Non-Wires Alternatives (NWAs) Modern Energy Systems

Non-Wires Alternatives (NWAs) are becoming increasingly important in the transformation of energy systems to meet the demands of a changing power grid infrastructure. Rather than relying solely on building new power lines and substations to deliver electricity, NWAs provide localized sources of energy generation, storage, efficiency, and demand response. Implementing NWAs strategically allows utilities to defer or avoid costly investments in new transmission and distribution capacity. Additionally, NWAs enable greater integration of renewable energy and increased resilience.

Several key factors have driven the increasing adoption of NWAs in recent years. Growing electricity demand, especially peak demand, strains ageing infrastructure in many regions. Siting and building new wires solutions face lengthy planning processes as well as community opposition. Policy incentives for clean energy and decarbonization lead utilities to consider NWAs as flexible grid modernization options. New technologies, from affordable battery storage to advanced metering infrastructure and energy management systems, unlock more NWA possibilities. Greater cost competitiveness of solutions like solar photovoltaics, combined with their modularity, make them attractive alternatives.

When evaluating potential NWAs, utilities conduct detailed reliability studies and cost-benefit analyses. NWAs differ fundamentally from traditional wired infrastructure in that they are frequently distributed energy resources (DERs) with abilities to both produce and consume power. For example, targeted energy efficiency, demand response, and controllable loads can reduce stress on congested circuits. Local solar generation coupled with batteries can supply peak power without drawing from the wider grid. Some key categories of NWAs include:

• Energy efficiency – High-efficiency appliances, lighting, weatherization, etc. to permanently reduce demand
• Demand response – Incentivizing consumers to shift usage away from peak times
• Distributed generation – Solar, wind, combined heat and power systems, fuel cells
• Energy storage – Batteries, thermal storage, pumped hydro, etc.
• Voltage optimization – Smart inverters to manage voltage levels
• Microgrids – Small electric grids with DERs able to island from main grid

Proper siting of NWAs requires geospatial analysis and modelling to pinpoint optimal locations for deferring equipment upgrades. The locational value and stacked benefits of NWAs are also considered – for example, citing storage, where it can benefit both transmission and distribution needs. Ongoing metering and telemetry data enables dynamically controlling NWAs to meet the grid's changing operating conditions.

Utilities and regulators work closely to align NWA incentives and develop cost recovery mechanisms. As NWAs become a larger component of energy portfolios, new financial and business models will be needed for these distributed and potentially customer-owned resources. Already there are examples of successful NWA adoption, such as in California, where they are projected to meet over 20% of projected infrastructure needs from 2021-2026. Integrating NWAs and wired solutions will be key for utilities to transition toward the grid of the future. With thoughtful implementation, NWAs can enhance system reliability and capabilities while also increasing sustainability.

Takeaway

Non-Wires Alternatives (NWAs) offer a practical solution for modern energy systems by integrating distributed energy resources to improve efficiency and sustainability. By focusing on energy efficiency, demand response, and energy storage, utilities can alleviate the pressure on traditional infrastructure while meeting increasing electricity demands. Implementing NWAs not only promotes renewable energy integration but also enhances overall grid performance.
