licensed professionals at New Dawn Energy Solutions perform cost effective energy audits and guarantee you get fifty percent of the audit cost from government incentives and another fifty percent in energy savings.

Our energy audit starts with analyzing your utility bills and benchmarking your building performance. Then we study your building systems holistically and identify opportunities which will bring in energy savings. Analyzing the findings and the available incentives for them we will provide you an energy plan with defined priorities to take actions appropriately.

Benchmarking your building’s energy performance is the key first step, which is part of our Audit Methodology to help you understand the energy performance of your building, compares your building’s energy performance to a similar building. Benchmarking also will help you monitor your building energy performance before and after an energy saving modification.

Benchmarking is an invaluable tool for continuously evaluating energy performance of your building and will help you in many ways.

  • objective, reliable information on energy use and the benefits of improvements
  • increases general awareness of energy efficiency among building occupants
  • prioritizes poorly performing systems for immediate improvement
  • identifies best practices that can be replicated
  • identifies what opportunities are there to improve your building’s energy performance
  • helps to develop a comprehensive energy management action plan and build the business case for capital investments

Your Energy Management team has the routine function of operation and maintenance of all the energy consuming equipment of the building and monitoring energy usage.  They may not have the time, though have the expertise, to analyze and localize energy wastage.

At New Dawn Energy Solutions, we have the expertise and time to conduct a targeted study to evaluate where energy is wasted and what cost effective improvements are possible to save energy and money.
